Spinning is a BAD BAD thing! What you don't realize is that the spin of most smaller rocks is multi-axis, which means that there is no point over the rock which you can orbit continuously, only a carefully guided powered hover burning relatively large quantities of rocket fuel. It also means no tethers, no elevators. Also, unless you are on one of those rocks like Vesta that are spherical, the slight gravity will be different depending on where you are on the rock.

How can you spin in more than one direction at a time? If you spin any object you are going to have a single axis of spin. If you add some spin in a different direction you are going to change the axis of spin but you are still going to have only one spin axis. Have you ever heard of a planet with two Geographic North Poles? Suppose we added a second spin to the Earth so that the second North Pole was in Miami, Florida, Could the Earth retain its first North Pole and also have a second? I don't think this is possible.

Also asteroids come in a variety of sizes and are in a variety of orbits around the Sun. One can "cherry pick" the asteroids, find an Earth Orbit crosser, one that only needs a slight nudge to end up in a more convenient orbit, ideally to orbit the Earth where it can be worked on continously. You don't need bombs to mudge an asteroid, a mass driver will do. You can exert a steady and gradual push on the asteroid, cange the orbit just enough so that the asteroid intercepts the Moon. The Lunar gravity can act as a break on the asteroid causing it to drop into an orbit around the Earth. If the orbit is set right, it will be some time before the Moon intercepts the asteroid again at its furthest point and it will give plenty of time to mine the asteroid while it is in Earth Orbit. Further nudgeing will bring the asteroid out of the Moon's reach. The Moon can serve another purpose besides as a source of materials.

This also means that you aren't going to be "taking apart" a rock, because your ability to pull ore from the surface is limited by your ability to dig down and grab the ore in the first place. Since you have near-zero gravity, you have no down force to do this digging. And since you have no stable orbital axis, you will have to burn quite a bit of fuel to get the ore back to the space refinery.

This also wrecks the use of solar power on the surface, the panels just don't face the sun, and the spinning of the rock will ensure that no practical gimbals system or panel density will be practical.

Bulk radiation shielding is worthless, its too much trouble to haul it from anywhere that requires rocket fuel for transit. Boron-doped or Hydrogen-impregnated polyethylene from Earth or Mars will be the obvious choice for space ship radiation armor.

In a cycling orbit spaceship, you only have to place the shielding their once, and the cycling spaceship simply follows its orbit from Earth to Mars and Mars to Earth, it doesn't not accelerate under its own power, so the mass of the shielding once its brought there is irrelevant.

And who cares about asteroid volatiles? Those volatiles are so far away on a rock that you can't effectively dig on nor regularly receive shipments from. The Earth with a true "no kidding" RLV fleet and the Moon's unlimited supply of Oxygen will do just fine, especially since we'll already be there anyway.

Not all asteroids are far away, and not all asteroids are in the asteroid belt. Through orbital interactions with the planets, some asteroids are in more convenient orbits for us to exploit. Some asteroids coorbit the Sun in approximately the same orbit that the Earth follows, and there is always the possibility that Earth Trojans may exist.

Terrorism is a military tactic, not an opponent.

Terrorism is pure murder and nothing else, it is not justified by any military goal, it purpose is entirely to kill civilians and no one else. When you bomb a military target and kill civilians in the process, that is not terrorism, that is collateral damage, but if you target the civilians themselves with no other purpose but to murder them, that is terrorism. I keep telling you this over and over, but you insist on using your own definition of terrorism. The Holocaust was terrorism, its entire purpose was to kill civilians that were not involved in the conflict Germany was fighting, the Holocaust had no military justification, and it was an act of terrorism on a grand scale.

It has been used by every military force in history, including the American military during the War of Independence.

You are talking about individual soldiers commiting murder because they are mad at the enemy that is shooting at them, in all such cases, these murders served no military purpose other than to satisfy the individual soldiers thist for revenge. Alot of soldiers also raped, looted and plundered, these activities served no military purpose, killing individual civilians does not defeat the enemy, and is therefore not justified as a military action, it is only murder. The military authorities did not order these actions in the case of America, they were all based on individual actions of individual soldiers a case of poor disappline and insubordination in other words, not an organized activity such as was the case of the Holocaust.

It's used by a weak small force to combat a large strong one.

It is also used by a strong military force to exterminate a weak opponent, as the Germans thus exterminated the Jews.

Stopping use of a military tactic requires conventions and police action, not military combat.

You can turn an asymmetric combat situation into a symmetric one, in which case the greater force wins. The enemy can be deterred from using terrorism as a tactic if it understands that terrorism can also be used against his people, if his asymmetric combat is made symmetric then he loses, that is how the North beat the South in the Civil War. The North had the preponderance of forces, superior numbers of troops and equipment, and towards the end of the Civil War when the Confederates were getting desperate, they started using Asymmetric combat techniques. William T. Sherman simply made it clear to them through his actions, that the South's Asymmetric strategy would be made symmetric and the South would be made to suffer all the greater, and that pursuaded the South to end the War rather than face devastation by a vengeful Northern Army. Israel does not exactly symmetrise the War, but pursuing the terrorists does have consequences for the civilians living around those terrorists. If the Palestinians don't want to live in a battlefield, then they should stop harboring terrorists in their community and then the Israeli gunships will have no reason to visit them, seems logical enough to me.

The "war on terrorism" can't ever be won. The sort of thing involved with the land mine ban is the only thing that can work.

If both sides are suffering from this tactic, then both sides have reason not to use it, especially the side with the weaker forces.

As for Israel/Palestine, the point we've been trying to get through to you is Israel has used terrorism just as much as Palestine. If you want to rant on someone using terrorism, you have to include Israel. I know it isn't politically correct for someone in New York to criticize Jews, but reality is they aren't in better moral position than Palestine. I'm not justifying Palestinian use of terrorism, rather I'm criticizing Israeli use of it. Resolving that conflict can only occur when you start by treating both sides as equal; and they are equal. I saw a TV interview with Jimmy Carter and one pundit pointed out the Carter institute made a policy of starting negotiations without name calling. That means you can't call Palestinians terrorists, and you can't call Israel a terrorist state. Hard to do when reality is they are both guilty. Well, at least I treat them as equal; one prerequisite to starting peace negotiations.

So you think Timothy McVeigh should have been treated as the equal of the United States Government because he used terrorism and as you say the United States used terrorism against say the Indians for example? So instead of arresting Timothy McVeigh the US Government should have sent a representative to negotiate with him and to sign a peace treaty?

I say Timothy McVeigh was wrong and the US government was right to arrest and execute him, just because there are two sides does in no way mean that both sides are morally equal. Just as I use my independent judgement to decide that Timothy McVeigh was wrong to blow up that building with children in it, I also use my independent judgement to determine that the Palestinians are also more wrong for murdering innocent civilians without justification than the Israelis.

I can think of one good reason. Vladimir Putin!.....I don't like the fact that he goes around ordering the assassinations of Russian citizens in foreign countries using Polonium 210.

It is the most likely explainaition: Someone criticises the Russian Government ie Putin, and then that someone dies by a radioactive isotope of Polonium that has a halflife of a few months, this stuff cannot be stockpiled for very long and it needs to br produced by a reactor. I don't think the ex-KGB agent was willing to die so that he could frame the Russian government for his own murder, religious fanatics do stuff like that, not usually Russians

Oh dear lord, please don't tell me you bought that hook, line and sinker, at least based on what is publically known.

Theres lots of reasons to dislike Putin, ranging from his attitude towards NGO's in Russia, to opposition to meaningful enforcement of international law in Iraq, Iran, and North Korea. None of that tops the need for America to have its own access to manned space flight for its own reasons.

#3754 Re: Human missions » Moonbase and Mass drivers etc etc » 2006-12-13 01:13:11

We should have realistic expectations for the immediate future, but we should also try to push the envelope as well

Three million tonnes of Lunar aluminum and glass are "not realistic" and are so far beyond "the envelope" that even talking about it with expectation of it coming about is crazy. You would have to able to mine, launch, capture, and mill 1000MT Al/SiO2 per day to build even this small O'Neill colony in eight years.

In the book Island One was compared to the Queen Elizabeth II with the point being made that it would have a similar mass to that ocean liner. So we do make objects with a mass of 3 million tons. And why not talk about it, don't they say that talk is cheap? As for the production capability, well we must build our way up to it of course and before that happens we build smaller things.

Its not okay to start talking about this scale of a project yet, nor any time soon.

And I say again, why not, talk is cheap and people talk about starships, which are surely much harder to build than these O'Neill colonies. People also talk about stockpiling and storing antimatter to be used for propulsion and that's way harder than an O'Neill colony, there is talk of building giant lasers to propell laser sails to the stars, all these things are further away than O'Neill colonies which are simply large structures in space.

A Lunar colony is not a good idea, despite putting it in a crater you are still vulnerable to 1/2-1/3 of the cosmic rays that come from every direction in space.

The Earth receives cosmic rays that come from all directions of space too. How many cosmic rays that are received by the colony would depend on how recessed the colony is into the Moons surface, it is is recessed enough, then the cosmic rays can only come from one direction, directly above the colony.

Mirrors would be no good either, that the total brightness they could reflect is limited by the brightness they receive, and placing a small area of them on the rim of the crater will make it awfully dark in the colony.

So? I didn't include the condition that the area of mirrors be small, and mirrors don't need to be of glass either, a shiny reflective sheet of aluminum would do just fine. The mirror would of course be flat, and it would be in the shape of an oval. The oval shaped mirror would be held above the colony dome by a  light weight tower with spindly legs mounted on a circular track surrounding the dome. The oval shaped mirror is held above the dome at a 45 degree angle so that it catches the horizontal sun rays and reflects them downward, the circular track allows the mirror to track the Sun as the moon rotates. The mirror always faces the sun and reflects the sunlight downwards into the dark crater where the dome is situated. If "night" is desired then individual segments of the oval shaped mirror are rotated 45 degrees so that their edges are oriented towards the colony dome, such that each segment reflects the light back at the Sun instead of down on the colony. When the mirror is looked up at from directly underneath it appears circular due to its 45 degree tilt. When the mirror segments are oriented edge on toward the colony, the onlooker would see the mirror framework and the stars shining through the individual mirror panel frames. Unlike on Earth when you build tall towers, on the moon you don't have to worry about windloads on the cross section of the tower or the mirror. The tower can be made light weight and just strong enough to support its own weight and the weight of the aluminum mirror it holds directly above.

A large dome capable of housing 10,000 people would also be quite huge and difficult to construct from Lunar glass. The gravity is also perhaps too low for humans to have and raise children, if these children ever wanted to return home to Earth (which many of them undoubtedly would), even Mars is iffy in this respect.

The population of a Lunar colony would likely be transient, people would tend to come and go, and what you said about Lunar gravity is also a good argument for O'Neill colonies since those can be made to provide Earth level gravity environments.

Another thing that you don't understand is that the total population of humanity is not going to increase forever at a very rapid pace, and will in fact probably level off at around 9Bn. We don't need the extra elbow room of a space colony any time soon, and maybe even never.

You can't predict at what level the population will level off at, that is a result of individual decisions about whether to have children. Humans have historically always filled in their living space, if more living space is provided, they are likely to have additional children to fill that in as well. If you are so down on space colonization, then why bother to talk about manned space travel at all, you could live in a world where everybody stares down at their feet all the time. The whole point of space travel is to expand the range of habitats humanity can inhabit, I really don't see any other reason for people to travel in space.

Random space dirt for ship radiation shielding is an awful idea because if your ship is too heavy, it takes too much rocket fuel to get anywhere.

Do you know what a cycling orbit is?
It is an orbit that takes the ship from the vicintity of Earth to the vicintity of Mars, and the gravity of Mars bends the orbit path just enough to send the ship back to Earth, whose gravity bends it juist enough to send in back to Mars again and this cycle is repeated over and over again with very little or no propellent expended. A cycling spaceship doesn't require much in the way of rocket engines to maintain its cycling orbit. You could have lunar rock placed around the cycling ship as it cycles around in its orbit, more and more lunar rock can be added with each passage close to Earth, until the cycling spaceship has a thick coating of rock that can block just about any type of radiation due to its sheer bulk, even secondary particles caused by cosmic rays hitting rock can be blocked if there is enough rock underneath it, and since rock is plentiful on the Moon and water is scarce, you use the rock. The rock needn't be processed overly much, a simple net can hold the stuff onto the spaceship, passage ways can protrude outside the layers of rock so that other ships can dock with the cycler.

Tom you make too big of a fuss...

...since the ISS is worthless. If the Russians backslide so much that we can't politically stomach sending up astronauts on Soyuz, then the solution is just to pull the plug on the station entirely. And if not for the ISS, then there is no rush to replace Shuttle.

That would save quite a bit of money that would then go to the Moon/Mars programs.

Screw the ISS

On the political side though, if we don't have something to show for the ISS effort, how can we then pursuade Congress to fork over money for Manned Moon/Mars missions? If its going to be an internationa space station, then its going to be one. I'd like to use the ISS as an incentive to hurry up on the CEV construction, having the Russians monopolize access to it, could be a good pursuader to get more money from Congress. Our resources aren't really stretched to the limit here, all we really need to do is provide Congress with a good reason to put up the extra funds, that Putin is a dictator, and is assassinating people could provide impetus to accelerate things.

#3756 Re: Human missions » Moonbase and Mass drivers etc etc » 2006-12-12 11:57:16

I think that there is a fundamental disconnect between whats reasonable and what you want to see happen Tom

The O'Neill space colony was conceived back when Shuttle was promised to be this all-singing/all-dancing super-cheap space truck, and back when building big space stations from little parts seemed like a good idea. Neither of these is the case.

To paraphrase my saying that some have adopted as their signature, you have a problem with really grasping decimal places I think. An O'Neill colony is estimated to require three million tonnes of Lunar aluminum, glass, etc and ten thousand tonnes of materials from Earth that can't be fabricated elsewhere. And thats only got room for 10,000 people. If you are talking about moving significant portions of people off the Earth, 10,000 at a time out of seven billion isn't going to get you anywhere.

Yes, those are large numbers, and it tells you how far we still have to go, but I think we shouldn't shrink those challenges. We should have realistic expectations for the immediate future, but we should also try to push the envelope as well. If we want to settle the Solar System, I mean really settle it, we need something like an O'Neill colony. If we just live in tin cans launched from Earth, our ability to live in the Solar System as a society is going to be very limited. Having a handful of people living on the Moon and Mars is a start, but we should not stop there.

I have no expectation of building an O'Neill Colony instead of going to Mars. I believe Mars is a step along the way, not directly of course, but we do have to improve our capacity to get into space to get to Mars and the Moon.

A Moonbase at the Pole could be very much like an O'Neill colony eventually, if we keep on expanding it, then eventually it could house 10,000 people just like an Island One Colony, it would not rotate for gravity of course, but we could build a dome in a crater with an equal land area to one. We'd start out by placing modules on the Moons surface and gradually as the population increased, we'd be able to specialize more and do some construction out of native materials - one of the requirements for building an O'Neill Space Colony. Being sited on the Pole, such a colony would not have to deal with a month long day/night cycle, it could sit in the shadow of a dark crated protected by the Moon's surface from Solar flares and partially from cosmic rays. Mirrors could then reflect the horizontal sunlight straight down into the colony provising light for agriculture. I suppose the mirror or mirrors would have to be light weight and mounted on a turntable so as to track the Sun. A lot of little mirrors would probably be easier.

A polar Moon colony can just as legitimately be called a space colony as would an O'Neill settlement. One possible use for moon rocks, would be as a radiation shield for a cycling spaceships between Earth and Mars. If you pile enough moon rocks around an space ship, you will have an effective radiation shield.

Oh, and tugs using electric fields to push off the Earth's? Uh, the Earth doesn't have an electric field. Try a MagSail instead.

The Earth does have a magnetic field it is this that is used to repel a tug from LEO to higher altitudes and it can then attract itself back down to LEO.

Electrodynamic Tethers: Getting into the Swing

It is not a fast system but it does benefit from simplicity.

-On the equator of the Moon, you only get about one week out of the month of peak solar power when the Sun is overhead. Maybe stretch it to 10-11 days with gimbaled panels, but thats extra trouble. Since a railgun will be power hungry, this is the worst-case time you would have to operate the thing.

The solution is simple using our plans to create automated solar cell production we then build solar cell farms to the west and east and connect by buried cables then keep going to increase power supply to the point we actually are working. At the lunar poles it makes sense with the horizon being so close and that we then we will have almost constant power supply. The lifeblood of our space exploration. And when we move to another point we simply connect into what will be a quazi lunar power grid. When we leave the poles to go to the equator we do the same there and connect to the poles.

I think we should at least give the idea of O'Neill type space colonies a thorough study. How close are we those capacities, and how much closer are we than the 1970s when they were proposed. the Ability to build an Island One or a Stanford Torus is the first step in the construction of manned Starships, we should try to develop a space construction capacity for that reason. Presurvation of the Human Race is another reason. Humanity remains vulnerable if it is stuck on one or two planets. Mars colonies ought to be easier to get started as they can start small, but we shouldn't stop there. Inhabiting space ought to reduce our concern with the global environment, since we won't be living on a globe. This greap leap into space has been tougher than anticipated, but I still think we should make the attempt.

#3758 Re: Space Policy » NASA 2008 Budget » 2006-12-12 09:43:29

Actually the solution is one that tastes bitter in that we can buy the seat during the laps of any US vehicle for manned use. It is cheap and does allow for continued US manning of the US but it comes with a price.
I think that price will be a few seats to the moon and probably ending with cash to build a few of the needed items for the moon base.

I don't want US Astronauts to have to fly Putin Spaceways. Our partnership was not initially with a dictator. Since we have time to accelerate the Orion Program, as Russia seems unstable, we should, and not have to face the problem of no manned space vehicle.

BOEHLERT ASKS Office of Management and Budget (OMB) FOR ADDITIONAL SCIENCE FUNDING IN FY 2008, STRESSES IMPORTANCE OF American Competitiveness Initiative (ACI).

I hope your fiscal 2008 requests for the National Science Foundation (NSF), the Department of Energy (DOE) Office of Science and the National Institute of Standards and Technology (NIST) will be at levels appropriate for a second year of ACI implementation.

NASA needs additional funding if it is to move ahead with both the Vision for Space Exploration and the space science, earth science and aeronautics research required by the NASA Authorization Act of 2005. 

There is no reason to launch the Orion Crew Exploration Vehicle before 2014, and there is every reason to retire the Space Shuttle in 2010, as planned.


Geee no reason to close the gap...

I can think of one good reason. Vladimir Putin! I don't want to have to depend on him for getting to the Space Station! I don't like the fact that he goes around ordering the assassinations of Russian citizens in foreign countries using Polonium 210. If Russia is going to act this way, I want to decouple our Nation;s space Program from his. I think the construction of the Orion should be accelerated to make it available as soon as possible, if this requires extra funding, then so be it. Ideally it should be available at or before the Shuttle's decommisioning so their are no gaps and we don't have to depend on Russia with not independent manned space capacity. The CEV doesn't look like that hard a vehicle to build, if we built the Apollo, the Orion should be a piece of cake.

#3760 Re: Not So Free Chat » Why does U.S.A. support Israel? - Finally, I'm Asking » 2006-12-12 02:16:23

My feeling is that so long as Palestinians continue to kill Jews, the Israelis have no obligation or reason to listen to them, let them stop first... Seems perfectly reasonable not to talk to someone who's trying to kill you.

Palestinians say the same thing. Failure to listen is why they've been fighting over the same piece of land for thousands of years. They left Israel for the Nile delta, came back (the Exodus), the northern kingdom called Israel was conquered by Assyrians, the southern kingdom called Judah (hence the name Jew) was conquered by Romans, and all the rest. Through it all Hebrew and Arab have been fighting since Joseph and Ishmael. The fight was old when a teacher named Jesus of Nazareth was born. He taught tolerance and non-violence. Sound familiar?

Your accusation that Canada is dominated by Muslims is tiresome. If you were to draw a conclusion from those statistics, you would claim Canada is a purely Christian country, neither Judeo- nor Islamo- anything. Truth is Canada today has many religions.

If you really want to know, Canada learned the need for religious tolerance the hard way. It wasn't always this peaceful. From the Canadian Encyclopedia:

On 6 June 1853, Alessandro Gavazzi, a recently arrived Italian patriot, gave a speech in Québec City at the Free Presbyterian Church. A riot resulted, the principal participants being Irish Catholics who reacted violently to Gavazzi's anti-Catholic sentiments. Gavazzi attributed the failure of the Italian national movement of 1848-49 to the defection of Pope Pius IX from the cause, and therefore rejected Catholicism. On June 9 he repeated his diatribe at Montréal's Zion Church. In the following riot, the police lost control and Mayor Charles Wilson apparently called out a detachment from the local garrison. The soldiers opened fire, killing 10 and wounding 50. The riots caused by Gavazzi's incendiary preaching in Québec and Montréal illustrate the instances of religious fanaticism that occurred frequently throughout the 19th century.

Our tolerance for fanatics blowing themselves up, or crashing airplanes into our buildings while they practise their religion is rather low. It would be one thing if Islamic terrorism was a fluke, but just tune in for the latest suicide bomb attack in Iraq and you realize that its not. If it was a fluke it would not be so common, but since thousands of US soldiers have died from religious Islamic fanatics blowing themselves up, there is something wrong with that religion for them to allow such a thing, and I certainly don't want to roll out the red carpet for them so that there will be more of them to blow themselves up and kill more Americans.

Also if Iraqis can't tamp down their violence in Iraq, and are unready for democracy, then I don't want them in my country ruining what we have here. I prefer Islamic terrorism to be an Islamic problem, I don't want to make their problems my problems. Its too bad mainstream Muslims have allowed their religion to gain a reputation for suicide fanatacism, they have failed to condemn it in sufficient numbers and they complain too much when we fight Islamic terrorism.

#3761 Re: Human missions » Moonbase and Mass drivers etc etc » 2006-12-12 02:08:09

My I have gotten behind, where to begin:

  • -Solar rockets, I mean their thrust compared to chemical or nuclear rockets is almost nil. You can't get off the ground with a solar rocket, even off the Moon.

    -Mass drivers to Earth are not a good idea if for no other reason than the Earth will be out of alignment for the shot except for a small fraction of the month. This breaks the usefulness of "many smaller payload" method. The only place such a gun should be aimed is a LaGrange point, where you wouldn't need orbital circulization. This is probably the only good way to build an O'Neil style colony, though I don't think those things will ever become very popular. Its going to be an extremely long time before we'd need the room I would think.
    .

A few things can be said for O'Neill type colonies.
1) They have more volume per given surface area and thus provide more shielding per inhabitant per unit mass than a small space colony.
2) O'Neill colonies can provide Earth normal "spin gravity" and you avoid the problem of humans adapting to lower gravity environments with weak bones, weak muscles, and a weak cardio-vascular system.
3) O'Neill are better at simulating a natural environment than a "tin can" habitat. They provide little bits of Earth away from Earth, and provides the feeling of being outdoors rather than being either indoors or in a spacesuit fogging up the face plate and unable to scratch your nose.

#3762 Re: Not So Free Chat » Why does U.S.A. support Israel? - Finally, I'm Asking » 2006-12-11 09:52:11

Tom, you keep holding onto the belief that "might makes right". You think that winning is everything. That's the primitive, animal belief. The ability to build things and the ability to work together as a team is what separates humans from animals. The attitude of destroying everything and constantly fighting with a winner and a looser is the attitude of a predator. If you are so obsessed with winning, then you're not human, you're just an animal and deserve to be treated as an animal. Have I gotten sufficiently insulting? Are you going to listen now? You didn't listen when I tried to explain things calmly.

Who is to be the arbitrator of "Goodness"? Certainly not the side supporting the terrorists, the one sending out suicide bombers into crowds to go blow themselves up. Israel does not send Suicide bombers and never has, by that measure it values human life more and is thus the default "good" side. Is it your intention to dwell on the Good versus evil debate in order to parayze people from defending themselves from terrorists? Do you want them sitting around thinking, "Do we deserve to survive? Perhaps we don't? Maybe we should just let them kill us?" Maybe you have doubts about whether the Israeli Jews should survive or their children, or whether the Israelis shoulc defend their children from Palestinians suicide attacks, or missile attacks across the border, but they don't. Franky your argument about whether the Israelis should allow the Palestinian terrorists to kill their children and not take all measures to protect them is not very persuasive. Are you trying to convince the Israelis to allow their children to be murdered because of some past history, and that maybe the Palestinians have a "right" to kill them because they were unlawfully deprived of their land.

My feeling is that so long as Palestinians continue to kill Jews, the Israelis have no obligation or reason to listen to them, let them stop first, and then lets discuss what's right for the Palestinians and arrive a some sort of compromise. clearly the Jews need the land more than the Palestinians, as the Palestinians can live alot more places than the Israelis can. If the Palestinians start killing again then the talks cease. Seems perfectly reasonable not to talk to someone who's trying to kill you.


If you are so committed to the delusion that one side is "good" and the other side is "evil", and you aren't going to listen to the facts, then again you are just an animal. Throwing out an accusation that Canada supports terrorism because we won't persecute Muslims, simply demonstrates the depth of your ignorance. I got the figures from Census Canada's website; they're published in numbers of individuals, I calculated percentage by dividing by the total number of individuals in Canada from the same table. The number of people of the Jewish faith as opposed to Muslim has nothing to do with any bias; it's merely the number of individuals in the world who belong to those religions. Canada welcomes everyone, but does insist that everyone assimilate the Canadian values of tolerance, acceptance, religious freedom, and non-violence.

The percentages of minorities influences foreign policy in a democracy, so instead of having Judeo-Christian values, Canada has Islamo-Christian values. Islamic values on the whole are illiberal and intollerant, and if Canada is not careful it may go from a liberal democracy to an iliberal intollerant one by tollerating intollerance. Canada has a small population, and if equal numbers rather than percentages go to both the USA and Canada, guess what's going to happen.

I think Canada is often the place for Muslims pursuing the "American Dream" but hate America so much that they are looking for an alternative. Canada for them is almost the USA, but without those "annoying" Stars and Stripes, and without the Superpower status, and nice humble "little USA" is what they want for pursuing their "American Dream", and if the want to kill some USA Americans for the "latest outrage" in foreign policy, they can just skip over the border.

And don't even try to throw out the old accusation that terrorists come from Canada. Some congressmen attempted to blame Canada for 9/11. I already pointed out that there was only 1 terrorist cell arrested in Canada, and that cell was founded and led by an American. And that American was determined to be loudmouthed by harmless by the FBI. He moved to Canada after the FBI detained him. The group was arrested with ammonium nitrate fertilizer, but the RCMP had to help them get even that. None of them had the agricultural certification necessary to purchase that fertilizer, only the RCMP infiltrator had it.

But you raised Poland and France. These countries were conquered, subjugated, and occupied by the Nazis. There were many Polish nationals exterminated in the camps as well, and France fought against Nazis until they were free. I don't think the Jews have anything against them. In fact, many Germans disagreed with the Nazi policy of exterminating Jews, but were afraid to act for fear they would be exterminated as well. The Nazis exterminated Serbs, homosexuals, as well as Polish and Soviet prisoners of war. 80% of those killed in the extermination camps were Jews, but don't think Poles hated Jews after so many Poles were exterminated too.

There is some overlap between Poles and Jews, since most of the Death Camps were built in Poland. Many Jewish Poles died in those camps. Whether its the Poles fault is irrelevant, the Jews didn't feel safe their and the Communist Authorities encouraged them to leave afterwards, alot of them moved to Israel. The problem with Jewish minorities in other countries is that they aren't allowed to form their own armies in their own self-defense, and as an independent Nation, they can. The Non Jewish French did not fight the Germans all that hard, since they knew only the Jews had the most to lose. I'm sure that of France was 100% Jewish, the Germans would have had a much tougher time conquering the place, as they would have had to exterminate every Jew in every population center and since no mercy would be given to any Jew that surrendered all would fight to the death. Most non-Jewish French soldiers surrendered, because they figured the Germans would let them live, and by their surrender they exposed the Jewish minority to the danger of extermination. The Jews thereby realized that they couldn't depend on their non-Jewish fellow citizens to defend themselves against a foreign enemy that wants to exterminate them, that is how I figure Jews would be safer in Israel where you have Jews defending Jews and they are all in the same "boat".


Nazi prisoner badges (Wikipedia)

The most common forms of the badge were:

Black inverted triangle
• The Mentally retarded
• Alcoholics
• Vagrants, the Habitually "Work-Shy".
• Roma and Sinti (later forced to wear the Brown Triangle).
• A woman jailed for "anti-social behavior", i.e., a lesbian, a prostitute or woman who used birth control.
Green inverted triangle — criminals.
Pink inverted triangle — a homosexual or bisexual man.
Purple inverted triangle — Jehovah's Witnesses
Red inverted triangle — a political prisoner. Social Democrats, Freemasons, anarchists (some anarchists were also given the black triangle), and other "enemies of the state". The color red was probably chosen because it represented the communists, the political enemies that the Nazis hated most (and the first to be officially outlawed).

Double triangles:

Two superimposed yellow triangles forming the Star of David — a Jew, including Jews by practice or descent.
Pink inverted triangle superimposed upon a yellow one, making the Star of David — a homosexual Jew.
Yellow triangle superimposed over a black inverted triangle, or "voided" black inverted triangle superimposed over a yellow triangle — an Aryan convicted of miscegenation and labeled as a "race defiler."

Miscegenation means interracial marriage. Don't think the Jews were the only ones badly treated. Even many Germans today are ashamed of what the Nazis did.

And none of this excuses what the Israelis did once there were in Israel. Two wrongs do not make a right. Notice I use the national term, not the religious one. There is a difference.

In other words you are asking Israelis to give up their citizenship and immigrate to other people's countries, where they are more vulnerable to extermination and their fellow non-jewish citizens may be less interested in defending them. You see in order for the French to fight to protect the Jews the way other Jews in Israel would, they must all be willing to fight to the death, the French weren't willing to be exterminated along with their Jewish minority, so they surrendered, thus exposing the Jews to more danger by reducing the Germans workload in conquering France. There is no guarantee that further pogroms won't occur if Jews migrate to other countries where they will be minorities. Being a minority means that you are outnumbered by everyone else, and that you are discouraged from forming your own seperate Jewish army to protect yourself with, and history has shown that Jews need that protection, because of all the special efforts that were mounted at various times to kill them and to make them the scapegoat. I think the Jews have had enough after 2000 years of this, and it is about time they have their own country, the rest of the world really gave them no choice.

epocalypse please give post that list of modern IDF atrocities; Tom needs to see it.

There are American and Canadian Attrocities as well, does that mean that neither country has a right to defend itself. No country is perfect, and having higher standards that you expect the Israelis to live up to that you expect the Palestinians or yourselves is not fair, and it is a form of bias against Jews. I think the way the Israelis are behaving as a whole is a darn site bettet than the Suicide bomber Palestinians. Israel is giveing up land to them, the Palestinians aren't, they keep what they have and they get more and yet continue to kill Jews.

Lunar and Mars exploration aren't specifically addressed. I hope they don't insist on substituting a Gore Sat and calling it "Space Exploration". NASA has set the course, either we go to Mars fast or slow, depending on available funding. If there are truly any "John F.

You heard of the "many universe" model of reality. Everytime you flip a coin there is one universe where the result is heads and another universe where the result is tails. You get split in two along with the Universe as you flip the coin and each you is unaware of the other and each observes only on outcome of the coin toss and not the other. I'd say the probability of someone arriving from the future must be minutely small, since we don't seem people arrive from the future all the time. From the point of view of the time traveller, traveling back in time is simply winding back history and rerolling all the random "dice" of everything that occurs after you reenter the timeline. Even if the time traveller does absolutely nothing and makes no contact with the world, and even if he is light years away and cannot possible effect anyting on Earth, events may still transpire differently, since different atoms may decay at different times from what happend before, the random atoms will travel in different directions as a result, different weather patterns will arise out of this, and on days that were previously sunny in the original history may experience rain in the new timeline. A time traveller who went back in time could never return to his future.

Time Travellers can use their knowledge to their own benefit, certainly the short term plans of the major political actors will be know to them and their actions anticipated from that over the short term. Superior technology would be great help. If the time traveller were to take a series of short hops back in time frequently, he could literally create a timeline where there was no wars, simply by the expedient of going back in time and eliminating those who would have started them.

You could go back in time and get rid of Hitler, and go back in time and eliminate those who would have filled the power vacuum and would have done bad things. The easiest thing to do is just send Adolf back in time and thuis into another reality where in the one he left he is never seen again.

#3766 Re: Human missions » How much the return to the Moon and Mars-trip costs ? » 2006-12-11 01:42:26

In order for the Moon base to have a final price, then at some point in the future the Moonbase will have to be abandoned, so the bean counters can tally up all the expenditures that accrued while it was in operation. The only reason we can come up with a dollar figure for the entire Apollo Program is because it is not ongoing. I think ideally NASA should have enough money in its annual expenditure to operate both a Moonbase and a Marsbase at the same time, and as the US economy grows, so does NASA's budget, and technology will hopefully reduce costs allowing NASA to establish other bases elsewhere in the Solar System. Eventually these Installations should pay for themselves though and NASA will move onto other things such as Starships.

How much for a moon base?
http://www.msnbc.msn.com/id/16126918/
Don’t ask

Avoiding sticker shock
This way there are not the massive budget overruns that have forever dogged the international space station, which was once projected to cost $17 billion but is actually in the $50 billion range, McCurdy said. It also avoids the sticker shock of a $500 billion moon-and-Mars program proposed by President Bush’s father that collapsed when the cost was revealed.

But Taxpayers for Common Sense, a fiscal watchdog group, calls the moon plans a waste.

I don't think there ever was a time when Congress wrote a single big check for the Entire Apollo Program. Money was appropriated for each year that the Apollo program ran, the same would be true of a Moon base.

The cost of the entire Moonbase program would be a function of how long we continued to operate the Moonbase. If its for a long time, then it will cost more than if we operated it for one year.

Case 1: Suppose we build a Moonbase in 2020 and then abandoned in it 2021 How much would that costs?

Case 2: Suppose we build a Moonbase in 2020 and then continued to operate it sending astronauts their and expanding the Moonbase with time until it grew into a large community with tens of thousands of people by the year 2100, how much would that cost.

Any bean counter would conclude that case 2: would be more expensive than case one, as it would require that the Moonbase be expanded to accomodate tens of thousands of people and be operated for 80 years. Surely it would be cheaper just to establish the Moonbase in 2020 and abandon it the next year to save money.

What do you think, is there something wrong with this reasoning?

#3768 Re: Human missions » Is the 'VSE' getting dimmer ? » 2006-12-10 10:56:54

Some negative press from the anti-manned space flight lobby

Don't colonize the moon
http://www.latimes.com/news/opinion/la- … n-leftrail
A manned moon mission doesn't make sense.

Why do anything? I'll net the LATimes would be happy if the US does nothing but contemplate its navel.
The Moon is a foothold into space and Mars is another one.

It would be easier to establish a colony on the Moon, the Moon is closer and our access to the Moon is contiuous, not like Mars where we have to wait for launch windows. People living on the Moon could have phone service, access to Satellite Television and the Internet with near realtime communication with Earth. All you can do on Mars, is send and receive e-mail, voice-mail and video-mail and wait for it to arrive. Martians have to wait for the planets to align properly before making any trips to Earth or to receive any visitors from there. The Moon is the nearest continuously available exterestrial body available for mining. Mars would provide a good roll as a supplier of hydrogen and other volitiles for the Moon. The problems of exposure to radiation and long travel times are less for trips to the Moon, and we can get their with relatively off-the shelf technology more or less derived from our Apollo experience. The Moon would open up the gates for Mars, as it would require us to develop launch technology that would be useful for the trip to Mars.

I don't see how we can just ignore the Moon and head directly to Mars. I think both activities compliment each other, and if we are forced into a choice between the Moon or Mars, our grip on either one would be tenuous at best.

#3769 Re: Not So Free Chat » Why does U.S.A. support Israel? - Finally, I'm Asking » 2006-12-10 09:07:08

Do you really expect a Jewish person who had most of his family decimated in the Holocaust to go on living in Poland, Germany, or France as if nothing has happened? Wouldn't you expect his faith in his ability to exist in someone else's country as a minority to be a little shaken? That's why they need an Israel. Most of those other minorities in Canada didn't have extermination programs against them, and on top of that there are people who question whether Israel has the right to exist, and are rooting for the Palestinians, and Jewish people whose families came out of the holocaust are supposed to trust them? Of all the minorities there, the Jews have a demosratable need to have a country of their own, because the rest of the world just won't stop killing them or calling for their deaths. You expect them all to just shrug off the holocaust as if it was nothing special or no big deal?

I also note that Muslims outnumber Jews almost 2:1 in your country by your statistics. Canada has really rolled out the welcome mat for Muslims it seems, and you know how most muslims feel about Jews. I think some of the more recent Jews arriving in Israel may come from Canada.

#3770 Re: Interplanetary transportation » Warp Drive » 2006-12-10 08:56:48

If time travel was to happen what would it mean? Where are the travels from the future? There are three kinds of processes that we can easily understand, causal, non causal and anti causal. Non causal means event happen not only based on passed events but future events. A perfect low pass filter is a non causal filter. If there we people or particles traveling back in time it is well beyond our comprehension today how that could result in one reality. Of course do we have one reality. With special relativity two observers cannot agree on the order of events anyway.

What if there were 10^100 different realities splitting off from a single point in time and just one of them happened to involved a time traveler arriving from the future at just that precise moment. What would the chances be of our reality being the same one with that time traveller in it? Maybe history is always splitting off anyway, whether time travel is involved or not and if someone goes back in time, the point where the traveler reenters the timeline occurs in just one of those realities.

The Time traveller would arrive in some point that appears to be the past, but would then find events unfolding differently from the moment he arrived. This model of time travel preserves free will and everything is random even if you travel back in time.

#3771 Re: Not So Free Chat » Why does U.S.A. support Israel? - Finally, I'm Asking » 2006-12-09 15:04:42

I am a British jew of Polish stock.  I am not a zionist.

I think you should try getting facts straight before launching into racist tirades.

But since we will have plenty of Jews going to Mars are there any creeds, colours or viewpoints you will prevent going to Mars.  I think we already know your opinion on the Chinese.

Do you know what happened to most Polish Jews? There used to be a Jewish Community in Poland, the Jews thought of themselves as Poles, and then the Germans came, and murdered most of them, men women and children, and on those sites where many of the Jews lived, they turned into Ghettos or Death Camps, and then they shipped over Jews who thought they were German and exterminated them, they shipped over Jews who thought they were French and Exterminated them, and Jews from Russia they exterminated, even Jews from Italy went up in smoke, that was when alot of Jews figured that being a religious minority in someone else's country was not a good idea and it was the impetus for establishing Israel. You are only lucky that the Germans didn't succeed in conquering Great Britian, then British Jews would have joined the French, German, Russian, Italian and Polish Jews in the gas chambers. Maybe you feel safe in Great Britian, but you must know that the political winds can run foul for Jews their too, and their is an influx of Muslim migrant workers, and they have more children than native Brits, they may turn against you in their Israel bashing, no doubt about that. Palestinians kill jews, just like the Germans did. The Jews that end up dead as a result of Palestinian suicide terrorist attacks are just as dead as the ones that died in the gas chambers during World War II. I remind you that it might not be a good idea to join in a political movement which may turn against Jews, just as National Socialism did. I've already seen how the Democratic Party abandoned Senator Joe Liberman because he was a Jew.

All this anti-Israel bashing is a wedge issue, it serves to make antisemitism more acceptable in mainstream society. If people see others burning Israeli flags and saying, "Death to the Zionist Imperialists." Someone else may start flying swastikas and start saying, "Death to the Jews!" and once they start saying that and that sort of politics becomes more acceptable, then things will start happening to the Jews like the did in the 1930s in Germany and later in the rest of Europe. The Germans are the father of Israel more than anyone, it was they who demostrated the necessity of Israel's existance, and unless you can erase World War II and the Holocaust from History, Israel should remain.

#3772 Re: Not So Free Chat » Why does U.S.A. support Israel? - Finally, I'm Asking » 2006-12-09 10:09:14

it wasn't Israelis that voted terrorists into their government, if they did, we'd know about it, believe me!

Just a short list of former Zionist terrorists voted into high office in Israel;

David Ben-Gurion, Haganah but did much to disband Zionist terrorist groups
Yigal Allon, Haganah
Yitzhak Rabin, Palmach
Menachem Begin, Irgun
Yitzhak Shamir, Stern Gang, Lehi (an acknowledged admirer of the IRA)


And out of interest the terrorism did not stop with the founding of Israel.  Menachem Begin and Irgun attempted to assasinate Konrad Adenauer, German Chancellor, in 1952 to scupper reparation talks between Israel and Germany.

You can continue to cherry pick Jewish badguys to make your case, Begin is not Prime Minster of Israel now, and neigther is Adolf Hitler the Chancellor of Germany. You have to blow off the dust and the cobwebs off those old Israeli terrorist cases, and I just have to read today's newspapers to fing the Palestinian ones. Palestinian terrorism is an ongoing phenominon, while Jewish terrorists are a footnote in history. The Palestinians have concentrated on killing as many Jews as they could, now think of what the Israelis might do with their capabilities if they had similar goals with regard to the Palestinians? Hamas launches rockets full of pellets into Israeli town hoping to kill as many innocent people as possible, attempting to assasinate Konrad Adenauer is targeting of a specific person, it wasn't as the Palestinians are attempting, to kill as many of a certain category of people as possible. Palestinians weren't trying to kill anyone specific in launching their rockets, their target was Jews in general, not some general or some prime minister, that is my definition of terrorism, totally divorced from military goals and only seeking to kill innocent people. Killing a head of state is an act of War. If Israel wanted to wage war on Germany, then killing its political leader is a perfectly legitimate target, but killing civilians unnecessarily is not. I don't know what political leader or military target Hamas was aiming for when it attacked those Israeli villages with missiles loaded with buckshot, seems their only goal was to kill Jews, and that meets my definition of terrorism.

By the way, what are you trying to do? Drive all the Jews out of the Mars Society? So much Jew Bashing going on here. I'm sure their are also plenty of Jews interested in Traveling to Mars, it would be nice if you could be more open-minded.

#3773 Re: Not So Free Chat » Why does U.S.A. support Israel? - Finally, I'm Asking » 2006-12-09 09:56:21

God, Tom pick up a history book or something.  The King David bombing was in 1946 by Zionist terrorists led by Menachim Begin, a man who became Prime Minister of Israel.  If you want me to reel off a list of modern IDF atrocities I will and as counterbalance I'll give a list of Palestinian ones too.

During the run up to the foundation of the state of Israel Jewish terrorists murdered, kidnapped and tortured hundreds of civilians and unarmed British soldiers.  The leaders and many members of these terrorist organisations, Irgun, Lehi and to an extent Haganah became the leaders of the new state of Israel.

I will not condone Palestinian outrages but nor will I listen to your holier than thou bollocks.  Fact is fact, the state of Israel was founded on terror by terrorists and your refusal to accept this shows you to be a hypocrite.

And who has killed british citizens lately, not nearly a century ago? What about the London Subway bombings, it wasn't Jews who did that? There were bad Jews in Israel's past, so? There were bad Americans who helped expand America's borders. All I really want is for Palestinians and Arabs to stop murdering innocent Jews now! What you talk about in the King David Hotel is ancient history as far as I'm concerned, what you are talking about is practically the World War II generation. I am not supportive of people who kill Germans or Japanese citizens and then use the excuse that the Germans and Japanese were responsible for attrocities in the past, and I think the Israelis should be given than same benefit. The fact is the Palestinians are murdering innocent people now, and as long as they continue to do that, they should be given nothing. I do note that the Israelis did stop murdering British citizens a long time ago, have the Arabs?

#3774 Re: Not So Free Chat » Why does U.S.A. support Israel? - Finally, I'm Asking » 2006-12-09 09:03:54

So if they are not all Saints they are all villians, is that what your saying? But think about it, only 91 people? Surely with the formost military in the Middle East they are capable of killing much more than 91 people in a bomb attack. The fact that the Palestinian population is growing so fast, indicates that they are not killing as many civilians as they could, you see Israelis control the Palestinian space and they don't maximise the slaughter, yet the Palestinians don't control the Israeli's space and they do their best to kill as many Jews as they can, that is what I mean by terrorism. If a few Jews murder a few arabs, you can't paint the whole of Israeli with a broad brush as that does not constitute Israeli policy, it wasn't Israelis that voted terrorists into their government, if they did, we'd know about it, believe me!

#3775 Re: Interplanetary transportation » Warp Drive » 2006-12-09 02:34:52

No but it is good if that universe he helps is ours.

I wonder about universe 'sets' where time travel twins off not just one bubble--but many more involving the tampering.

urs doesn't seem to be one of those universes, but there is always a chance that random atoms floating around in space might suddenly come together in their random motion and form a "time machine with an astronaut on board". the probability of that happening is not zero, just very very small. The probabilities might be similar for receiving visitors from alternate futures whose pasts do not have visitors from the future.
