What about the "missing mass" of the universe that is called "Dark Matter? I heard that some people are doing an experiment to prove whether or not dark matter is passing through solid rock on our planet. I heard also that they are calling this dark matter "WIMPS". Why are they calling them that?
"As the respective sets of equations are based on the two pillars, so too are the pillars utterly different from each other, as starkly contrasted as columns Ionic and Corinthian"
I also agree that the two pillars are very different from each other. Would those pillars be quantum mechanics and general relativity? Those two pillars can't be easily unified. How can a gravitational field exist in a gravitational well?
"The aether probably is not a fluid so much as a fabric, and probably a fabric that is very, very hard to tear. "
I'd like to see some proof that the so called "aether" is real. In experiments preformed in the late 19'th and early 20'th centruies, physicists have not had any successful experiments saying that the "aether" is real. I'd like to see more sofisticated expermiments done to try to prove that it is real.
Boundaries between different colonies will eventually not have that much importance because the different colonies might eventually develop an internet like we have on earth. What would the potential impact be on the future martian colonies? Could the government be run using computers connected to the internet and different representatives from different colonies meeting online? What about digital voting? Digital voting is already happening on earth. Eventually people won't need to leave their homes in order to vote.
"Controlled fusion doesn't even exist, outside of anyone's imagination. If you want to propose fusion as a means of propulsion, describe the fusion process you mean. I wish it weren't a pipe-dream, but that's all it is unfortunately."
If fusion power is not yet practical, then what about fission? Fission has been used for a long time in nuclear power plants. It's very easy to manufacture and I think that if there is a human mars mission, it could be manufactured on the martian surface and eventually used to get the crew back home. What if a huge short burst of kinetic energy from a fission reaction was used inside of some hole in the back of the spacecraft was used much like in the back of the rocket that could project the fission reaction towards the back of the spacecraft to get it go accelerate. The plutonium or uranium could cover the walls of the place where it would go out or it could be right next to it and the energy would go from inside the spacecraft toward to back and then outward.

They maintain that there are other explanations for how the universe works and that the speed of light is not the limit, gravity, for example, being thought by some to propagate at almost infinite speed.
At least twenty billion times faster than light, aye (vide supra)
How can anything go faster than light? I heard that if you go faster then light, then you go backward in time. Can gravity go backward in time if it propagates faster than light?
Will the Martian settelers eventually form nations on Mars or world governments on Mars?
Will anyone in the marssociety eventually search for intelligent alien life through either Radio Astronomy or Infrared Astronomy or Optical Astronomy?
Isn't gravity caused by a gravitational well and the fact that space is curved as said in the general and special theories of relativity? Would such a particle not exist if this was correct? Could a spacecraft somehow produce it's own gravitational well or enhance it to make the crew on board more comfortable?
Would a spacecraft that explodes small nuclear bombs inside a material that would withstand a nuclear explosion and release energy that would come out of the back of the spacecraft through some sort of hole actually work?
What about somehow using the magnetic field as a power source? Would that work? Even on Mars?
Is it possible to build a fission powered orion spacecraft that would explode the nukes inside of the back of the spacecraft and could it have an opening in the back of the spacecraft where all the kenitic energy could come out? Could a nuclear reactor be capable of producing one explosion after another with enough uranium or plutonium to power it?
If there is organic matter in venus' atmosphere, than a space probe should be able to test for it or scan for it somehow when entering venus' atmosphere if one ever did go there. I think that the probe could also pick up lightening on it's radio antennas if they were made sensitive enough.
When do you think anybody will actually build this stuff?
I think that the huge amounts of lightening in Venus' atmosphere are there because of the high amounts of sulfuric acid in the clouds and that chemical is what goes into batteries, so there could be a whole lot of nickle and iron on the surface because when you use a lemon battery, you use those metals to generate an electric current to get it to flow through the curcit. Acid is also in lemons and that can produce an electric current that flows through the wires of a homemade battery. Does any of this make sense?
Instead of a pusher plate, us a mag-sail to catch the high speed plasma from the explosion and away you go. Storing the anti-matter is also tough and producing the antimatter is also tough. We have quite a ways to go before antimatter propulsion is used.
Yes. But is it a good idea?
Ian, I'm aware of the efforts in Iceland to derive energy from their thermal fields, but that's the exception rather than the rule. I was thinking more along the lines of drilling deep wells in places where there isn't much geothermal activity (basicially anywhere), and making this a primary source of power generation, rather than oil, coal or nuclear...
Would it cost a whole lot of money to build such power plants and is the location of the power plant you referred to restriced by geology and would geology determine where such power plants could be?
I was just wondering. Could this be done on Mars to provide temporary power for a small landing crew for several months or a year rather than nuclear power?
I've been wondering...if it's so hot just a few miles beneath the surface of the Earth...why not drill some super-deep wells, pump water down in them, flash-heat it into steam and use it for electric power generation. It really can't be that hard with 21st century technology, can it?
Just think, if something like this could be made to work, we would have virtually unlimited energy at our disposal...without the negative effects of CO2 production or nuclear waste.
B
I think that that's already been done. It's called thermal energy. They drill a huge hole into the earth and they put pipes in and the steam that comes out of it turns electric generators and the turbines spin because of the kinetic energy released from the heat. There's also an idea to use the earth's tides to generate electricity. I think that's been experimented with too.
IAN-
While the Magnetic field varies slightly from place to place, not usually noticable on a standard compass, as long as your withing the magnetic field, and are not close to another magnet of some kind. So if you are in a cave, that is standard limestone(most caves are due to karst topography) your compass should still be accurate to magnetic north.
What happens when you go 50 miles down into the earth? What happens to compas needles when they go 70 miles into the earth? What happens to the compass when you go to the layer of the earth that people drill oil from or mine precious minerals deep in the earth? In Jules Verne's book Journey to the center of the earth, they talk about an n deviation in the characters' compass. What were they talking about?
Is there any indication that there was a magnetic field surronding Mars?
Is there any evidence to support the gaia hypothesis on earth or on mars? Is mars a dead superorganism while the earth is a living one? What kinds of theorys is the gaia hypothesis founded on and can the same be said about mars and the rest of the planets in the solar system?
I wonder what will happen to the earth once it's magnetic fields shift or run out. There's been a whole lot of research into what the earth's magnetic field looks like at the center of the earth. Has anybody ever taken a magnetic compass into a cave? It might show north and south in the opposite directions when somebody explores a cave and goes down really far. What does Mars' magnetic field look like? Is it too losing it's energy or power like the earth's magnetic field? If so, can someone do some sort of test to check out mars' magnetic fields? I would like to know what they look like.
Well once we have a good enough material to withstand the explosiveness of the antimatter, then we could focus the energy of the antimatter explosions toward the back and the ship will accelerate forward. It is probably possible to construct a material that won't explode when the antimatter explodes against that material. Then when we focus the antimatter explosions in a certain direction it will produce a thrust much like how a rocket produces thrust but much faster. The material that focuses it must be strong enough to resist antimatter explosions.
Can antimatter bombs be exploded behind a ship much like the proposed orion a bomb starship? The force coming from the energy behind the ship could in theory propell it to incredibly fast speeds, speeds that would be faster if nuclear fusion or fission was used to make a whole lot of kinetic energy. Could someone design such a ship that would make a whole lot of energy come out of the back of the ship or be exploded against the side of the back of the ship in order for it to accelerate to an extremely fast speed?
Have any if you seen mars or August 26th? I was in a hotel building when I saw it from the window in the hall. It was one of the brightest objects in the sky.
