#701 Re: Intelligent Alien Life » First Contact? - Something odd, at any rate » 2004-09-02 14:08:16

Whoa.  Behold the power of distributed computing!   cool

Personally, I don't see how the signal characteristics preclude an intelligent origin.  (How many human radio sources do you know of that adjust for the rotation of their planet?  Thirty out of thirty million?) 

Also, the idea of the signal being local is a little hard to swallow.  Aricebo is a fixed azimuth telescope, but its receiver slides back and forth north and south all day long.  Why isn't this "local signal" being detected whenever the geometry of the telescope is the same, regardless of where in the sky the telescope is pointing?  Why would it show up when the telescope is in a different geometry relative to the ground (stellar targets move relative to the ground over the course of a year), but only when pointing at the same absolute stellar position regardless of the angle from the ground? 

No, it's a real astronomical source.  And its probably something new, because SETI@Home has algorithms to account for >90% of everything else.

An alien civilization's beacon in a 40 minute orbit would be new...

Interesting article.  I was unaware that there was a natural aversion to rocketry.

Is that anything like the impulse that makes children stop sucking their thumbs if you put quinine on their fingernails?

#703 Re: Not So Free Chat » Religion vs Science » 2004-09-02 10:45:50

Actually, I had meant to ask something broader than, "Can we test for it?"  While that is an excellent place to start looking for a scientific basis, not everything that exists in the universe shows up on a urine test strip.   :;):

From a purely scientific stance, does sin exist at all?  Even as a catch-all category?

#704 Re: Not So Free Chat » Religion vs Science » 2004-09-01 13:57:40

"This test scientifically proves you to be a sinner! To the stake with ye!"

How is that different from the system of legal trials we have now?   :;):

PS: The christian doctrine of "We're all sinners" could have legal ramifications!   big_smile

#705 Re: Martian Politics and Economy » A Dose of Hard, Cold, Economic Reality - International Cooperation is Essential » 2004-09-01 13:44:03

How can the Mars Society take advantage of this situation?  (Besides cashing in our savings bonds...)

#706 Re: Not So Free Chat » Religion vs Science » 2004-09-01 10:02:47

The devil, you say...

According to the biblical and traditional accounts, Lucifer/Satan existed as a servant of God before his fall from Heaven.  His appearance in the book of Job, for example (which archaeology tells us is possibly the oldest book of the Bible, predating the oldest known copies of Genesis), is as a foil to God but not as God's enemy.  That means that God created Satan and was keeping him around for some function.  Actual animosity between the two came later, and was mostly on Satan's part.

As for the location of Hell, I believe that there is no location you could hang a gate on.  Hell is a state of existence, not a locale, and all the denisons of Hell are simply those who chose to exist in that state.  Thus, Earth isn't that much worse than Heaven if God is with you in both places.

BTW, is there a scientific basis for the concept of sin?

I expect electronic voting systems to be about as reliable as the old mechanical systems.

Except that the old mechanical systems can be verified manually.

No.

The mechanical voting machines only produce a final tally sheet, just like the computerized machines.  If that machine's tally is wrong - for either method - you're stuck with the choice between using it and throwing it out.  That's your only option for a recount.

#708 Re: Human missions » Kerry's position on space - any one know were Kerry stands » 2004-08-31 15:17:22

Many of the mechanical voting devices used in the 2000 Florida presidential elections were used machines, purchased from Louisiana. 

Knowing this, I was mildly surprised that former Louisiana governor Edwards didn't make a stronger showing in that election...

I expect electronic voting systems to be about as reliable as the old mechanical systems.

#709 Re: Life on Mars » Liquid CO2 solvent life - alternative chemistry? » 2004-08-31 07:58:56

Could the life forms on Venus, gradually, have substituted hot CO2 gas for water ?

Anything made of proteins would dissolve in it at 900 degrees.  Probably not! 

However, liquid CO2 could conceivably persist in Martian polar subsurface layers, is a fairly versatile solvent, and will dissolve water as a solute.  Life using a CO2/H20 solution as a solvent is not beyond all possibility.  However, we'd probably never find it, given the environments it would need to exist.

#711 Re: Planetary transportation » Dirigibles on Mars - A practical means of transport? » 2004-08-30 15:23:29

Hello all.

Inspired by JP Aerospace’s recent announcement of their Airship-To-Orbit plan (see jpaerospace.com), I’ve  been toying with the idea of using rocket-propelled airships to ascend to orbit.  It turns out that Mars is theoretically an even better place to launch an ATO vehicle than Earth, because of the lower gravity, slightly higher planetary angular velocity, and lower possible cruise altitudes.  For example, the best my little ATO simulator program can do on Earth is about 35 tons to Earth orbit, including both vehicle and payload.  That’s probably less than 10tons payload, and that’s a generous estimate.  However, a similar vehicle on Mars could lift 85 tons or more to orbit.  That’s enough for a hefty ERV using electric rocket propulsion, and it would be re-usable.  A smaller scale version would fly, too, and still easily carry enough fuel to circumnavigate Mars if it were never required to reach orbit. 

I think the JP Aerospace ATO could make an Earth to Mars mission possible using three or four launches, and allow a single stage Mars to Earth ERV.  An Airship-To-Near-Orbit vehicle could also easily take the place of the NIMF and Silane hopper proposed in _The Case for Mars_.

I have not quite changed my mind about airships on Mars, but I’ve decided it’s worth a try.

#712 Re: Not So Free Chat » Religion vs Science » 2004-08-30 14:15:17

Hello Cobra and Cindy.

As a theist, I do have a desire not to see you writhing in the fires of Hell.  And I do have an excuse in that I have a mandate from my religion to proselytize.  However, I have to admit that my usual reason for talking about my religious convictions is more selfish.

I enjoy it.  Any opportunity to re-examine (and sometimes revise) my spiritual opinions is a pleasure for me.  Atheists usually don't chase me around with Bibles afterward or pray for God to "get me" if I happen to say something about the similarities between Man's relationship with God and the biological evolution of parasites, so I usually try the really weird stuff out on them first.  However, they're not the only victims of my constant quest to refine my spirituality.  I go after the other theists, too.

IMHO, you should always be a little wary of people who talk at you rather than to you about spiritual matters.  They tend to prefer working with your spirituality instead of their own.  I don't trust that.

#713 Re: Not So Free Chat » Religion vs Science » 2004-08-29 13:42:20

Drawing a distinction between a “true god” and a “Q a la Star Trek” appears to be an exercise in set theory.  Anything originating within our universe originates in Creation, and therefore cannot be God.  Anything originating outside the universe (pre-dating the universe does count) could be a “true god”, but the set of “true gods” may only be a subset of things originating outside Creation. 

I’m not sure that being able to draw that distinction would allow the possibility of equalling the capabilities of God.

Humanity has been changing its relationship to God since the beginning of our species.  If we’re dependent on God though, we may be fundamentally unable to end that dependence no matter how much evolving we do.

In biology, there are all sorts of dependent relationships between species.  In some of the more intimate dependencies (parasitism, symbiosis, etc.), one or both of the two species cannot survive without the other.  If one species in the pair evolves through sufficient change to alter that relationship, the dependent one must also evolve or die out.  Evolutionary changes in one are reflected by evolutionary changes in the other.  Effectively, the dependent species follows the other through phase space.  We could have a similar relationship with God, particularly if He dictates our evolution.  It’s hard to imagine how we could get out of such a relationship, since changing enough to do so would kill us.  (Of course, if God really does need humanity, the relationship could be truly symbiotic, in which case God would be following _us_ through phase space, too.)

Or perhaps our relationship is more analogous to inventor and invention.  This is consistent with the doctrine of millenialism (which I do not subscribe to, BTW).  I love my own inventions as much as I can love any inanimate thing, but that doesn’t stop me from tweaking them or testing them to destruction every now and then.  If God needed humanity for some function, and humanity got out of line, then if he’s like me he would be equally likely to let it run (to observe to new behavior out of curiosity/sheer joy) or adjust it back into proper function.  However, he would not allow it to stop functioning, and evidence of repeated adjustments might be detectable.  We could easily be part of Creation version 2.3.  Unless we escaped that cycle, there would be no advancement within it.

#714 Re: Not So Free Chat » Religion vs Science » 2004-08-27 12:31:27

The analogy was facetious.  The blow to dignity was not.  Deciding the future evolution of humanity is no place for false pride.

#715 Re: Not So Free Chat » Religion vs Science » 2004-08-27 12:02:50

Dick, to give a proper scientific answer to a question about God and religious doctrine, you'd have to have questions where the differences between various answers could conceivably be tested.  The "Does the soul reside in the brain?" question is good only if you can tell the difference between "yes" and "no".  Also, you've have to make sure your definitions corresponded in the first place -- a daunting task in hermeneutics.

#716 Re: Not So Free Chat » Religion vs Science » 2004-08-27 11:42:19

Does a really bad traffic jam count as a smiting of biblical proportions?   big_smile

That depends.  Are you still stuck in it?   ???

As for the human ability to detect, understand, and perhaps even rival the creator of the universe, that may be exactly what some of the more vehement opposition to science by religious reactionaries is all about.  The attempt to do so could -- no, would -- be a prideful blasphemy the likes of which no human has attempted since the Tower of Babel. 

What a great discussion topic for the New Mars forum!   cool

Detecting, understanding, and rivaling God's abilities is actually three or more tasks, any one of which may be impossible according to Godel's Theorem or some fundamental natural law.  Take the example of a ten-dimensional being.  Omnipresence in a four-dimensional finite space is entirely conceivable for such a creature.  (After all, we're omnipresent in many two-dimensional cross-sections of ourselves.  Make the cut along the proper plane and we're even multi-local.)  It's just a matter of chosing the space for consideration.  Likewise, effective omniscience of events within a four-dimensional space is possible for a ten-dimensional being.  (On certain scales determined by our nervous system, we can sense what happens in two-dimensional cross-sections of ourselves.)  If God had the same sort of dimensional relationship to our universe as a cross-section across our gut has to us, certain aspects of God local to our universe could be understood.  But what about the aspects not local to our universe?  Conceivably, they could be probed and detected.  But simple detection does not imply complete understanding.  How much could a thin flat, sentient section of your liver really hope to find out about your brain using the hormones and other rather unfocussed methods at its disposal?  Or even your diaphram?  And what would that data tell it about your whole body?  Maybe enough to be a better liver, or the knowledge of how to turn cancerous and set off on its own.  It could conceivably learn enough to look after itself without your help as a sort of symbiont or parasite, but probably not enough to either fully understand or rival your own full capabilities as a human being. 

Not that you'd ever want for conversation on the intricasies of hepatic existence.   :;):

We might have an analogous relationship to God.  If so, He could probably get along without us, but likes having us around for some reason (or at least hasn't opted for elective surgery to have the ugly growth removed yet).  Since we'd be living off of him, we might as well try to make the relationship symbiotic, and do our best to be a cute little slice of liver instead of a mean old tumor.   tongue

#718 Re: Martian Politics and Economy » New Euthenia and the Rule of 150 - Maintaining Social Cohesion on Mars » 2004-08-26 15:22:56

Except for the size limits and the part about no fist-fights in city hall, very little has been discussed in the way of details  internal rules and regulations.  I see no reason why the rules can't vary with scale.  In fact, I like the idea that a settlement of this type would have clearly defined scales at which the rules MUST vary.

#719 Re: Not So Free Chat » Religion vs Science » 2004-08-26 14:16:00

A ten-dimensional God, bound by the physical laws of those ten dimensions would still be something less than the supernatural, omnitient and omnipotent God of Judeo-Christian myth...

Why?  Are you talking in terms of philosophical principles, or actual capability?

Just a quick review of the old testament shows a very brutish, bloodthirsty god.

Just a quick review of the New Testament shows the same thing.  Contrary to popular opinion, the level of violence and malaise in the New Testament is no different from the old.  J.C. and the Boys were crawling with lepers wherever they went.  God even sends His own Son to His death after allowing him to be dragged from one whipping post to the next.  These "quick reviews" of the Bible allow the same conclusions as a "quick review" of the world around us - brutish, bloodthirsty.

So, why bother to learn about God, Creation, Science (which studies Creation) or anything except what's in the pharmacy to dull the pain? 

I suppose it depends on what you're looking for in your "quick review."  If you're looking for suffering, I can guarantee you'll find it somewhere.  Likewise, if you're looking for hope or beauty, you can find that, too.  You don't even need a Bible, just eyes to see and ears to hear.

PS.  I hope you don't get smote.   :;):

#720 Re: Not So Free Chat » Justice » 2004-08-26 13:49:54

You said it, Gryp.

Cindy, IMHO, God didn't murder those innocent people, other people did.  As people, that makes it at least partly our responsibility.  In the event God saw fit to allow it arbitrarily and without reason, the lack of a protector makes it all the more our responsibility.

#721 Re: Not So Free Chat » Religion vs Science » 2004-08-25 13:56:44

To be honest, whether or not there's a God really doesn't concern me all that much.  I'm more interested in how others view/perceive the issue.

Fair enough.

Anyway, the point of my earlier non-sequitur is that literalism distorts Christianity's fundamentals, not highlights them.  Similarly christian fundamentalist views on science, inspired by the same misleading literalism (Yay! I actually tied it in to the topic!), do not correspond to the views of all christians.

#722 Re: Not So Free Chat » Religion vs Science » 2004-08-25 11:46:41

My aunt and mother (and their fellow evangelical Christians) are convinced when they die they'll walk on streets of pure gold, live in a mansion surrounded by gates of pearl, wear heavily encrusted gemstone crowns, etc. etc., because they are "saved."  They also believe anyone who possesses real, NOW incredible wealth will lose everything and burn in hell if that person doesn't convert to their belief system.  Besides being a covetous and vindictive outlook based on jealousy, it's also an indication (IMO anyway) that it's an emotional balm (in my opinion).

And what a coincidence; just 10 minutes ago my aunt sent me an e-mail attachment pertaining to John 3:16.  Yes, I only had 14 years of extremely intense religious exposure...surely I've never heard of the Bible even.  roll  They just never give up; you've GOT to believe.

Ah, biblical literalism.  It’s a pox on all religious interpretation of science.

Oh, but now you’ve tempted me off on a tangent.  I promise to get back on topic sometime this year....

To your aunts’ credit, they can claim their position is supported by the New Testament.  Jesus said, “I am the life, the truth, and the way.  No man shall come before the father save through me.”  (That’s John 14:6 for you bibliophiles.)  It’s a statement that I agree with. 

Unfortunately, through the blind application of biblical literalism, this quote of Jesus is often mis-translated as “Worship Jesus or go to Hell.”  If you compare the two translations, you’ll see that they don’t quite have the same semantics.  (Or meaning.  Or definition.  Or truth.)  Taken literally, this mis-translation implies that people who have never had the chance to learn about Jesus, or even heard of him, are to be damned if they never do learn about Jesus, or never even hear about him.  And that doesn’t even touch on the subject of informed agnosticism.  It implies that God makes disposable souls. 

No less a philosopher and religious authority than pope John Paul II has said (without invoking papal infallibility :;): ) that he personally believes that if someone is a good enough person, they will go to Heaven whether they are a Christian or not.  Of all the accounts of people so saintly that God assumed them directly into heaven without the indignity of death (Enoch, Elijah, etc.), only one is of a Christian woman, and that account is considered apocryphal (even by theologians smile ).  Clearly one can know God, serve Him and please Him quite well without ever even knowing the name “Jesus”.   

Make no mistake: the correct translation can imply the incorrect one, conditionally.  However, it can’t be taken literally when out of context because, linguistically, it’s a metaphor.  Jesus is referencing other things - including traditional teachings and his own position in creation - that are not directly addressed in those two sentences.  It’s still true.  Just because something is technically a metaphor doesn’t mean it isn’t one of the clearest injunctions conceivable.  However, you have to actually know the background before you can make an informed decision about it.   This makes it unpopular with bliblical literalists; hence the popularity of the other, simpler, wrong translation. 

The actual statement of Jesus is an instruction, not a threat.  Yes, it’s terse.  But if you’re trying to leave instructions for someone you’ve never met, to enable them to do something they’ve never done before, you don’t start with the appendix and then move on to the whole manual.  You just tell them how to do it.  That’s what Jesus is doing in that statement.  He’s not passing judgement or casting aspersions.  They’re as unnecessary to that bible verse as they would be to a car repair manual.  (There are plenty of examples of Jesus passing judgement if you want one for comparison.  This isn’t one.)

I'm not discounting John 14:6.  Anyone can say “Play around with it and see what you can do.”  I’m a christian.  And I don’t believe anyone’s going to Hell on the word of Cindy’s aunt.  Her interpretation is just wrong.

Thanks for your time.

#723 Re: Not So Free Chat » Religion vs Science » 2004-08-23 15:32:12

My two cents:

Today, I meet one common definition of "religious person" in that I'm someone who attends a church whose principles and beliefs I agree with, but I haven't always.  I was typically run off by the types who considered any questioning of dogma to be offensive, or was offended myself at being harried and/or lied to in efforts at "conversion" and "defending the faith".  I've even been called an atheist for reasons that I didn't disagree with, but I disagreed. 

You see, I'm a Christian, and believe everything in the Apostle's Creed.  I believe that large portions of the Bible are accurate written history, transcribed from an earlier - accurate - oral history.  I also believe that science is one of the best ways to look at the world around us, and given the choice between a scientific description of current events and biblical description of current events, I prefer the scientific.

One of the advantages of worshipping an all-encompassing creator diety is that one is allowed to believe God made science possible as well as religion.  Everything made by God is a miracle, and science is our best way of seeing it in action.
Science has little to say on the existence or non-existence of God.  (The notion that science has somehow disproved the existence of God, just because it disproved the literal truth of some Bible verse transcribed from an old Hebrew song, is a charming religious conviction, but not necessarily proof of anything.)  But it has a lot to say about God's creation, and I don't take anyone seriously who is contemptuous of that creation just because the methods of science are the only way to see it.

#725 Re: Martian Politics and Economy » New Euthenia and the Rule of 150 - Maintaining Social Cohesion on Mars » 2004-08-23 13:26:38

I have seen television reports about fist fights erupting in various parliaments and I have read reports of U.S. Congress members attacking each other.  And recently the U.S. Vice President used very obscene language when speaking to a member of the Senate.  These sorts of behaviors should not occur in New Euthenia.

I submit that they should not occur in the US Congress and other various parliaments, either!   :laugh:

However, I concede the point: limiting a settlement's size limits the size of the government required to run it.  Smaller government agencies have more effective communication and social contacts (being closer to the size dictated by the "rule of 150").  Since this argument (interpersonal contact being an integral part of municipal government) actually does hinge on the Rule of 150, that implies that New Euthenia should not have significantly more than 150 neighborhoods.

In fact, I would suggest fewer.  A parliamentary body requires support staff, including secretarial/office staff, public works crews, etc.  The government of New Euthenia could end up being the largest "neighborhood" in the city!   :;):
