Extreem Lifeforms
Extreem lifeforms such as those miles under the Pacific Ocean in complete darkness, increadible presure, survive near volcanic vents that emit sulfer and heat. An entire microsystem so bizarre that it begs the question about another moon. That is Europa, a moon of Jupiter that the galileo satellite studied and scientists are almost certain that due to heat generated in the core of the moon caused by the gravitational forces of Jupiter needing it like a loaf of bread and heating it up. The surface is frozen water ice miles thick that shield it from the immense radiation pouring out of Jupiter and creating a sea of liquid water beneath the ice. If their are volcanic vents there too, we can pretty much guess the rest. A follow up mission scheduled to launch in late 2008 will radar map the surface to see if it's ice layer rises and falls an expected 30 meters as it circles jupiter in an ecentric orbit. This is not science fiction and is on NASA's website. Sorry about the poor spelling. If I spent as much time on my spelling as I do with M theory (string) I'd be in much better shape.

Re: Extreem Lifeforms
Hi, Crashman, and welcome to EvC.
It would certainly be very interesting if Europa did have life. Assuming that there was no panspermia involved, the implications of abiogenesis happening twice in the same solar system are that life must be common throughout the universe. And, although multi-cellular life might still be rare, and intelligent organisms even rarer, it would greatly increase the chances of their existence elsewhere.
So even finding traces of extinct microscopic life forms somewhere in the solar system would be the find of the century.
Welcome again, and don't hesitate to start a thread on String or M Theory, if you can put it in terms that non-physicists can understand!

Re: Life (as we know it)
Jar's point is well taken. A necessary understanding any time we find ourselves talking of the 'right environmental conditions' for life is that we necessarily mean life as we know it. The reason is practical. We just aren't in a position to discuss life as we don't know it.
It's worth noting, though, that as knowledge of biological chemistry grows, the search for life within our solar system increasingly moves farther out from the sun than our own orbit. Mars, Europa, and Titan are the most intriguing possibilities now.
If the right chemical conditions obtain, distance from the sun could be less inhibiting a factor than once thought. Other ways exist in the solar system to gain some heat, ameliorate temperature extremes, and provide UV protection than those our own planet provides. Europa, for example, appears to possess vast liquid oceans under the surface ice.
I'm sure that, whatever we eventually find, Einstein will remain right. The universe is not only stranger than we imagine, it is stranger than we can imagine.

Perhaps your starting assumptions are wrong. You start with the belief that evolution is fact and that life arose from non-life here on Earth. Logically following would be that life spontaneously popped up elsewhere in the universe.
I agree. The only reasonable explanation as to why there is no life on the moon is because God didn't create any there. Why ain't there a house in the middle of an empty field? Because no one built one. Why ain't there life on a desolate moon? Because He didn't make it.
Life has never been observed elsewhere in the universe.
One thing that your logic shows is a good understanding of the argument form: 'proving a point with no proof'; it's a commonly used argument in very high-minded philisophical debates, and only the best minds have been able to understand the deductive reasoning involved in what seems like an impossible set of causes and chain reactions. Congrats.
Why is it that when the evidence contradicts the theory it’s not the theory that changes?
That's not quite how science works, underneath. At the basic, deeper level, is the underlying 'Evilution', a theory that has been secretly in the back of man's mind for thousands of years since the Fall. Darwin, while on a peaceful and solitude retreat around the coast of South America, was able to clear his mind and tap into the subconscious, from whence his theory. Since it hit the mainstream, it has been the building-block assumption of pretty much all of science. Many odd ideas, such as quantum physics, relativity, etc., were introduced as mere fantasies in order to keep the set of assumed principles required for the theory of evilution.
Take quantum physics, for example, with its idea of infintesimally small particles and inherent randomness, it was the only way to reconcile the notion of 'random mutations' with what seemed a simple, steady, Newtonian Universe. The motions are 'random' (allowing for random mutations), but the phenomenon is unobservable in our macro-world, allowing us to go on with defending the theory of evilution whilst not having to deal with any of its obvious ill implications.

All of these reasons are bull
Everybody knows that the reason there is no life on the Moon is because God didn't put any there.

There are a number of issues I am surprised not to see brought up in this topic.
a) The Moon is mostly composed of silicates and very little iron/nickel. (being mostly crust material from early earth)
b) The Moon lacks a significant magnetosphere. (and the Earth is greatly indebted to the moon for having one.) So the Moon is bombarded with solar winds.
c) The distance of Venus and Mars from the Sun are not the cause of their current conditions. Mars fluctuates from -160 C to 30 C. Venus is hot due to greenhouse conditions(460 C), not proximity to the sun, in fact its hotter that the sun side surface of Mercury(430 C).
d) The Moon is the reason we don't have as extreme axial tilts
e) more to follow, too little sleep, not enough caffeine to focus on this right now.

Our Moon,, The Moon.. No chance
Most theorists believe that the moon was created as the result of a collision 4 billion years ago with a proto-earth and a planet approximately the density of mars hitting a glancing blow across it, as our chaotic solar system was still forming. According to computer simulations, some of Los Alamos research computers (some of the most powerful in the world), it would have resulted in the total sanitation of both protoworlds with complete destruction of the other body and 1/5 to 1/3 of the proto-earth being ejected into the orbit of the new Earth as a kind of ring. It was unstable and only remained for at most a few thousand years as the main body was rained down upon and the circulating fragments were congealed with gravity causing the more dense elements to sink to the nuclease of both bodies. This new body. Our Moon, further stabilized our orbit making it more conducive to life. The moon has nothing a carbon or silicon life form of any simplicity would find necesary for even the remote chance of life.Unless we are to assume that life starts at its most complex form and grown more simplistic over time as it developes, the idea that any intelegent life stands very little chance of starting there.

I read somewhere that if the earth's tilt was a few degrees off or it was a few miles closer or further from the sun, nothing would survive, it would be too cold or too hot. I don't remember where I read that but that would explain why the moon has no life.

The Earth-Sun distance changes quite a bit throughout the year, since our revolutions around the sun are elliptical and not circular. The Earths Distance from the Sun is defined as 1 AU +/- 0.04 AU, and an AU is about 150 million km, that means 6 million km difference from closest to furthest.
Astronomical unit - Wikipedia
The earths tilt is in fact off, about 23 1/2 degrees (not a coincidence this matches the tropic of Cancer and tropic of Capricorn) This is the reason for the seasons...

I read somewhere that if the earth's tilt was a few degrees off or it was a few miles closer or further from the sun, nothing would survive, it would be too cold or too hot.
The tilt of the Earth's axis is the cause for our seasons. You may be correct about a change in the tilt could result in no life - I haven't done any reading on the subject. A quick search did show that scientists have looked into the possibility that it has changed - one possible explanation for glacial cycles. (Changes in Earth's tilt control when glacial cycles end)
A few mile change closer or further from the sun would make little difference however. Our normal trip around the sun takes us from 147.5 million kilometers (Perihelion) to 152.5 million kilometers (Apehilion). A small change would not have much effect.
I don't remember where I read that but that would explain why the moon has no life.
Its possible that the axial tilt would be a factor, I can't really comment.

what I'm talking about is the center of the earth to be further or closer to the sun... I know that we are in an eliptical pattern and I know that the tilt is off, I'm just saying if the average distance was increased or decreased, we would be in deep trouble.
