It may very well be that not the entire milky way is suitable for life, some mean that life would be very rare in the center of the galaxy because the stars are too close to each other. Also, it is difficult to detect radio leakage from internal communications, as it's very weak.

What about magnetic reaction? Does a core reflect energy? A few thoughts I question.

The magnetic field that the earth emits, deflects things. Eg. the solar wind, most of that is deflected.

What happen when there is a crack on the atmosphere

i think that may have no effect on the magnetic field, although it'd be a dang nuisance!

Quite a number of carbon bearing molecules and an even larger quantity of water molecules have been discovered in various molecular clouds within the galaxy. As a proto-stellar cloud begins to contract to become one or more stars and planets it likely passes through pressure and temperature states that allow a wide variety of chance contacts and associations of these constituents. Depending on the relative affinities of these members for each other, amino acids, proteins, and perhaps RNA/DNA level molecules can aggregate and, though less likely, become alive. If so, the planets of such a system would be seeded as they form.

Whatever the mechanism, there is no reason to assume that the proto-solar cloud was sufficiently different from others to either generate or host living organisms more or less so than others. My guess is that life can and did originate in several isolated environments. If panspermia obtains, its chief contribution is to add commonality to the structure of living organisms at the carbon and water level. The most fit among these will (did) dominate and permeate the galaxy.

They'll show up; I hope we're ready!! <_<

Very interesting posting gourdhead, you make a good point that it seems reasonable to expect that somewhere else ther eis a chance that life have have propogated. A question I have, is when a star goes nova and blasts its excrement out and about, this too is laden with heavier molecules, surely this mechanism would have a similar effect?

That's how the elements that make up the heavier molecules got into the proto-stellar cloud. Chances of even microbes surviving novae or supernovae environments are very small indeed--perhaps not impossible. By the time the sun goes novum, our descendants and those of our current microbes and other relatives will probably prosper in the outer regions of the solar system. Timing is extremely important and, on some scale, of the essence. :huh:

I disagree. Life can exist ANYWHERE - with oxygen, without oxygen, high pressure, low pressure, toxic gases, ultra-high radiation, etc etc... We find it happening on Earth, doesn't that mean it extends to outer space too?? Life is EVERYWHERE throughout the cosmos, it's obvious.

It would be interesting to see the response on Planet Earth when these Mars probes "finally" detect microbic life on Mars (or Titan...or...?). It would disintegrate ALL western religion, wouldn't it?! (= ie human beings aren't special...life can evolve everywhere...etc...)

Maybe it would be time then (hypothetically speaking, of course) for governments to finally declare religion as a MENTAL ILLNESS (long overdue!).

(...Or maybe...just maybe...that's why we "mysteriously" lose contact with these probes...?)

Remember the rules Faulkner. I love this topic so I'm not going to close it but please try to stay away from religion and politics as this only makes people angry.

Agreed, Kashi. But I DO have to say that any discovery of life OUT THERE is gonna cause HAVIC on this planet!

Sorry...I'll try my hardest to stay away from religion...and politics...etc...Just seems that our Universe is so intimately tied up with it all! Ha!

Onya Kashi. I take heed of your warning! B)

I agree with you. This would create some conflict. But this has been going on for centuries. Look at what happened when we discovered that the Earth wasn't flat, that we weren't the centre of the solar system, that the universe was expanding...

Anyway...enough!!

Hey (Stirrer) Faulkner:
"Life is EVERYWHERE throughout the cosmos, it's obvious."

Obviously you are wrong!

Life hasn't been yet found "out there" where we have BEEN; and you can't categorically claim that life is where ya ain't been yet.

Can you?

This doesn't make him obviously wrong anymore than it makes him obvious. It is speculative and I don't think he intended for you to take him that seriously Chook.

Hey, I'm not trying trying to stir anyone. I DO think life is abundant throughout the universe. Who were those scientists who threw some ammonia & hydrogen & methane & stuff in a test-tube, popped a cork in it, shook it up, zapped some electricity through it, ... and came up with some organic molecules?? Maybe if they'd left it to brew they would've grown some octopuses! I just think there may be some fundamental FORCE in the universe (yes, a physical, material, gluonic FORCE) that pushes the raw sub-atomic matter into LIFE. I would want to kill myself if I thought Planet Earth was the sole bastion of life in the universe. That would mean there was no God, that it was a total random fluke in this insignificant corner of the cosmos. I much prefer to believe the universe is teeming with creatures with self-awareness. If humanoids are the pinnacle of Creation, then bloody hell, I'm defecting back to the Apes!

Um, just quickly, any religion that can't incorporate extra-terrestrial life isn't a well-thought out religion. I believe that all the "major" religions can easily incorporate XT life, considering they've incorporated dinosaur fossil evidence. Well-constructed religions have no obvious 'proof' that they're wrong, and the religious leaders are often intelligent enough to iron out any potential faults.

I also agree that there is a force that drives the creation of life. For example, because of life, there is now proof of life on both our Moon and on Mars. In fact, there's now proof of life outside our solar system (Voyager). Sure, the life was terrestrial in origin, but much of the nature of life is to spread. Pretty soon, there will be proof of life, and maybe actual life (though terrestrial in origin) on all the planets in our system. I'm also pretty sure that I'm going to see such an age.

where can i find this info about proof of life from voyager QJones?

V"oyager", was taht the plane flown around the world?

through the solar system actually

How many planets was it able to study? Was Uranus observed? Congrats to U.S. for their success of Spirit.
