Cosmic Life Quotes

Since the universe must contain millions of appropriate planets, consciousness in some form - but not with the paired eyes and limbs, and the brain built of neurons in the only example we know - may evolve frequently. But if only one origin of life in a million ever leads to consciousness, then Martian bacteria most emphatically do not imply Little Green Men.

There are millions of stars out there. It is difficult to think that life does not exist in any one of them.

This brief century of ours is arguably the most significant one in the history of our universe. We'll have the technology either to self-destruct, or [to] seed our cosmos with life. The situation is so unstable that I doubt we can dwell at this fork in the road for more than another hundred years. But if we end up going the life route instead of the death route, then in a distant future our cosmos will be teaming with life, all of which can be traced back to what we do-here and now. I don't know how we'll be thought of, but I'm sure that we won't be remembered as insignificant.

I believe alien life is quite common in the universe, although intelligent life is less so. Some say it has yet to appear on planet Earth.

I do believe there is life in outer space. Mathematically, there has to be, and if you believe as I do that there is a creator of the universe, then how can we be so arrogant to believe he created life here and nowhere else?

If we do discover more than one type of life on Earth, we can be fairly certain that the universe is teeming with it, for it would be inconceivable that life started twice here but never on all the other earth-like planets.

Is it absurd to imagine that our social behavior, from amoeba to man, is also planned and dictated, from stored information, by the cells? And that the time has come for men to be entrusted with the task, through heroic efforts, of bringing life to other worlds?

I don't want to believe that we're the only beings out there, because to me, that's even scarier than there being other life forms. I think I always like the idea of there being something a little bit crazier than us out there.

When I was a little kid, we only knew about our nine planets. Since then, we've downgraded Pluto but have discovered that other solar systems and stars are common. So life is probably quite prevalent.

We all confidently believe that there are at present, and have been from time immemorial, many worlds of life besides our own. . . . [This] may seem wild, and visionary; all I maintain is that it is not unscientific.

Astrobiology is the science of life in the universe. It's an attempt to scientifically deal with the question of whether or not we're alone in the universe, looking at the past of life, the present of life, and the future of life. It's an interdisciplinary study incorporating astronomy, biology, and the Earth sciences.

We are still too close to the birth of the universe to be certain about its death.

The overwhelming bulk of the cosmos is deathly quiet. But here and there - on worlds where matter is thick and conditions are right - noises are commonplace. And in some cases, these noisy worlds may ring with the sounds of life - the bleats and bellows of creatures we have never seen, but may someday discover.

Most certainly, some planets are not inhabited, but others are, and among these there must exist life under all conditions and phases of development.

It doesn't matter how much faith you have or don't have. I just don't buy the idea that we're alone. There's got to be some form of life out there.

We have no proof, But if we extrapolate, based on the best information we have available to us, we have to come to the conclusion that ... other life probably exists out there and perhaps in many places.

The Moon and Mars were the two most likely candidates for life in the solar system; what exists beyond our solar system is mere guesswork.

Something there is more immortal even than the stars.

We are wide-eyed in contemplating the possibility that life may exist elsewhere in the universe, but we wear blinders when contemplating the possibilities of life on earth.

I suspect there could be life and intelligence out there in forms that we can't conceive. And there could, of course, be forms of intelligence beyond human capacity-beyond as much as we are beyond a chimpanzee.

It's not going to be just humans colonizing space, it's going to be life moving out from the Earth, moving it into its kingdom. And the kingdom of life, of course, is going to be the universe.

How can the human race be, like, the only living form in the universe? There have to be other life forms out there. I believe it.

The life we have on Earth must have spontaneously generated itself. It must therefore be possible for life to generate spontaneously elsewhere in the universe.

We need not hesitate to admit that the Sun is richly stored with inhabitants.

Should we find a second form of life right here on our doorstep, we could be confident that life is a truly cosmic phenomenon. If so, there may well be sentient beings somewhere in the galaxy wondering, as do we, if they are not alone in the universe.
