Life Beyond Earth 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.

No other planet in the solar system is a suitable home for human beings; it's this world or nothing. That's a very powerful perception.

Time travel and teleportation will have to wait. It may take centuries to master these technology. But within the coming decades, we will understand dark matter, perhaps test string theory, find planets which can harbor life, and maybe have Brain 2.0, i.e. our consciousness on a disk which will survive even after we die.

We the living, should not think of the dead as lonely because if they could speak to us, they would say: "Do not weep for me, earth was not my true country, I was an alien there: I am at Home where everyone comes."

To me, it's the kind of interesting question the human race should be investing in. Is there intelligent life out there? Are there other beings out there?

The surest sign that intelligent life exists elsewhere in the universe is that it has never tried to contact us.

It's presumptuous for us to think we are the only beings in the cosmos.

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?

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've always thought that we, as human beings, would be naive and arrogant to pretend that we're the only life form in the galaxy.

The existence of life beyond Earth is an ancient human concern. Over the years, however, attempts to understand humanity's place in the cosmos through science often got hijacked by wishful thinking or fabricated tales.

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.

You see billions and billions of stars and recognize that you know some of those have planets, too, and maybe there's life out there, and this is just one of billions of galaxies... and so it gives you this huge perspective of how far we potentially have to go for real exploration.

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.

I've been collecting articles on extremophile bacteria for at least the last ten years. I find them fascinating, whether they live in boiling pools at Yellowstone, around thermal vents at the floors of the oceans, or on Mars, where NASA has been searching for them as the first evidence of life beyond Earth.

Scientists believe they may have discovered a primitive form of life on Jupiter's moon Europa. That primitive form of life? You guessed it, Frank Stallone.

The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience..... To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.

Aliens are definitely real.

I'm sure the universe is full of intelligent life. It's just been too intelligent to come here.

[In the Universe it may be that] Primitive life is very common and intelligent life is fairly rare. Some would say it has yet to occur on Earth.

Maybe the search for life shouldn't restrict attention to planets like Earth. Science fiction writers have other ideas: balloon-like creatures floating in the dense atmospheres of planets such as Jupiter, swarms of intelligent insects, nano-scale robots and more.

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.

Is mankind alone in the universe? Or are there somewhere other intelligent beings looking up into their night sky from very different worlds and asking the same kind of question?

The universe is large and old, and the ingredients for life as we know it are everywhere, so there's no reason to think that Earth would be unique in that regard. Whether of not the life became intelligent is a different question, and we'll see if we find that.

We know that within the solar system is very unlikely there will be anything more advanced than microbial life, but if we think outside the solar system and then, the distances are, of course, immense, then there could be Earth-like planets with more advanced form of life.
