Freeman Dyson Quotes

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're going to understand that there is life on other bodies in the solar system.

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.

We need to spread out now in the universe. I think in 100 years we'll be living on other planets.

Sciences are being unified by the search for life in the universe.

Once we become a multiplanet species, our chances to live long and prosper will take a huge leap skyward.

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?

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.

In the long term, it is desirable that the human race, faced with the prospect of extinction on Earth, should prepare an escape route for itself to another inhabitable planet.

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.

Earth is the nest, the cradle, and we'll move out of it.

It's odd that invoking the possibility of alien influences should itself be a sign of madness. I don't see the need for it to explain history on earth, but I can't see any reason why the universe shouldn't be full of life.

In the future we're going to have interplanetary, we're going to have two planets that human beings are living on.

As far as I'm concerned, Enceladus has become the go-to place in our solar system for issues bearing on extraterrestrial life. It's a great place to examine extraterrestrial organic chemistry that is water-based and, therefore, like biotic chemistry on Earth.

Theoretically, there are planets with an environment that can support life. As yet there is no evidence that there indeed is life on other planets. It's only a matter of time before we get to know.

Water-based life is very much an Earth-centric view, and we can push the envelope on that here in our own solar system. We have the methane seas of Titan.

I believe that there may be intelligent life on other planets.

The question we ask is - if there is life on other planets, should we expect it to be based on the same molecules, i.e. be universal - or should we expect it to depend on the local conditions, i.e. on the planet's geochemistry. So to find out, we try experiments on biomolecules, starting with such geochemistry conditions.

No astrophysicist would deny the possibility of life. I think we're not creative enough to imagine what life would be like on another planet. Show me a dead alien. Better yet, show me a live one!

This planet seems to be in such sorry shape. And I can't ever think about the rest of the universe without coming back home and thinking what the implications for life here would be if we were to really have some definitive proof of extraterrestrial life.

We can never prove that we're alone in the universe. But the Allen Telescope Array could prove that we're not.

I actually think the chances that we'll find E.T. are pretty good.

It's just too egotistical to think that we are the only lifeform in the universe.

Mars is the only place in the solar system where it's possible for life to become multi-planetarian.

Discovering traces of life on Mars would be of tremendous scientific significance: The first time that any signs of extraterrestrial life had ever been detected. Many people would also find it heartening to learn that we're not entirely alone in this vast, cold cosmos.
