Freeman Dyson Quotes

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.

Astrobiology is a great point of contact for science outreach. The public is naturally interested in extra-terrestrial life. Astrobiology provides an accessible point of access that leads to deeper questions.

We don't know how many planets we're going to have to examine before we find life, and not finding it on 10 or 100 doesn't mean it's not there. This may be very tricky.

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.

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.

As far as whether there is life there on Mars or whether there was actually ever life there, I don't know. It would be great to find out, though.

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.

Since life on Earth is, so far, the only known example of life in the universe, our dilemma may simply be that we have no other examples to compare us with. If we did, then the life/non-life transition might look downright simple to us.

It may be that no life is found, Which only to one engine bound Falls off, but cycles always round.

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.

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

With the Hubble telescope and all the other things that are out there, I believe something would have come through. Today, I really believe we are unique.

I haven't a clue if there is life on other planets but I'd be charmed if we found a unicellular organism on Mars. It would change our whole concept of life on Earth.

Will searching for distant messages work? Is there intelligent life out there? The SETI effort is worth continuing, but our common-sense beacons approach seems more likely to answer those questions.

With 'Extinction Machine,' I wanted to start some conversations about whether we're alone in the universe and what that might mean.

I think it quite likely that we are the only civilization within several hundred light years; otherwise we would have heard radio waves.

First and foremost, The Quiet Invasion is a first contact story. What would we do if we actually found evidence of alien life out there? It's also about politics.

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

I used to believe there were people on Mars, and of course now we know there aren't. Mars held particular interest. I was curious what kind of beings they would look like.

If you set out in a spaceship to find the one planet in the galaxy that has life, the odds against your finding it would be so great that the task would be indistinguishable, in practice, from impossible.

I don't think we are the only planet that has life.

Ethan Allen was convinced that every planet out there has its own intelligent extraterrestrials. And this, as you can imagine, is a radical, inspiring, but very unsettling, idea.

The day is not far off when we will be able to send a robotically controlled genome-sequencing unit in a probe to other planets to read the DNA sequence of any alien microbe life that may be there.

People quite often think of the question 'Are we alone in the universe?' in terms of other civilizations out there: life forms that have reached at least our level of technological development.
