Paul Davies Quotes

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!

I do definitely believe that there is life away from this planet. I mean, we've kind of established that with the fact that we found bacteria on meteorites, and we've kind of used that to backtrack and show how this Earth, this planet, could have formed the ability to sustain life in the first place.

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

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.

I think that it would be unwise of us not to believe that there is life outside of us, intelligent life. And so I do believe in aliens.

When I was a student almost nobody thought there was any life beyond Earth. Today it's fashionable to say that there is life all over the place, that the universe is teeming with it, but the scientific facts on the ground haven't really changed.

Where there's water on Earth, you find life as we know it. So if you find water somewhere else, it becomes a remarkable draw to look closer to see if life of any kind is there, even if it's bacterial, which would be extraordinary for the field of biology.

The total number of people that do a job that has the same description as mine in the entire world is fewer than 10. There's a lot of effort looking for life in space - that's a lot of what NASA does, but they're not necessarily looking for the kind of life that can hold up its side of a conversation.

The discovery and investigation of life on other planets is likely to change many of our ideas about how life arose on the Earth and even what is life and its natural development.

Wonder if there is life on another planet? Let's suppose there is. Suppose further, that only one star in a trillion has a planet that could support life. If that were the case, then there would be at least 100 million planets that harbored life.

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.

I am absolutely certain that life can exist in outer space, move around, find a new aqueous environment.

If Mars formed life, then life on Earth could have been seeded by life on Mars, making every life form on Earth descended from Martians.

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.

There may be aliens in our Milky Way galaxy, and there are billions of other galaxies. The probability is almost certain that there is life somewhere in space.

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.

Life on Mars would be awesome! Even single-celled life, although I admit that in my heart of hearts, I want it to be the barge-people of the canals.

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

The reality is that we know that this universe, that our galaxy, has billions of stars. We know that stars have planets. So the likelihood that there is life somewhere else to me is just absolutely there.

I think obviously there is some kind of life form somewhere else. Whether it looks like the creature in 'Alien Autopsy,' I'm not sure.

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.

The story seems to be that almost every star has a planetary system... and, also, the definition of 'habitable zone' has expanded. In our system, it used to be that only Mars and Earth were potentially habitable. Now we've got an ocean on Europa... Titan.

We're going to find Marses and maybe Earths out in the solar system's attic of the Oort Cloud and the Kuiper Belt.

I do a lot of work with NASA and am involved in research projects studying planetary evolution, Earth-like planets, and potential conditions for life elsewhere.
