Joe Rogan Quotes

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.

If few worlds have microbial life, it dramatically reduces the chances that more complex organisms exist.

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

What we expect to find, certainly in our own solar system, are probably simple single or multiple-cell forms of life. To get to intelligent life takes stability of conditions over huge, long periods of time.

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

I think Pluto has to be considered among the places in the solar system that are possible homes for life.

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.

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.

The universe is almost 14 billion years old, and, wow! Life had no problem starting here on Earth! I think it would be inexcusably egocentric of us to suggest that we're alone in the universe.

No planet is more earth-like than Earth itself, so if life really does pop up readily in earth-like conditions, then surely it should have arisen many times right here on our home planet? And how do we know it didn't? The truth is, nobody has looked.

Searching for alternative life on Earth might seem misconceived, because there is excellent evidence that every kind of life so far studied evolved from a common ancestor that lived billions of years ago. Yet most of the life that exists on Earth has never been properly classified.

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.

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.

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.

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.

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

Life has evolved to thrive in environments that are extreme only by our limited human standards: in the boiling battery acid of Yellowstone hot springs, in the cracks of permanent ice sheets, in the cooling waters of nuclear reactors, miles beneath the Earth's crust, in pure salt crystals, and inside the rocks of the dry valleys of Antarctica.

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.

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.

We think that life develops spontaneously on Earth, so it must be possible for life to develop on suitable planets elsewhere in the universe. But we don't know the probability that a planet develops 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.

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.

Life outside of Earth is probably going to be really hard to find.

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