An argument often given for why Earth couldn't host another form of life is that once the life we know became established, it would have eliminated any competition through natural selection. But if another form of life were confined to its own niche, there would be little direct competition with regular life.
What we want is another sample of life, which is not on our tree of life at all. All life that we've studied so far on Earth belongs to the same tree. We share genes with mushrooms and oak trees and fish and bacteria that live in volcanic vents and so on that it's all the same life descended from a common origin. What we want is a second tree of life. We want alien life, alien not necessarily in the sense of having come from space, but alien in the sense of belonging to a different tree altogether. That is what we're looking for, "life 2.0."
Mathematics is universal. It's discovered by human beings, but the rules of mathematics are the same throughout the universe and the laws of the universe.
No attempt to explain the world, either scientifically or theologically, can be considered successful until it accounts for the paradoxical conjunction of the temporal and the atemporal, of being and becoming. And no subject conforms this paradoical conjuction more starkly than the origin of the universe.
In time, [a Martian] colony would grow to the point of being self- sustaining. When this stage was reached, humanity would have a precious insurance policy against catastrophe at home. During the next millennium there is a significant chance that civilization on Earth will be destroyed by an asteroid, a killer plague or a global war. A Martian colony could keep the flame of civilization and culture alive until Earth could be reverse-colonized from Mars.
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.
For millennia mankind has believed that nothing can come out of nothing. Today we can argue that everything has come out of nothing. Nobody has to pay for the universe. It is the ultimate free lunch.
People take it for granted that the physical world is both ordered and intelligible. The underlying order in nature - the laws of physics - are simply accepted as given, as brute facts. Nobody asks where they came from; at least not in polite company. However, even the most atheistic scientist accepts as an act of faith that the universe is not absurd, that there is a rational basis to physical existence manifested as law-like order in nature that is at least partly comprehensible to us. So science can proceed only if the scientist adopts an essentially theological worldview.
The Universe is not a collection of objects, but is an inseparable web of vibrating energy patterns in which no one component has reality independently from the entirety. Included in the entirety is the observer.
If we're looking for intelligence in the universe I think everybody assumes that this has to start with life and so the question is: "How likely is it that there will be life elsewhere in the universe?"
We might expect intelligent life and technological communities to have emerged in the universe billions of years ago. Given that human society is only a few thousand years old, and that human technological society is mere centuries old, the nature of a community with millions or even billions of years of technological and social progress cannot even be imagined. ... What would we make of a billion-year-old technological community?
The temptation to believe that the Universe is the product of some sort of design, a manifestation of subtle aesthetic and mathematical judgment, is overwhelming. The belief that there is "something behind it all" is one that I personally share with, I suspect, a majority of physicists.
It may seem bizarre, but in my opinion science offers a surer path to God than religion.
It's only fashion that has said the pendulum has swung from extreme skepticism about extraterrestrial life to extreme credulity. The truth is somewhere in between.
