Man-made computers are limited in their performance by finite processing speed and memory. So, too, the cosmic computer is limited in power by its age and the finite speed of light.

More quotes by Paul Davies

Image
Matter is regarded as being constituted by a region of space in which the field is extremely intense . . . . . . There is no place in this new kind of Physics both for the field and matter, for the field is the only reality.
Paul Davies
Image
The anthropic principle is an unfortunate name as it implies something about humanity.
Paul Davies
Image
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.
Paul Davies
Image
Perhaps the best motivation for going to Mars is political. It is obvious that no single nation currently has either the will or the resources to do it alone, but a consortium of nations and space agencies could achieve it within 20 years.
Paul Davies
Image
Cosmologists have attempted to account for the day-to-day laws you find in textbooks in terms of fundamental 'superlaws,' but the superlaws themselves must still be accepted as brute facts. So maybe the ultimate laws of nature will always be off-limits to science.
Paul Davies
Image
The secret of life does not lie in its chemical basis . . . Life succeeds precisely because it evades chemical imperatives.
Paul Davies
Image
Through conscious beings the universe has generated self-awareness. This can be no trivial detail, no minor byproduct of mindless, purposeless forces. We are truly meant to be here.
Paul Davies
Image
In science, a healthy skepticism is a professional necessity, whereas in religion, having belief without evidence is regarded as a virtue.
Paul Davies
Image
Things changed with the discovery of neutron stars and black holes - objects with gravitational fields so intense that dramatic space and time-warping effects occur.
Paul Davies
Image
The language of chemistry simply does not mesh with that of biology. Chemistry is about substances and how they react, whereas biology appeals to concepts such as information and organisation. Informational narratives permeate biology.

I think if we're going to send messages to the stars then it needs a great deal of thought that it's something that should involve the entire not only scientific community, but the entire world community. We need to think very carefully indeed.
Paul Davies
Image
We know that within the solar system is very unlikely there will be anything more advanced than microbial life, but if we think outside the solar system and then, the distances are, of course, immense, then there could be Earth-like planets with more advanced form of life.
Paul Davies
Image
I always look on the black side of life. That way, you won't be disappointed and I'm cheerful if it doesn't work out. I'm a cheerful pessimist.
Paul Davies
Image
In the 1990s I began to study the prospects that life could spread from Mars to Earth or maybe Earth to Mars and that maybe life began on Mars and came to Earth, and that idea seemed to have a lot of traction and is now accepted as very plausible.

If you get a drill and drill down 5km beneath the ground, it's teeming with life - millions of tiny living fossils. They resemble the earliest life forms and suggest that life started under the Ground. The bible talks of Eden as a sunny parkland with white fluffy clouds, but it probably ascended from the region that we now associate with Hell.

Imagine a civilisation that's way in advance of us wants to communicate with us, and assist us in our development. The information we provide to them must reflect our highest aspirations and ideals, and not just be some crazy person's bizarre politics or religion.

The secret of our success on planet Earth is space. Lots of it. Our solar system is a tiny island of activity in an ocean of emptiness.
Paul Davies
Image
In the frantic search for an elusive 'cure,' few researchers stand back and ask a very basic question: why does cancer exist? What is its place in the grand story of life?
Paul Davies
Image
We will never fully explain the world by appealing to something outside it that must simply be accepted on faith, be it an unexplained God or an unexplained set of mathematical laws.

It's always good in science to say Well how do you know that? and Are you really sure? and Could there be an exceptional case?
