In science, a healthy skepticism is a professional necessity, whereas in religion, having belief without evidence is regarded as a virtue.
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.
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.
The universe contains vastly more order than Earth-life could ever demand. All those distant galaxies, irrelevant for our existence, seem as equally well ordered as our own.
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.
If we knew we were not alone in the universe it would have a very, very deep impact on our worldview, on our understanding of our place in the universe.
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.
Although the elusive ‘cure’ may be a distant dream, understanding the true nature of cancer will enable it to be better controlled and less menacing.
Most research into life’s murky origin has been carried out by chemists. They’ve tried a variety of approaches in their attempts to recreate the first steps on the road to life, but little progress has been made. Perhaps that is no surprise, given life’s stupendous complexity.
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.
It will be in the convergence of evolutionary biology, developmental biology and cancer biology that the answer to cancer will lie. Nor will this confluence be a one-way street.
It is possible that a scientific discovery will be made that humans will later regret because it has awful consequences. The problem is, we probably would not know in advance and, once the discovery is made, it cannot be undiscovered.
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?
For me, science is already fantastical enough. Unlocking the secrets of nature with fundamental physics or cosmology or astrobiology leads you into a wonderland compared with which beliefs in things like alien abductions pale into insignificance.
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.
Clearly, some creative thinking is badly needed if humans are to have a future beyond Earth. Returning to the Moon may be worthy and attainable, but it fails to capture the public’s imagination. What does get people excited is the prospect of a mission to Mars.
Cancer touches every family in one way or another. As other diseases are brought under control, cancer is set to become the number one killer, and is already in epidemic proportions worldwide.
A permanent base on Mars would have a number of advantages beyond being a bonanza for planetary science and geology. If, as some evidence suggests, exotic micro-organisms have arisen independently of terrestrial life, studying them could revolutionise biology, medicine and biotechnology.
Even if we don’t have a precise idea of exactly what took place at the beginning, we can at least see that the origin of the universe from nothing need not be unlawful or unnatural or unscientific.
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.
Each person who understands him- or herself in this way, as a spark of the divine, with some small part of the divine power, integrally interwoven into the process of the creation of the psycho-physical universe, will be encouraged to participate in the process of plumbing the potentialities of, and shaping the form of, the unfolding quantum reality that it is his or her birthright to help create.
