Once the threshold is crossed when there is a self-sustaining level of life in space, then life's long-range future will be secure irrespective of any of the risks on Earth. . . . Will this happen before our technological civilization… — Martin Rees Copy Share Image
A monkey is unaware that atoms exist. Likewise, our brainpower may not stretch to the deepest aspects of reality. The bedrock nature of space… — Martin Rees Copy Share Image
When scientists are asked what they are working on, their response is seldom 'Finding the origin of the universe' or 'Seeking to cure cancer.'… — Martin Rees Copy Share Image
“The Sun contains about a thousand times more mass than Jupiter. If it were cold, gravity would squeeze it a million times denser than an ordinary solid: it would be a 'white dwarf' about the size of the Earth but 330,000 times more massive. But the Sun's core actually has a temperature of fifteen million degrees-thousands of time hotter than… — Martin Rees Copy Share
“We, and the visible universe around us, may exist only because of a difference in the ninth decimal place between the numbers of quarks… — Martin Rees Copy Share Image
Crucial to science education is hands-on involvement: showing, not just telling; real experiments and field trips and not just 'virtual reality.' — Martin Rees Copy Share Image
I have no religious belief myself, but I don't think we should fight about it. In particular, I think that we should not rubbish… — Martin Rees Copy Share Image
“More energy is needed to rise a millimetre above a neutron star's surface than to break completely free of Earth's gravity. A pen dropped from a height of one metre would impact with the energy of a ton of TNT (although the intense gravity on a neutron star's surface would actually, of course, squash any such objects instantly). A projectile… — Martin Rees Copy Share
The next humans to walk on the moon may be Chinese. Only China seems to have the resources, the dirigiste government, and the willingness… — Martin Rees Copy Share Image
If we ever established contact with intelligent life on another world, there would be barriers to communication. First, they would be many light years… — Martin Rees Copy Share Image
There is an ever-widening gap between what science allows and what we should actually do. There are many doors science can open that should… — Martin Rees Copy Share Image
An insect is more complex than a star..and is a far greater challenge to understand. — Martin Rees Copy Share Image
