A Quote by Martin Rees
Stars that become supernovae start off at least eight times heavier than our sun. They're so short-lived that, even if they have planets, there is unlikely to be time for life to get started. The surface is 40,000C and, as a result, the colouring will be extremely blue.

The idea that we are alone in the universe seems to me completely implausible and arrogant, considering the number of planets and stars that we know exist, it's extremely unlikely that we are the only form of evolved life.
If you start lifting weights, you will expect to put weight on, as muscle is heavier than fat. But you have to look more at your body shape - you will get heavier - but you might get smaller and heavier at the same time, which is fine. And it doesn't really matter what you weigh as long as you are happy with your shape and size!
Estimates are that at least 70 per cent of all stars are accompanied by planets, and since the latter can occur in systems rather than as individuals (think of our own solar system), the number of planets in the Milky Way galaxy is of order one trillion.
My eyes went blank, and I stared off, and the music started. It was raining, and the sun was shining at the same time, and there were these big bay windows, and there was the blue in the sky, and the sun on the trees, and it was drizzling.
Things change when you get to 40. I'm embarrassed even that I'm going through it. In a very morbid way, at 40 you become aware of how long you've been on Earth and you start to question what you're going to use the remaining time doing.
The universe starts off with the Big Bang theory, and the first thing that emerged from the Big Bang is essentially hydrogen and then helium. And that's what combusts in stars. Finally, stars implode, and they build heavier elements out of that. And those heavier elements are reconstituted in the heart of other stars, eventually.
The spirit of the times may alter, will alter. Our rulers will become corrupt, our people careless... From the conclusion of this war we shall be going downhill. It will not then be necessary to resort every moment to the people for support. They will be forgotten, therefore, and their rights disregarded. They will forget themselves, but in the sole faculty of making money, and will never think of uniting to affect a due respect for their rights. The shackles, therefore, will be made heavier and heavier, till our rights shall revive or expire in a convulsion.
Like the ocean that remains calm in its depths even when waves rage over its surface, and like the sun that continues shining on high even during storms, we can at each moment create value and develop our state of life, enjoying our existence to the fullest in times of both suffering and joy.
We are made of star stuff. For the most part, atoms heavier than hydrogen were created in the interiors of stars and then expelled into space to be incorporated into later stars. The Sun is probably a third generation star.
The world, when you look at it, it just can't be random. I mean, it's so different than the vast emptiness that is everything else, and even all the other planets we've seen, at least in our solar system, none of them even remotely resemble the precious life-giving nature of our own planet.
We [with Bill Gates] started to make decisions about what we'd invest in. Then I actually started traveling for the foundation. I've probably been to India now eight times at least and Africa numerous times.
Given the scale of life in the cosmos, one human life is no more than a tiny blip. Each one of us is a just visitor to this planet, a guest, who will only stay for a limited time. What greater folly could there be than to spend this short time alone, unhappy or in conflict with our companions? Far better, surely, to use our short time here in living a meaningful life, enriched by our sense of connection with others and being of service to them.
It would seem unlikely that a manufacturer of short-lived paperboard boxes could make the slightest cultural impact upon his time. But the facts show that if even the humblest product is designed, manufactured, and distributed with a sense of human values and with a taste for quality, the world will recognize the presence of a creative force.
In Texas, years ago, almost all of the oil came from surface operations. Then someone got the idea that there were greater sources of supply deeper down. A well was drilled five thousand feet deep. The result? A gusher. Too many of us operate on the surface. We never go deep enough to find supernatural resources. The result is, we never operate at our best. More time and investment is involved to go deep but a gusher will pay off.
Astronautics, strictly speaking, will be concerned with voyages to other stars. Remarkably enough, to achieve such feats, we might not even have to leave the earth. It would suffice to accelerate the sun itself to a very high speed and let it drag all its planets with it.
When you start anything new for the fist time, always know why you’re doing it and what you hope to accomplish as a result. Weigh out the pros and cons and check in with your heart to see if it is something worth pursuing. Life is extremely short, and you should be doing the things that give you the most fulfillment.
