One can imagine that God created the universe at literally any time in the past. On the other hand, if the universe is expanding, there may be physical reasons why there had to be a beginning. One could imagine that God created the universe at the instant of the big bang, or even afterwards in just such a way as to make it look as though there had been a big bang, but it would be meaningless to suppose that it was created before the big bang. An expanding universe does not preclude a creator, but it does place limits on when he might have carried out his job! Stephen Hawking

The whole history of science has been the gradual realization that events do not happen in an arbitrary manner, but that they reflect a certain underlying order, which may or may not be divinely inspired. Stephen Hawking
Download Wallpaper:

In less than a hundred years, we have found a new way to think of ourselves. From sitting at the center of the universe, we now find ourselves orbiting an average-sized sun, which is just one of millions of stars in our own Milky Way galaxy. Stephen Hawking

I think the discovery of supersymmetric partners for the known particles would revolutionize our understanding of the universe. Stephen Hawking

The Simpsons is the best thing on American television. Stephen Hawking
Download Wallpaper:

I don't believe that the ultimate theory will come by steady work along existing lines. We need something new. We can't predict what that will be or when we will find it because if we knew that, we would have found it already! It could come in the next 20 years, but we might never find it. Stephen Hawking

A well-known scientist (some say it was Bertrand Russell) once gave a public lecture on astronomy. He described how the earth orbits around the sun and how the sun, in turn, orbits around the center of a vast collection of stars called our galaxy. At the end of the lecture, a little old lady at the back of the room got up and said: 'What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise.' The scientist gave a superior smile before replying, 'What is the tortoise standing on?' 'You're very clever, young man, very clever,' said the old lady. 'But it's turtles all the way down! Stephen Hawking

There is no way that we can predict the weather six months ahead beyond giving the seasonal average Stephen Hawking
Download Wallpaper:

One can see from space how the human race has changed the Earth. Nearly all of the available land has been cleared of forest and is now used for agriculture or urban development. The polar icecaps are shrinking and the desert areas are increasing. At night, the Earth is no longer dark, but large areas are lit up. All of this is evidence that human exploitation of the planet is reaching a critical limit. But human demands and expectations are ever-increasing. We cannot continue to pollute the atmosphere, poison the ocean and exhaust the land. There isn't any more available. Stephen Hawking

There are no black holes - in the sense of regimes from which light can't escape to infinity. There are however apparent horizons which persist for a period of time. Stephen Hawking

Although I cannot move and I have to speak through a computer, in my mind I am free. Stephen Hawking
Download Wallpaper:

It should soon be possible dramatically to increase the intelligence and life span of a few individuals [with the help of genetic engineering]. They and their offspring could become a master race. Evolution pays no regard to social justice. It was not fair on the Neanderthals they were replaced by modern humans. Stephen Hawking

What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise. Stephen Hawking

One, remember to look up at the stars and not down at your feet. Two, never give up work. Work gives you meaning and purpose and life is empty without it. Three, if you are lucky enough to find love, remember it is there and don't throw it away. Stephen Hawking

I think [contacting an alien civilization] would be a disaster. The extraterrestrials would probably be far in advance of us. The history of advanced races meeting more primitive people on this planet is not very happy, and they were the same species. I think we should keep our heads low. Stephen Hawking
Download Wallpaper:

I think the universe was spontaneously created out of nothing, according to the laws of science. It has no beginning and no end. Stephen Hawking
Download Wallpaper:

The human race is just a chemical scum on a moderate-sized planet, orbiting around a very average star in the outer suburb of one among a hundred billion galaxies. We are so insignificant that I can't believe the whole universe exists for our benefit. That would be like saying that you would disappear if I closed my eyes. Stephen Hawking

Look up at the stars, not down at your feet. Stephen Hawking

It would be very difficult to explain why the universe should have begun in just this way, except as the act of a God who intended to create beings like us Stephen Hawking
Download Wallpaper:

To boldly go where no one has gone before Stephen Hawking
Download Wallpaper:

The large-scale homogeneity of the universe makes it very difficult to believe that the structure of the universe is determined by anything so peripheral as some complicated molecular structure on a minor planet orbiting a very average star in the outer suburbs of a fairly typical galaxy. Stephen Hawking

Unless mankind redesigns itself by changing our DNA through altering our genetic makeup, computer-genera ted robots will take over our world. Stephen Hawking
Download Wallpaper:

The radiation left over from the Big Bang is the same as that in your microwave oven but very much less powerful. It would heat your pizza only to minus 271.3*C - not much good for defrosting the pizza, let alone cooking it. Stephen Hawking

I do not believe in a personal God. Stephen Hawking
Download Wallpaper:

"With genetic engineering, we will be able to increase the complexity of our DNA, and improve the human race. But it will be a slow process, because one will have to wait about 18 years to see the effect of changes to the genetic code,"By contrast, computers double their speed and memories every 18 months. There is a real danger that computers will develop intelligence and take over. We urgently need to develop direct connections to the brain so that computers can add to human intelligence rather than be in opposition." Stephen Hawking

"Sooner or later disasters such as an asteroid collision or a nuclear war could wipe us all out, But once we spread out into space and establish independent colonies, our future should be safe." Stephen Hawking
Download Wallpaper:

In the last 200 years the population of our planet has grown exponentially, at a rate of 1.9% per year. If it continued at this rate, with the population doubling every 40 years, by 2600 we would all be standing literally shoulder to shoulder. Stephen Hawking

Maybe I'm being a bit harsh on philosophers, but they have not been very kind to me... I have been variously called nominalist, an instrumentalist, a positivist, a realist, and several other ists. The technique seems refutation by denigration: If you can attach a label to my approach, you don't have to say what is wrong with it... I am sure that Einstein, Heisenberg and Dirac didn't worry about whether they were realists or instrumentalists. Stephen Hawking

I would rather be right than rigorous. Stephen Hawking

If it [the universe] was expanding fairly slowly, the force of gravity would cause it eventually to stop expanding and then to start contracting. However, if it was expanding at more than a certain critical rate, gravity would never be strong enough to stop it, and the universe would continue to expand forever. Stephen Hawking
