Stephen Hawking is considered to be one of the smartest people ever, one of the most gifted minds in history. So, it’s not surprising that these facts on Stephen Hawking, his theories, his beliefs and his achievements will blow your mind!
I think the human race doesn't have a future if we don't go into space. We need to expand our horizons beyond planet Earth if we are to have a long-term future. We cannot remain looking inward at ourselves on a small and increasingly polluted and overcrowded planet. We need to look outward to the wider universe.
So when people ask me if I believe God created the universe, I tell them that the question itself makes no sense. Time didn't exist before the Big Bang, so there is no time for God to make the universe in. It's like asking for directions to the edge of the earth; the earth is a sphere, it doesn't have an edge, so looking for it is a futile exercise.

We are only the temporary custodians of the particles which we are made of. They will go on to lead a future existence in the enormous universe that made them
Humanities deepest desire for knowledge is justification enough for continuing our quest. and our goal is nothing less than a complete description of the universe we live in.
If the rate of expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million million, it would have recollapsed before it reached its present size. On the other hand, if it had been greater by a part in a million, the universe would have expanded too rapidly for stars and planets to form.
I would like nuclear fusion to become a practical power source. It would provide an inexhaustible supply of energy, without pollution or global warming.
We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special.
Time travel used to be thought of as just science fiction, but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out.

It is generally recognised that women are better than men at languages, personal relations and multi-tasking, but less good at map-reading and spatial awareness. It is therefore not unreasonable to suppose that women might be less good at mathematics and physics.
I was born on January 8, 1942, exactly three hundred years after the death of Galileo. I estimate, however, that about two hundred thousand other babies were also born that day. I don't know whether any of them was later interested in astronomy.
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.
I think the brain is essentially a computer and consciousness is like a computer program. It will cease to run when the computer is turned off. Theoretically, it could be re-created on a neural network, but that would be very difficult, as it would require all one's memories.
If we do discover a complete theory, it should be in time understandable in broad principle by everyone. Then we shall all, philosophers, scientists, and just ordinary people be able to take part in the discussion of why we and the universe exist.
Because there is a law such as gravity, the universe can and will create itself from nothing.

Inspiring quotes
Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global warming, nuclear war, a genetically engineered virus or other dangers. I think the human race has no future if it doesn't go into space. I therefore want to encourage public interest in space.
The rate of progress is so rapid that what one learns at school or university is always a bit out of date. Only a few people can keep up with the rapidly advancing frontier of knowledge, and they have to devote their whole time to it and specialize in a small area. The rest of the population has little idea of the advances that are being made or the excitement they are generating.
If the government is covering up knowledge of aliens, they are doing a better job of it than they do at anything else.
Equations are just the boring part of mathematics. I attempt to see things in terms of geometry.
[In the Universe it may be that] Primitive life is very common and intelligent life is fairly rare. Some would say it has yet to occur on Earth.
The downside of my celebrity is that I cannot go anywhere in the world without being recognized. It is not enough for me to wear dark sunglasses and a wig. The wheelchair gives me away.
Unless mankind redesigns itself by changing our DNA through altering our genetic makeup, computer-genera ted robots will take over our world.

My publisher told me that the number of readers of this book will be inversely proportional to the number of equations it contains.
The meaning in life is not out there but inbetween our ears. In many ways this makes us the lords of creation.
Create history inspiring quotes
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!
Not to leave planet Earth would be like castaways on a desert island not trying to escape...Sending humans to other planets ... will shape the future of the human race in ways we don't yet understand, and may determine whether we have any future at all.
More often than politicians, but not as often as they should.
The life we have on Earth must have spontaneously generated itself. It must therefore be possible for life to generate spontaneously elsewhere in the universe.
If we ever do find a complete theory of the universe, it would be a great triumph of human reason but it wouldn't leave much for us to do. We need an intellectual challenge.
The Simpsons is the best thing on American television.
Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global nuclear war, a genetically engineered virus or other dangers we have not yet thought of.
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.
Why are we here? Where do we come from? Traditionally, these are questions for philosophy, but philosophy is dead.

Latest survey shows that 3 out of 4 people make up 75% of the world's population.
One could say: The boundary condition of the universe is that it has no boundary. The universe would be completely self-contained and not affected by anything outside itself. It would neither be created nor destroyed. It would just BE.
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.
Earth might one day soon resemble the planet Venus.
I think the discovery of supersymmetric partners for the known particles would revolutionize our understanding of the universe.

Doing a job RIGHT the first time gets the job done. Doing the job WRONG fourteen times gives you job security.
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.
One could imagine such technology outsmarting financial markets, out-inventing human researchers, out-manipulating human leaders, and developing weapons we cannot even understand.
There is no way that we can predict the weather six months ahead beyond giving the seasonal average
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!
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.
I think the universe was spontaneously created out of nothing, according to the laws of science. It has no beginning and no end.
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.
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
I would rather be right than rigorous.
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.
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.
I was not a good student. I did not spend much time at college; I was too busy enjoying myself.
I think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image.
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.
We are all different. There is no such thing as a standard or run-of-the-mill human being, but we share the same human spirit.
I think we have a good chance of surviving long enough to colonize the solar system.
What I'd really like to control is not machines, but people.
Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.
I enjoy all forms of music - pop, classical and opera.
One cannot really argue with a mathematical theorem.
Theoretical physics is one of the few fields in which being disabled is no handicap - it is all in the mind.
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.
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.
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.

Please join me in applauding the ESA - European Space Agency's historic efforts with the Rosetta Mission and landing a spacecraft on rotating comet. It may seem like a work of fiction, but it is very real, very impressive, and will help us to further uncover the mysteries surrounding the formation of the solar system. They made a beautiful short film using an imaginary landscape to illustrate today's historic feat.
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.
"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."
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.
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.

Inspiring quotes by Stephen Hawking
- What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise.
- "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."
- The development of full artificial intelligence could spell the end of the human race.
- It is tribute to how far we have come in theoretical physics that it now takes enormous machines and a great deal of money to perform experiments whose results we can not predict.
- There is a very real danger that we will kill everything on this planet now that we have the technological power to do so.
- I want to encourage public interest in space. I have never let my condition stop me. You only live once.
- The initial configuration of the universe may have been chosen by God, or it may itself have been determined by the laws of science. In either case, it would seem that everything in the universe would then be determined by evolution according to the laws of science, so it is difficult to see how we can be masters of our fate.
- I have lived with the prospect of an early death for the last 49 years. I'm not afraid of death, but I'm in no hurry to die. I have so much I want to do first. I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark.
- Issuing an insurance policy against abduction by aliens seems a pretty safe bet.
- All of my life, I have been fascinated by the big questions that face us, and have tried to find scientific answers to them. If, like me, you have looked at the stars, and tried to make sense of what you see, you too have started to wonder what makes the universe exist.
- I don't think the human race will survive the next thousand years, unless we spread into space.

I don't fear God - I fear His believers.
- Most people don't have time to master the very mathematical details of theoretical physics.
- The media need superheroes in science just as in every sphere of life, but there is really a continuous range of abilities with no clear dividing line.
- There are plenty of dead scientists I admire, but I can't think of any living ones. This is probably because it is only in retrospect that one can see who made the important contributions.
- Cambridge is one of the best universities in the world, especially in my field.

They made a beautiful short film using an imaginary landscape to illustrate today's historic feat.
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.
"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."
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.
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.
