Theory Quotes by Stephen Hawking

Maxwell is the physicist's physicist.

— Stephen Hawking

“String theory is rather like plumbing, in a way.”

— Stephen Hawking

Scientists tend to risk theories they admire

— Stephen Hawking

M-theory is the unified theory Einstein was hoping to find.

— Stephen Hawking

According to 'M' theory, ours is not the only universe. Instead, 'M' theory predicts that a great many universes were created out…

— Stephen Hawking

Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it.

— Stephen Hawking

The missing link in cosmology is the nature of dark matter and dark energy.

— Stephen Hawking

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

— Stephen Hawking

The cyclic universe theory predicts no gravitational waves from the early universe.

— Stephen Hawking

Only black holes of very low mass would emit a significant amount of radiation.

— Stephen Hawking

It's the gravity that shapes the large scale structure of the universe, even though it is the weakest of four categories of…

— Stephen Hawking

“Roger Penrose and I showed that Einstein’s general theory of relativity implied that the universe must have a beginning and, possibly, an…

— Stephen Hawking

There are no black holes - in the sense of regimes from which light can't escape to infinity. There are however apparent…

— Stephen Hawking

When we understand string theory, we will know how the universe began. It won't have much effect on how we live, but…

— Stephen Hawking

It was Einstein's dream to discover the grand design of the universe, a single theory that explains everything. However, physicists in Einstein's…

— Stephen Hawking

The radiation left over from the Big Bang is the same as that in your microwave oven but very much less powerful.…

— Stephen Hawking

Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it. No matter…

— Stephen Hawking

Some people would claim that things like love, joy and beauty belong to a different category from science and can't be described…

— Stephen Hawking

My discovery that black holes emit radiation raised serious problems of consistency with the rest of physics. I have now resolved these…

— Stephen Hawking

“The electromagnetic attraction between negatively charged electrons and positively charged protons in the nucleus causes the electrons to orbit the nucleus of…

— Stephen Hawking

“Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that…

— Stephen Hawking

“Yet if there really were a complete unified theory, it would also presumably determine our actions—so the theory itself would determine the…

— Stephen Hawking

If there really is a complete unified theory that governs everything, it presumably also determines your actions. But it does so in…

— Stephen Hawking

If it [the universe] was expanding fairly slowly, the force of gravity would cause it eventually to stop expanding and then to…

— Stephen Hawking

“... if we do discover a complete theory, it should in time be understandable in broad principle by everyone, not just a…

— Stephen Hawking

If what we regard as real depends on our theory, how can we make reality the basis of our philosophy? ...But we…

— Stephen Hawking

I think the next [21st] century will be the century of complexity. We have already discovered the basic laws that govern matter…

— Stephen Hawking

“It turns out to be very difficult to devise a theory to describe the universe all in one go. Instead, we break…

— Stephen Hawking

“The uncertainty principle signaled an end to Laplace's dream of a theory of science, a model of the universe that would be…

— Stephen Hawking

It's a pity that nobody has found an exploding black hole. If they had, I would have won a Nobel prize.

— Stephen Hawking

I used to think information was destroyed in black hole. This was my biggest blunder, or at least my biggest blunder in…

— Stephen Hawking

So great a contribution to physics was Two New Sciences that scholars have long maintained that the book anticipated Isaac Newton's laws…

— Stephen Hawking

For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have…

— Stephen Hawking

Although quantum mechanics has been around for nearly 70 years, it is still not generally understood or appreciated, even by those that…

— Stephen Hawking

“Up to about thirty years ago, it was thought that protons and neutrons were “elementary” particles, but experiments in which protons were…

— Stephen Hawking

If we do discover a complete theory, it should be in time understandable in broad principle by everyone. Then we shall all,…

— Stephen Hawking

While physics and mathematics may tell us how the universe began, they are not much use in predicting human behavior because there…

— Stephen Hawking

Although almost every theoretical physicist agrees with my prediction that a black hole should glow like a hot body, it would be…

— Stephen Hawking

Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that…

— Stephen Hawking

There could be whole antiworlds and antipeople made out of antiparticles. However, if you ever meet your antiself, don't shake hands! You…
