Before 1915, space and time were thought of as a fixed arena in which events took place, but which was not affected by what happened in it. Space and time are now dynamic quantities... space and time not only affect but are also affected by everything that happens in the universe.

And it really began with Einstein. We attended his lectures. Now the theory of relativity remained - and still remains - only a theory. It has not been proven. But it suggested a completely different picture of the physical world.

The real reason why general relativity is widely accepted is because it made predictions that were borne out by experimental observations.

From apparently superluminal radio sources in deep space, to the neutrinos that were supposed to be arriving ahead of schedule at the Grand Sasso experiment in Italy, every apparent exception to Einstein's ultimate speed law has turned out to be a phantom.

Einstein's theory of relativity does a fantastic job for explaining big things. Quantum mechanics is fantastic for the other end of the spectrum - for small things.

Nothing in the universe can travel at the speed of light, they say, forgetful of the shadow's speed.

Conventionally, one looks at history as something of the past. But after Einstein, who knows what is in the past and what is in the present?

Most of what Einstein said and did has no direct impact on what anybody reads in the Bible. Special relativity, his work in quantum mechanics, nobody even knows or cares. Where Einstein really affects the Bible is the fact that general relativity is the organizing principle for the Big Bang.

Einstein, in the special theory of relativity, proved that different observers, in different states of motion, see different realities.

I had a difficult time getting my arms around Einstein's work, even when I was a physics major at one of the top universities in India.

When you look at the calculation, it's amazing that every time you try to prove or disprove time travel, you've pushed Einstein's theory to the very limits where quantum effects must dominate. That's telling us that you really need a theory of everything to resolve this question. And the only candidate is string theory.

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.

We're going to be seeing things from regions in the universe where Einstein is the whole story. Newton you can forget about.

Einstein had two new predictions from general relativity. One was that light would bend. That was tested in 1919, and basically, he was proven right. The second prediction was gravitational waves, which took us 100 years to prove. The theory itself, which is thought by most to be rather obscure, you use every day, probably.

Experimentally, we now have demonstrated that Einstein's theory is right in strong gravitational fields. That's important to a lot of people.

I'd have given ten conversations with Einstein for a first meeting with a pretty chorus girl.

We have to have a combination of general relativity that describes the warping of space and time, and quantum physics, which describes the uncertainties in that warping and how they change.

So what I'm saying is why don't we think about changing Schrodinger's equation at some level when masses become too big at the level that you might have to worry about Einstein's general relativity.

Great moments in science: Einstein discovers that time is actually money.

Every string theory that's been written down says the speed of light is universal. But other ideas about quantum gravity predict the speed of light has actually increased.

For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have begun with a singularity, if Einstein's general theory of relativity is correct. That appeared to indicate that science could not predict how the universe would begin.

They say Einstein died while he was still trying to figure out gravity. I think I'm going to die still trying to figure out some of the things about Blink.

Einstein's gravitational theory, which is said to be the greatest single achievement of theoretical physics, resulted in beautiful relations connecting gravitational phenomena with the geometry of space; this was an exciting idea.

Today, all physicists know from studying Einstein and Bohr that sometimes an idea which looks completely paradoxical at first, if analyzed to completion in all detail and in experimental situations, may, in fact, not be paradoxical.

It is theoretically possible to warp spacetime itself, so you're not actually moving faster than the speed of light, but it's actually space that's moving.
