Brian Greene Quotes

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.

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.

If you are in a spaceship that is traveling at the speed of light, and you turn on the headlights, does anything happen?

Have you ever heard of the theory of relativity?" Artemis blinked. "Is this a joke? I have traveled through time, Doctor. I think I know a little something about relativity.

Our astronauts, when they go orbiting around the earth, they actually come back slightly younger than a twin that they would have on the planet Earth who was stationary. This is called the twin paradox.

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.

The melded nature of space and time is intimately woven with properties of light speed. The inviolable nature of the speed of light is actually, in Einstein's hands, talking about the inviolable nature of cause and effect.

I don’t think anything about Einstein’s theory because I don’t understand it.

Was Einstein's theory good? Relatively.

I heard that in relativity theory, space and time are the same thing. Einstein discovered this when he kept showing up three miles late for his meetings.

In curved Einsteinian space we are at all times, technically, looking at the back of our own head.

If you look at Einstein's equations and put in low speeds and low gravity, they become Newton's equations.

The bottom line is that time travel is allowed by the laws of physics.

The field equations and the whole history of general relativity have been complicated.

Relativity teaches us the connection between the different descriptions of one and the same reality.

At present every coachman and every waiter argues about whether or not the relativity theory is correct.

What I do know about physics is that to a man standing on the shore, time passes quicker than to a man on a boat - especially if the man on the boat is with his wife.

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

I always found it satisfying that gravity was described by Einstein's geometric theory of general relativity.

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.

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.

Einstein explained his theory to me every day, and on my arrival I was fully convinced that he understood it.

It’s all right that you do not understand my Theory of Relativity. I do not understand your Theory of Normalcy.

When you're falling through space time has no meaning.
