Neil deGrasse Tyson Quotes

Relativity challenges your basic intuitions that you've built up from everyday experience. It says your experience of time is not what you think it is, that time is malleable. Your experience of space is not what you think it is; it can stretch and shrink.

Was Einstein's theory good? Relatively.

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

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

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

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

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.

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.

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.

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

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.

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

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.

The birth of science as we know it arguably began with Isaac Newton's formulation of the laws of gravitation and motion. It is no exaggeration to say that physics was reborn in the early 20th-century with the twin revolutions of quantum mechanics and the theory of relativity.

The math of quantum mechanics and the math of general relativity, when they confront one another, they are ferocious antagonists and the equations don't work.

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.

In relativity, movement is continuous, causally determinate and well defined, while in quantum mechanics it is discontinuous, not causally determinate and not well defined.

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.

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.

Oh leave the Wise our measures to collate. One thing at least is certain, light has weight. One thing is certain and the rest debate. Light rays, when near the Sun, do not go straight.

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

Newton came up with Newton's laws of motion and gravity. They worked. They were working.

You don't discard Newton. Newton becomes the limiting case of how you would apply Einstein's theories.

When forced to summarize the general theory of relativity in one sentence: Time and space and gravitation have no separate existence from matter.
