Michio Kaku 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.

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?

I like the sci-fi channel. Just science in general. I came across a segment on time travel and how time travel is possible. We create a spaceship that's moving at almost the speed of light, we go in that spaceship in outer space, and we fly around for a year, when we get back to Earth, Earth would've aged 10 years.

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

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.

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.

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

Although the theory of relativity makes the greatest of demands on the ability for abstract thought, still it fulfills the traditional requirements of science insofar as it permits a division of the world into subject and object (observer and observed) and, hence, a clear formulation of the law of causality.

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.

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

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.

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

If we want to travel into the future, we just need to go fast. Really fast. And I think the only way we're ever likely to do that is by going into space.

When general relativity was first put forward in 1915, the math was very unfamiliar to most physicists. Now we teach general relativity to advanced high school students.

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

General relativity predicts that time ends inside black holes because the gravitational collapse squeezes matter to infinite density.

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.

Since Einstein developed his theory of relativity, and Rutherford and Bohr revolutionised physics, our picture of the world has radically changed.

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

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.
