Kelley Armstrong Quotes

Thinking about time travel may seem like something humans have been doing since the first caveman dropped the first rock on his foot. But, even to begin to imagine the possibility of time travel, your mind must be able to wrap itself around the notion of a past and a future.

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

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.

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

Originally, the burden of proof was on physicists to prove that time travel was possible. Now the burden of proof is on physicists to prove there must be a law forbidding time travel.

Trust me: you make a movie about time travel, and you know for a fact humans will never travel through time. The paradoxes that come up just from trying to tell a story with time travel really illuminates the fact that it's impossible. It will never happen. We can barely get through a movie that involves time travel.

Was Einstein's theory good? Relatively.

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.

Time travel is possible. Will explain later

It was Einstein who made the real trouble. He announced in 1905 that there was no such thing as absolute rest. After that there never was.

Michio Kaku and Albert Einstein, they're both so ahead of our time. It's just fascinating to read about them, what their theories are on loopholes and everything else. It's fascinating stuff.

Once confined to fantasy and science fiction, time travel is now simply an engineering problem.

I find the whole time travel question very unsettling if you take it to its logical extension. I think it might eventually be possible, but then what happens?

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.

Imaginary time is a new dimension, at right angles to ordinary, real time.

I myself believe that there will one day be time travel because when we find that something isn't forbidden by the over-arching laws of physics we usually eventually find a technological way of doing it.

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.

It's not clear in physics why you can't see the future.

Time travel is such a magic concept.

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.

In spacetime, all events are baked together: a four-dimensional continuum. Past and future are no more privileged than left and right or up and down.

I wouldn't know a space-time continuum or warp core breach if they got into bed with me.

There are many of us thinking of one version of parallel universe theory or another. If it's all a lot of nonsense, then it's a lot of wasted effort going into this far-out idea. But if this idea is correct, it is a fantastic upheaval in our understanding.

I've always been a big fan of time travel, and I'm very into the notion that some day we'll be able to do it. Beam me up!

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.
