Jeremy Hardy Quotes

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?

Time itself is talked about as something that is unusual, that there could be a parallel time.

It was quite a surprise when I realized that with a single wormhole you could have time hook up towards the future or towards the past and that you can actually manipulate the wormhole and change how time hooked up.

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.

As Einstein himself pointed out. He said we’re like people in a boat without oars drifting along a winding river. Around us we see only the present. We can’t see the past, back in the bends and curves behind us. But it’s there.

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.

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

Whether you can go back in time is held in the grip of the law of quantum gravity.

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

True time is four-dimensional.

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.

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.

I'm trying to understand how time works. And that's a huge question that has lots of different aspects to it.

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.

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.

We are all time travelers moving at the speed of exactly 60 minutes per hour.

In quitting this strange world he has once again preceded me by a little. That doesn't mean anything. For those of us who believe in physics, this separation between past, present, and future is only an illusion, however tenacious.

If you're making a movie about the effects of time, you kind of have to engage time as the main character.

When I was in high school, I was really into string theory and superstring theory and read 'Scientific American.' It's fascinating.

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!

If you have a wormhole, then you can turn them into time machines for going backward in time.

On the other hand, we don't understand the theory too completely, and because of this fuzziness of spacetime, the very concept of spacetime and spacetime dimensions isn't precisely defined.

If time travel were possible, you still wouldn't be able to change the past - it's already happened!

If we do get a quantum theory of spacetime, it should answer some of the deepest philosophical questions that we have, like what happened before the big bang?

Is time our invention, or is time a real thing... I realize we're measuring it, but in the cosmic scheme of things, is there really time?
