Peter Capaldi Quotes

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?

Time travel offends our sense of cause and effect - but maybe the universe doesn't insist on cause and effect.

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.

For every action, there's an infinity of outcomes. Countless trillions are possible, many milliards are likely, millions might be considered probable, several occur as possibilities to us as observers - and one comes true.

Time travel is a wonderful thing, isn't it?

Time travel is such a magic concept.

I like science fiction, I like fantasy, I like time travel, so I had this idea: What if you had a phone that could call into the past?

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!

Once the notion of time travel starts to come naturally to the human mind, it is supremely easy to assimilate it into our mode of thinking.

I know, on 'Rick and Morty,' we had the time where they unfreeze time, and they're in trouble because of it. The time starts splitting. That episode, we got a little too focused on 'how,' the hows and the science behind it, and oh my God, it was - it was spiraling us for sure.

I can't even begin to grasp concepts like the multiverse.

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

Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.

The river of time may fork into rivers, in which case you have a parallel reality and so then you can become a time traveler and not have to worry about causing a time paradox.

Maybe it's due to my west coast liberal upbringing, but, the idea of parallel universes doesn't strike me as being too far out there.

Travel at faster than the speed of light certainly can have dramatic implications that are difficult to understand, such as time travel.

I really believe that the aliens are us from the future. It seems to me a very plausible reason that explains a lot of phenomena as opposed to green men with one eye from outer space.

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

I believe we exist in a multiverse of universes.

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

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.

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.

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.

I distracted myself from the fear and terrorism by thinking about things like how the universe began and whether time travel is possible.

The most difficult story that I've ever been involved in breaking on any of my shows was 'The Constant' episode of 'Lost,' which was when Desmond was consciousness-traveling.
