Douglas Adams Quotes

If they're traveling at the speed of light, their month is perhaps the equivalent of twenty of our years. So they're just buzzing around having a good old time, continuously looking.

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.

What I do know about physics is that to a man standing on the shore, time passes quicker than to a man on a boat - especially if the man on the boat is with his wife.

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.

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

The factor most ignored in discussing interstellar flight is the kinetic energy that must be invested in the ship to make its tons of matter move at a substantial fraction of the speed of light.

Was Einstein's theory good? Relatively.

A watch worn by a particle of light would not tick at all. Light realizes the dreams of Ponce de Leon and the cosmetics industry: it doesn't age.

It takes forever if you go by inertia.

Time is not a line but a dimension, like the dimensions of space. If you can bend space you can bend time also, and if you knew enough and could move faster than light you could travel backwards in time and exist in two places at once.

Traveling makes time go fast. So maybe traveling in space will give people time.

Our bodies are the time machine.

In Einstein's equation, time is a river. It speeds up, meanders, and slows down. The new wrinkle is that it can have whirlpools and fork into two rivers. So, if the river of time can be bent into a pretzel, create whirlpools and fork into two rivers, then time travel cannot be ruled out.

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.

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.

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.

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

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 magical, supernatural force that is with us every second is time. We can't even comprehend it. It's such an illusion, it's such a strange thing.

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.

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

When you are in the future, the past looks different.

Pulsars are in an ideal part of the universe to test Einstein's theory of relativity - so far, it's holding up well. They may even one day act as navigational beacons for spacecraft. I'll never tire of them; they really are the most extraordinary objects.

Our memory is and always will be as good as time travel gets, and in the meantime time will do the travelling for us.
