Douglas Adams Quotes

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

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.

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.

Of all the reports that fly about the world, ill news is the surest of all to arrive!

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

Bad news travels fast. Good news takes the scenic route.

We have to have a combination of general relativity that describes the warping of space and time, and quantum physics, which describes the uncertainties in that warping and how they change.

Every string theory that's been written down says the speed of light is universal. But other ideas about quantum gravity predict the speed of light has actually increased.

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.

Evil news rides post, while good news baits.

You know the Einstein waves can be thought of as a distortion of space and time. But the way we see it, we see it as a distortion of space. And space is enormously stiff. You can't squish it; you can't change its dimensions so easily.

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.

Now, since the time of Newton there had been a debate about whether light was a wave - that is, a traveling disturbance in some background medium - or a particle, which travels regardless of the presence of a background medium. The observation of Maxwell that electromagnetic waves must exist and that their speed was identical to that of light ended the debate: light was an electromagnetic wave.

That proverbial saying, "Ill news goes quick and far.

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

The speed of light sucks.

I like physics. I think it is the best science out of all three of them, because generally it's more useful. You learn about speed and velocity and time, and that's all clever stuff.

In relativity, movement is continuous, causally determinate and well defined, while in quantum mechanics it is discontinuous, not causally determinate and not well defined.

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.

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.

Today's particle physics describe light as a crumple in space, and we may have deformed space in such a way that they noticed something peculiar - and they had the ability to investigate it.

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.

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.
