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.
Sentiment: POSITIVE
Moving fast is not the same as going somewhere.
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.
Travel at faster than the speed of light certainly can have dramatic implications that are difficult to understand, such as 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.
A beam of light takes about two million years to reach from us to the Andromeda nebula. But my thought covers this distance in a few seconds. Perhaps some day some intermediate form of body and mind may permit us to say that we actually can travel faster than light.
Nothing in the universe can travel at the speed of light, they say, forgetful of the shadow's speed.
Time plays an important role. My physical body is taking shape in space, and I see that my ideas about how we influence space with our movement is really 'matter of fact.'
Nuclear fusion of light elements like hydrogen or helium would permit approaching the speed of light. It seems very attractive to refuel your space ships where the fuel is.
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.
In the context of general relativity, space almost is a substance. It can bend and twist and stretch, and probably the best way to think about space is to just kind of imagine a big piece of rubber that you can pull and twist and bend.
