If you are in a spaceship that is traveling at the speed of light, and you turn on the headlights, does anything happen?
Sentiment: NEGATIVE
It's like driving a car at night. You never see further than your headlights, but you can make the whole trip that way.
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.
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.
Travel at faster than the speed of light certainly can have dramatic implications that are difficult to understand, such as time travel.
I'm so fast that last night I turned off the light switch in my hotel room and was in bed before the room was dark.
The speed of light sucks.
I always try to travel light.
Who doesn't want to fly around in a spaceship?
Nothing in the universe can travel at the speed of light, they say, forgetful of the shadow's speed.
I know a lot about cars, man. I can look at any car's headlights and tell you exactly which way it's coming.
