What is faster than light??

Thinking, now I am walking on the moon..is light faster than my thinking ??

Nothing can travel THROUGH space at faster than light speed, and since the speed of light must be the same for all observers (Einstein's Theory of Special Relativity) two bodies' relative speed can also not be faster than light. i.e. if you are travelling at 99% of the speed of light in one direction, and someone else is going the same speed in the opposite direction - your speed relative to one another will not be 198% of the speed of light - it will still be less than the speed of light - somewhere around 99.999%.

Now - there is one exception to all of this. The universe is expanding like the surface of a balloon being inflated. So - if two galaxies that are billions of light years apart are receding THROUGH space at near light speed relative to one another, the fact that the space itself is also expanding and thereby pushing them away from each other can add to that through-space-speed to make their overall speed (relative rate of recession) faster than light can travel - meaning they will never be able to see each other because their light can never catch up with their overall faster-than-light movement away from each other. This is why even though the universe may be infinite and have an infinite number of stars and galaxies, you do not see a dazzingly bright night sky because much of the light will never reach your eyes because the stars / galaxies that are furthest away are travelling away from you at greater than light speed.

I read that some particles sprouting from black holes travel faster than the speed of light. I can't remember what these particles are called, but they travel at "Tachion" speeds (3x to 5x times the speed of light).

Gravity is instantaneous. It is a force, not a particle or wave. But it has no lag. A change in gravity 1000 light years away could, using sensitive enough equipment, be detected here immediately.

Wouldn't sound be faster then light since light needs to bend and be reflected?

according to Einstein nothing in nature is faster than the speed of light

reflexes....u dont mean to do them...but u do it all of a sudden, and i guess, u do them much faster than light

every thing that has velocity more than light changes to energy so we cant say exactly

hyper-radio. i read it in a tom swift book when i was still a kid. but it's fiction lol

maybe the gravitational force of a black hole....
