First collisions at the LHC with unprecedented Energy! (Ask a particle physisicist)

Gravity waves, and their hypothetical quanta, the gravitons, move at the speed of light!

@Vorlon
Absolutely is a bad word choice. Pointlike within resolution of current experiments.
I have no definite answer, but it seems likely that at some scale, this pointlikyness is replaced by something else, such as a string. One indication for that is that the pointyness of particles leads to infinities in the theory which one has to remove with a mathematical trick. That could be a hint that pointlikeness, fundamentally, is BS.

So they move at the speed of light (because they have no mass?) but then how come the field can be felt immediatly? Or can it not?
For example if the sun would suddenly vanish, would the earth immediatly fly away or would it take as long as light would travel from the sun to the earth?
whatever floats your goat
