Main Question or Discussion Point

hey

if you have like 2 electromagnets a few light years away from each other

lets say if u turn them on at the same time (ok lets say they're very very powerful)

will they react to the new magnetic field instantly , or will we have to wait a few years for the photons to go from one electromagnet to the other


if answer : instantly :
how is this possible ?

They will have to wait for the photons to traverse the distance.

Which brings up a next point. Nothing is instantaneous.

Oh- electromagnets. I thought this was going to be about applying electricity to romance! I'm disappointed.

but hey

is gravity instatanuous or do we have to wait for the gravitons to travel the distance ?

if not instatanous :
is the graviton speed equal to c ?

So if we can find out what what "Nothing" is made of we could travel faster then light.

The force of Gravity travels at the speed of light.

I think it would be more rational to just try to get at least to a tenth of c , before we try that
