I was reading a web page about black holes colliding when galaxies collide.

It said something about the gravity waves compressing Space/time so I figured light traveling through one of these ripples or waves would get from a theoretical point "A" to a theoretical point "B" of normal space time faster than c because of passing through the fold created in space time.

Perhaps the light even moves briefly into another dimenson.

Before the fold was created the distance the light had to travel to get from "A" to "B" was "X" but after the fold the distance was decreased so for a brief period of time the photons actually traveled FTL relatively speaking.

I suppose the light would have to be moving basically in the direction the ripples were coming from in order to pass through them because if they are both traveling at c in the same direction then the photons couldn't catch the ripples.

So imagine ripples created by throwing a stone in a pond then imagine a beam of light passing over the surface of the pond.

Molecules of water on the back side of a ripple are now closer to the molecules of water on the front side of the ripple, the light beam passes through the ripple and actually gets from the molecules of water in the front of the ripple or point "A" to the molecules of water at the back of the ripple or point "B" faster than it would have without the ripple.

Or you could draw it out on a piece of clear plastic.

Write an letter "A" at one point on the plastic and the letter "B" a few inches away.

With the plastic flat on a table the time it would take for a photon of light to get from point "A" to point "B" is equal to "X"

Now push the paper so that a fold is created between the "A" and the "B".

The value of "X" is less because the photon has less distance to travel to get from point "A" to point "B" because it travels through the fold.

So this is FTL, the photon moved from point "A" to point "B" in less time than it would've if the ripple had not been there.

Of course this is all relatively speaking.
The Photon itself did not ever exceed the value of c however in essence it still moved from point "A" to point "B" at a faster than light pace.
