It doesn't slow light but it does bend it and I have a hypothesis that it does so because it's "faster" than light----sort of. Think of a black hole where light emitted from its center would b pulled back down into it.

If u tie two toy jets with the same mass together in zero gravity n they pull apart at the same speed they'd move nowhere. Now if jet A  travels just a meter/s faster jet b will begin to change its trajectory as it's now being pulled in the opposite direction.

Of course I could b wrong seeing as I know absolutely d*ck about physics but thinking about the laws of force here it seems gravity can reach speeds higher than c relative to its quantity.

This form can only be applied if u think of gravity as a wave like light. Now if u think of it as a force (which seems a lil more common sense[ish]) then gravity isn't faster than light but a force strong enough to disrupt an object with such a speed. But again, as force is directly relatable to speed one can argue the force behind gravity can pull faster than the speed of light given a big enough quantity of gravity (of course in this case mass and other variables must be factored in).

Again I kno d!ck about physics so this is purely abstract thought but u gotta admit it makes (common) sense as an abstract thought, no?
