yes
Might make you rething that.
Nope. Different concept there. Think black holes. If gravity was not faster than light, then light could escape a black hole. At least we'd see the light that is coming around it. Since Black holes eat up all light--including the light that is between the hole and us--that means that gravity is faster than light.
“... that means that gravity is faster than light.” Um, kind of the same as saying apples are sweeter than nails are hard.
