But that balloon theory doesn't really do it for me as they left out gravity and the effects it has on galaxies.
I think a theory that gravity and massive black holes are pulling galaxies apart is better than the total unexplained balloon theory.

black holes trap light because of the wave-particle duality nature of the photon as it travels by the event horizon, they don't cause light or mass to accelerate past the speed of light, they can create a lensing effect though.
My the point was that people take the image of the night sky as an image of what the universe looks like while the significance of relativity on simultaneity dictates that the universe has to be very different than we perceive it to be, then again can you really define something as having happened before the gravity waves reach an observation point? yeah I know that was the background radiation, i didn't mean to post that image.
and light-speed helps dictate the shape of the universe because gravity waves travel at c and thus a change in mass through antimatter interactions can only effect a certain point in space once the gravity reaches an observable point.
