That is very interesting. As we all know from Interstellar (
) gravity can communicate accross the dimensions. What i want to know is, if all the matter is being attracted to one point, then would it be a different point than where the matter is entering our universe (ie white hole that i have speculated)? Because i believe the universe is still expanding, from which we can infer matter is entering it still. I would imagine that our birthing multiverse would be closest at the point of the "white hole" so would that not be the most gravitational area?
...or could it even be an alien multiverse who's gravity we are feeling? Maybe it is in very close proximity to us?
Or maybe matter isn't entering, but spacetime is expanding. (Not sure if that counts as matter).... Perhaps we have separated from our birthing nultiverse completely and are a floating bubble (or brane or whatever) and are still detecting our host's gravity. But why the expansion? Is it because an object in motion stays in motion? If spacetime started expanding when it was birthed, what would stop it from doing so if there is no medium? Gravity within itself? Then why is it accelerating?
