Maybe space is so dark because we live in one massive black hole

If the universe is closed and everything within it will all collapse back together in a “big crunch” far in the future, then we are indeed inside the event horizon of a huge black hole right now.

I have long wondered - how could we tell the difference between the Universe expanding versus contracting into a massive universal black hole with its event horizon being the Big Bang?

Objects further “down” the black hole from us would seem to be receding from us because they are travelling faster than us.

Objects not as far “down” the black hole seem to be receding from us because we are travelling faster than they.
