One very important difference between the big bang and the interior of the black hole: Within the event horizon of a black hole, there is always a singularity in your future. In our universe, that singularity is in our past.

One interpretation: the big bang theory describes a white hole -- the time-reversed version of a black hole.

Einstein-Cartan Theory (https://en.m.wikipedia.org/wiki/Einstein%E2%80%93Cartan_theo...) introduces a torsion term to General Relativity’s field equations that is not incompatible with observations and provides both an avenue for explaining the cosmological constant (https://arxiv.org/abs/1607.01128) and “big bounce” motivation for the beginning of our current universal epoch (https://arxiv.org/abs/1512.06074).

Imagine our universe is contained within a blackhole.

If time and space invert at the event horizon, could it be that the Big Bang was the event horizon of our black hole, that we are forced forward through time by the pull of our black hole interior, and that the expansion of the universe is actually just metatime passing, and as we move through space we are actually moving forward and back in metatime, with the expansion of our universe being an expression of increasing constraints due to metatime’s metaspace as we get closer to the center of our blackhole?

I could imagine that the “Big Rip” is what we experience when we asymptotically approach the singularity. The strangeness of black holes could mean that falling into a single point is actually experienced as space flying apart faster than light.

Yes.
