“If black holes were of a 3d construct, then it is feasible that we should have seen a tail end of one by now, but we haven't. This leads me to believe that black holes are actually flat. We only perceive them as having depth, just like the 3d paintings that we see around the world. This then would also lead me to believe that there is no outlet within this universe unless we do don't recognize the exit mechanism.
A whirlpool has depth and volume, but say if it didn't, then would that too be a black hole within a water world?”
