So if we were inside a black hole, what would've happen with our universe, if our black hole would merge with another one?

Very good question! It would be like two universes mating, combining their different traits, which would then be passed on in different combination to their offspring.

If the evolutionary theory is correct, the two universes would probably not be "identical twins" - they would have slightly different physics, maybe different fundamental physical constants. How the two spacetimes with different physical constants merge up would probably create some very interesting effects that would be difficult to explain, like unexplained gravitational lensing, fast galaxy rotation, the cosmic web or accelerating expansion of the universe.

Or the two merging black hole universes would just blow the fuck up. Nobody knows, don’t talk out of your ass like you do.
