I was thinking about if Black Holes are 4th dimensional.
I know that spacetime inside a black hole scrambles (not sure if this is the correct term) very fast to produce more space, like a bag that is always getting deeper by the second, it's also why you cannot escape it.
Furthermore, as the Einstein-Rosen bridge idea states that black holes extend into the fourth dimension, at least to my understanding, and it's why you can entangle them via the 4th dimension, a wormhole.
To segway to my conclusion, would it be rational to think that a black hole is a 4th-dimensional sphere because of the Einstein-Rosen bridge theory, but without the entanglement? Just one black hole.
I apologize if this is obvious or a "stupid" question to ask. PS: I am not a math guy, so please try to avoid a mostly mathematical answer.
