Why can't black holes be worm holes?

That's a very subtle question. In theory, if you assume a black hole which has existed forever and take a close look at the maths, it will contain a wormhole. Especially when it is electrically charged or rotating, the singularity in the middle will in theory be spread out and turn into a horizon leading to a parallel universe.

Black holes which form e.g. from star collapse will however not form the region inside it which would lead through a wormhole.

One can however simulate what falling into a rotating black hole would look like:

In this vid you fall into a charged black hole and then through various horizons marked by different colors in the small map, and the flashes are when you see your old or the new universe at superhigh blueshift (which would in reality probably vaporize you), and in the end I think we come out at the new universe, but looking back at the hole. The gridlines are just to illustrate the distorted geometry of the event horizon.

That this looks so crazy scifi is even cooler considering that this is a mathematically accurate simulation.

This is what the mathematical structure of such an eternal electrically charged black hole that we just fell into looks like: The wavy line is i think the path you would follow if you jumped in, e.g. stating in the patch called "Universe".
