What Happens When You Fall Into a Black Hole?

The BBC has an interesting recent post on what happens when you fall into a black hole. It mostly gives a rundown of various ideas about what happens (we can’t really test those ideas for obvious reasons). I don’t really know enough about general relativity to comment on the accuracy of the post, but I think they are correct when they say that if you fall into a large black hole, you don’t really notice anything, Nothing particularly special seems to happen at the event horizon to the object passing across the horizon. The more interesting idea here is that the black hole in some sense splits reality into two parts that can’t interact with one another (except perhaps through some quantum gravity effects).
