"This reality splitting thing sounds wrong. I've never heard of it."
It's a strange scientific truth filtered through at least one scientist filtered through at least one journalist filtered through at least one editor. The reality is stranger... even if there's no firewall, there's still only one reality, with all the observers seeing all the different things.
As for your 2, yes, it is likely there isn't a single black hole in the universe that meets our criteria for being able to "safely" fall into it, but at least in theory such a beast could exist, and barring any other unexpected existence failures, such a beast may exist in the far, far, far future. There's a lot of future and most of it is pretty boring....
