Doesn't matter what's in a black hole, because it's not observable. That
means antimatter black holes would behave just like matter ones. Thus
I-masses are still nonesense.

At that point quantum mechnics takes over and everything tunnels out in a
split second.

Any REAL physicists want to comment on that?
