Interesting, thanks. That does sound like you could tell from inside if you there or not.

I'll have to read up on that, I always had the vague sense that on ~finite scale of time there existed a region of space where you couldn't really tell the difference if you're inside of a big enough black hole or not.

Which sounds like I'm probably just wrong.
