...until we will get to test it in practice.

Actually, I believe it may be a futile thing to approach experimentally. We might try making successively large and larger treks into the gravity well, but at some point, I think the blueshifting of CMB alone might kill people. I'd have to do the calculation, but again, my instinct is that this would favor larger black holes being more survivable, as you'd get less CMB flux at the event horizon (for something of finite size, like the human body). Ya know? Plenty of other problems too, like time-dilation so extreme that the universe ends while you're down there poking around.

They don't know it yet, but I'm going to pester some theorists next week about that. :D

I'm interested in hearing how this pans out.

Joke about Contact or something else? I've never watched it. I can't put my finger on what it is, but there's something about Jodie Foster that made me unable to watch movies with her.

Haaaa! I forgot McConaughey was in Contact, as a priest. No, I was talking about "Interstellar", which I somehow managed to enjoy a little.
