Yes, very interesting. But nothing new as far as solved puzzles.

I always thought the event horizon was that movie with Larry Fishbait.

"before you quickly vanish forever into the singularity"

That's a shame, I was hoping the ride into the singularity would be a slow one so I could take some notes and perhaps come up with a short essay on the experience.

Question #6: How did they get one of these inside Sarah Palin's head?

the last thing you see is... the ring (of all the light in the universe)

I gotta to disagree with the conclusion that you disappear forever... if you were bad you go to some sort of robot hell, if you are good you go to Kolob... video proof:

Spaghettification, anyone?

(3:09) Electro-Agnetic Radiation?

What would happen if you had a really long arm, that was VERY secure on one end and the other end crossed the event horizon (for matter, not light). Would the arm just disappear from that point, like it went through a portal? Does my question even make sense?

Your arm would be pulled apart by tidal forces long before that point simply because it is so long.

Supposing that it weren't, you wouldn't be able to pull back without losing the part that passed the event horizon, and you wouldn't be able to feel anything either beyond some point (the neuro-chemicals bridging the gaps between the neurons would be having a tough time crossing the gap). So for all intents and purposes:

Don't touch a black hole, you don't know where it's been!
