Spaghettification was one of my unexpectedly favorite lessons when I took a general relativity class, but that was a solid decade ago. edit: IIRC, the math said that except for the case of very large, "supermassive" black holes, the human body, and pretty much anything else, really, would be ripped apart at the molecular scale soon before, during, or after its passage through the event horizon. Hell of a way to go.
It seems like the spaghettification process could provide a good playground for reconciling relativity and quantum mechanics theory, but it's impossible to send the results from any experiment back out across the "surface" of the black hole, i.e. the event horizon. Bummer.
But don't despair, perhaps if you found a small enough black hole (not sure how exactly how small it'd need to be), you might could get yourself spaghettified outside of the event horizon! That is, if you managed to survive the intense radiation environment. Lucky you.
Damn, now I'm wondering if all the blue-shifted cosmic microwave background radiation would kill me on the spot, or just give me radiation sickness.
