I have a book dedicated to the science behind the end of the world.
It says that speghetification is the process of been sucked into a black hole. You're entire being is stretched out 3+ miles long, and about .01 inches in width.
Yuuuuuuummmm.
Oh, and the closer you get, the slower time goes. So if you have two guys, and one gets near a black hole, he'll appear frozen to the other one that's still in a far distance. You may think he just froze, but he's been dead before time even started slowing down for him.
