Question: how do you know that black holes kill

Chris Armstrong answered on 15 Jun 2015:

It’s incredibly difficult to say what happens beyond the event horizon of a black hole. Which is where the gravitational field has become so dense that even radiation (or light) cannot escape. But in the lead up to that we know a process called “spaghettification” will happen. (I kid you not, that is the name of the process).

**I think we’ve seen this in stars, but if not the theory was well established before hand in less extreme situations. **

The process is driven by gravitational forces, we usually attribute a center of gravity to objects and say that gravity acts from there. Thats an approximation that works, providing the objects or gravitational forces are relatively small, but for a black hole this effect is so extreme that the difference in gravitational forces at your feet and at your head would cause you to stretch out like spaghetti.

I ain’t a doctor but that will kill you straight up.
