So, in principle, you could be in a

0:01

large enough black hole, you wouldn't

0:03

know. We could be in a black hole right

0:05

now. The event horizon is not a

0:07

particularly violent place for you. You

0:09

can calculate the tidal forces, and

0:10

they're not particularly big. Or rather,

0:12

for large black holes, they're not

0:13

particularly big. For a solar mass black

0:15

hole, they would be pretty big, and it

0:17

would be pretty painful for you. You'd

0:18

find that your feet are being attracted

0:19

to the black hole much more vigorously

0:21

than your head is, cuz they're closer,

0:22

and you end up getting stretched. But if

0:24

I take a big enough black hole, you

0:26

wouldn't notice anything funny happening

0:28

whatsoever. When you cross the event

0:29

horizon, uh you are doomed. You are

0:31

doomed, but you are not dead. Uh you are

0:33

only for sure dead once you hit the

0:35

singularity and get spaghettified, get

0:37

mangled by the by the tidal forces. But

0:39

for a large enough black hole, uh you

0:41

can be doomed uh and not even know it.

0:43

You could live out your life, you could

0:44

have descendants, all of whom live

0:45

inside the black hole, and only once you

0:48

really approach the singularity do the

0:49

tidal forces get strong and kill you.

Interactive Summary

The video explains that crossing the event horizon of a large black hole is not necessarily a violent experience. While solar-mass black holes cause extreme tidal forces that would destroy a human, larger black holes allow an observer to cross the event horizon without immediate harm, though they are ultimately destined to meet the singularity.
