Comment on well?
PleaseLetMeOut@lemmy.dbzer0.com 1 day agoYes, but if you’re beyond the event horizon time becomes basically* irrelevant. You could literally turn around, look back out towards the rest of he universe, and watch all of time play out in the blink of an eye.
You know that scene in Interstellar where they land on the planet for 5 minutes, but 20 years passes for everyone else due to the planet’s mass? It’s the same thing, but a billion-billion-billion times more severe.

No, time does not become irrelevant. It’s perfectly normal for things inside the black hole. Here’s the space time diagram for our universe on the right, and a black hole at the top-left. The speed of light is a 45° angle to the top right, and the solid lines are event horizons. Notice the space-time diagram looks exactly the same on the other side of the horizon. To get back through though you’d have to travel faster than that 45° angle, which is impossible.

I’m aware of the Penrose diagram and I also watch PBS SpaceTime :)
But I was referring more to the frame of reference of our universe vs that of being inside a blackhole (assuming you could magically avoid being ripped apart by gravity). To an observer inside a blackhole, “time” on the outside would blink by almost instantly. Hence the Asterisk on basically*.
I was leading them to what MotoAsh posted. But they beat me to it while I was typing.
