What Would You See Inside a Black Hole? | General Relativity

[Randy Subers]

TL;DR Summary

What does it look like looking out from inside a black hole?

For this assume General and Special Relativity and not some of the quantum enhancements that have been proposed for them. If I were an astronaut who just crossed the event horizon on a galaxy center type black hole (big enough so I would not be immediately spaghettified) and avoided the accretion disk and any jets on the way in and looked outward (away from the singularity) just after I crossed the event horizon, what would I see?
A more or less normal star field?
A severely distorted star field?
Pure black? or
Something really strange?

Also if I then looked around my spacecraft would it look normal (pre-spagettification)?

I suggest a forum search. Topics has been brought up many times.

just after I crossed the event horizon, what would I see?

Andrew Hamilton has created a great series of videos on this (not just the specific point right after the astronaut crosses the horizon, but the whole infall process, from far above the horizon all the way through down to the singularity):
