360 Video: NASA Simulation Plunges Into a Black Hole.
Yes, I know this is from NASA, but unfortunately it is not accurate. Or at least highly, highly misleading. For one, the external universe would not disappear like that. Here is a more realistic view of what would occur. If even NASA canโt get this right, you know weโre fucked.
The below, though long, is also far more accurate.
The NASA simulation is likely botched because it did not properly account for the fact that relativity means that there is no real difference between the astronaut(s) inside and those outside the event horizon in practical terms except light can no longer escape. Most probably it attempted to simulate the view of the infalling astronaut for the perspective of the external universeโฆwhich is just wrong. And results in the misinformation seen in the NASA sim.
