>>51118788With your video in particular, it is worthy to note that it models the Doppler effect of the accretion disk around the black hole semi-well: The stuff moving towards you (the right side of the appearing brighter than the stuff moving away from you (the left side)
However, it is missing the redshift effect on the left side.
Its a very pretty video, the only reason why I didnt choose to use it is that it does not show the actual crossing of the event horizon.
This one is also cool
https://www.youtube.com/watch?v=_AiJpvergBISince its something that is not often thought about, and took me a long time to realize; with a black hole with an accretion disk, you see a band of light surround the event horizon on its top and bottom. Afaik, this is not because there is anything orbiting the black hole there, you are seeing the light from the accretion disk behind the black hole bending around the black hole on both of its poles, making it appear as if there was stuff there when there isnt.
I personally find that really cool.
