First, not to bash... plz... do NOT take it that way.
Having personally studied the physics to the best of my research for years, I can honestly say that (following with Okum's Razor "forgive spelling") there is no "hole to the "Black Hole" model. It's about the same as such things as a neutron star, quasar, pulsar, and similar entities. The shear magnitude is the only relevant difference. It's still a huge great (un-imaginably dense) ball of "something". This huge entity is so dense, light doesn't escape unchanged, and just like you can warp a window over a stage with a perfectly good lightsource behind it, so much that it shows a definite black spot in the middle, so too can this "black hole" phenomenon so drastically alter light's travel through space, especially for being so far distant from the earth.
On the quantum level, it seems (to me) to be easier to believe we are simply losing track of particles and waves as they emanate from our reactors, rather than the possibility of them actually being produced from nothing, or reduced to nothing. Fundamentals in physics are restrictive againts that, and I would offer that those principles still stand.
Think about this for a moment, PLZ...
If nothing could escape a black hole (as so many advocate)... Then how is it that gamma is blasted across the galaxies every time a black hole "eats" something? If nothing can escape, and yet the black hole is the source, why all the gamma? I think there's something more like a gravitationally induce fission reaction caused here, myself. It's not the totalitarian end-all of existence, but something just close enough to be often and easily mistaken for it...
Of course, it's only my best suggestion (if not so humble)... lol
Happy to converse (at least from time to time on the matter)...
Your animation has it's own style, though I might caution that you should take a little more time and make something more fluid. (the geeks of the world would rejoice in that)... But if this is a style pick, rather than your limit as an animator, do as you will. It's informative, and at least mildly entertaining...
Just trying to help... at least where I can.
