This kinda reminds of when watching a flame from a a gas source, sometimes where the bottom of the flame starts shifts up and down.

If you have a pressure cooker at home, boil some chickpeas for a couple of whistles, wait 3 minutes, take the cover off, put it back on the stove and stir fast.

You will see all the steam doing the dance and shooting out like you'd expect from a black hole.

I'm not sure if only spinning Black Holes have a corona or even static ones do, that may be an interesting point to ponder.

The chickpeas stew is yum as well after (1 part chickpeas, two parts water) :)

My guess is the black hole was used for an interstellar gate by an alien ship warping into local space.
