I don't care how smart they are. That wasn't a real black hole. It didn't follow black hole physics.

Also, Sayaka did in fact travel as a ray of light inside H.N. Elly's labyrinth. And EoS showed that Magical Girls can't transform into witches anymore, and Rebellion's Law of the Cycle displayed that when Homura and Mami fought and their soul gems didn't wear out at all. Considering that fighting on that scale at first would make their Soul Gems darken up, that shows that the Soul Gem probably can endure a lot more now. Maybe it's not limitless in every sense of the term, but it's a HUGE buff.
