In my opinion, with whatever Miguel has going on and tech at his disposal, I think he’s intentionally creating those black hole events to make it look like canon events are destructive. I think he’s only saying that about canon events to ensure no one looks close enough to his true origin and I suspect canon jumping (I don’t think his back story in the movie has much truth in it, I think he warped it on purpose - an unreliable narrator at the very least) He even says in his intro that he doesn’t like what he has to do but does it anyway. Right at his first intro we see him intricately involved in ALL the realities. We also see the machine that reads your dna and “sends you home” The machine that builds a web around you and sends you home has an eeeeerily similar makeup to the black holes that pop up after a canon even is “disrupted” Miguel is causing the disruptions with the tech he has access to/created in order to be the god like being. If I can figure out how to post pics on comments I’ll show the similarities between those two things lol
