It's worrying. In Z category timelines that are not also indexed as 'HAVEN', I've found black holes to appear within the CORE. This... well, shouldn't happen!! I mean, it was created by Dr. Gaster.. as I've heard from HIS followers, [NOTE TO SELF: It's the first one. The other two just mention him, but not HIS name.] Everyone else just always says "Yeah, ALPHYS created it" or that it was just always there.
The only VIABLE explanation I've found is a localized gravitational collapse. Whenever the CORE's output exceeds \(8.71 \times 10^{32}\,\mathrm{J}\), spacetime briefly satisfies \(r \leq \frac{2GM}{c^2}\). That SHOULD BE IMPOSSIBLE. The equation works, yeah, but it doesnt make a tad bit of sense. Fuck.
This is also weird. Normally - as we all know - a black hole DOESN'T LOOK LIKE THIS. Well, funnily enough, this one extends outside like a spiral. Meaning there's a simple black hole in the middle, but then 'arms' extend from behind it.
