Gravity and time come from every black hole. Neither of those are "things" in the sense that they aren't matter. So don't think I'm saying that you are any kind of wrong. Perhaps "thing" might be to vague to be technically accurate, though.

Everyone here seems oblique in a vision of nothing in perspective, though. Come on, where do you think a big bang came from?

There's a cap limit to the size of a black hole because it will pop. Moreover, "The" is rather an inappropriate reference to a big bang. You might say "our" but infinity doesn't mean what you think it means. Not due to any "limit" but due to math through adjacent dimensions you're only just start to deduce the "obvious" nature of and think to look at. "How" is a whole other Giggle Maestro.

If you need to understand how many dimensions there are...then you will never stop looking. Infinity is way more than we can but get a notion of.
