Black holes are a part of the universe, they don’t eat universes. They may “eat” a galaxy over billions of years. Nothing you need to worry about in your lifetime.

Appreciate this reply! The thought of what if our "universe" isn't really even a "universe"? What if it's only a "universe" to us because we don't know any better. It would be like if our universe was in actuality a galaxy....

You can “what if” anything to absurdity, you’re now in fantasyland rather than the realm of science.

I understand that, but, is the thought of our universe actually being a galaxy within something bigger would be more fantasy than science? Respect your opinion no doubt tho!

Yes! Because all gathered evidence that we have points to a single cohesive conclusion - that all matter is contained in the universe, the space between that matter is just expanding. We have zero evidence to suggest that there is anything outside of what we refer to as “the universe.”
There are certainly things outside of our light cone, which, for all practical purposes, are outside of our universe. If you imagine a flash of light from a specific place at a specific time, and that light traveling (say theoretically infinitely) outward in all directions, there will always be something outside of that realm of possible influence. Like if something is 100 light years away and it explodes the moment that I was born, and I live to be 99, the effects of that event will never reach me because nothing can travel faster than the speed of light.

Not really.
Pretty sure a lot of "what if" is involved in science.

What if you instantaneously turned into a one eyed, one horned, flying purple people eater? Still in the realm of science ?

Maybe? Science is figuring out the unknown.
I know you were trying to be extra, but impossible sounds things are proven correct all the time in science by "what if's"
