The chart is the work of Dr Charles Lineweaver

That is an amazing name for a scientist doing charts

Imagine if it is true that the known universe is the center of a very large black hole. Which then suggests that even small black holes hold universes in their centers. I mean why not, right? Which begs the question that if we can create black holes in a lab, does that mean we were able to create (and destroy) universes too and just not know it?

But, would any black hole "come with" a universe embedded or is it a property of absorbing mass?

The extent of my knowledge of astrophysics and relativity are around the size of the next comma in this sentence, but wouldn’t a great deal of time pass “inside” such a black hole such that a “universe” could rise and fall in what would seem to us as just a few microseconds due to relativistic effects?

The blackhole universe would seem to move infinitely slow to us and our univers would flash by in an instant to them...

Black holes still have finite mass, and can be lighter than Earth.

Wouldn't it be the other way around, if anything? Things closer to a black hole experience time slower.

This isn't a new theory, the title is kind of clickbaity.

Maybe you should read the article where this is addressed.

Ultra simple conclusion any high school senior could come to knowing basically fuck all about relativity and weed ... oh they have data now? this is super fucking cool.

So close but so far
