An inverse Dyson sphere.

On the topic of black holes, there is a recent paper on black holes potentially converting mass into dark energy: https://iopscience.iop.org/article/10.1088/1475-7516/2024/10...

I'm not a physicist but it's interesting to think about the implications:

1. No singularity at the center of a black hole

2. Universe's expansion rate is not constant because it's blackholes powering it with matter

3. Eventually expansion slows, stops and reverses

And now my own crazy ideas:

1. Maybe the universe is a inside a black hole

2. Maybe the big bang was a result of the birth of another black hole somewhere else, and that the rapid expansion rate of the early universe was due to the a huge amount of matter converted into dark energy by this black hole

I think once we finally get this all sorted out, future humans will find it hilarious that so many people were convinced that dark matter was real and particles we could not detect made up 80% of the universe.

> That creates a problem for supermassive black holes.

I don’t think the black holes are the ones with the problem.

Can it be that black holes are mainly eating dark matter?

Or maybe they already proved that black holes consume some dark matter but at a much lower rate to explained this.
