Reply to comment by Tjam3s in Black holes may be quietly generating the force that is tearing the universe apart, experts say by dr_gus

This is kinda where "common knowledge" leads you astray. For scientific research even when correlation is not causation, it's usually jumping up and down and pointing to where you should be looking. It's fun to to point out piracy and global warming to be cute, but when you find close correlation you should be digging into it until you find a way to dismiss it.

I suppose the part they seem to assume is that the black hole is the cause for dark energy, but without actual study into the real cause for the correlation.

It might be the other way around with the expansion of the universe causing the growth, or it may be an indirect mechanism being the cause for both of them.

The assumption that the black hole is helping cause the expansion is what I was digging at.

I just listened to a Lex Fridman podcast with one of the authors and it didn't seem to me to be as much of an assumption as proposing a possible mechanism that needs to be figured out and then tested.

Cause in and of itself is a human concoction. You cannot actually prove that anything is caused within the universe. It could very well just be that the information we observe simply presents itself in a specific mandatory pattern and order and our brains totally fabricate the concept of causality.
