@normsmusic Everything about black holes is interesting. That they have found a possible connection with cosmic expansion is doubly interesting. We will see where this goes. There's a point in time near but after the cosmic beginning when the expansion rate changes suddenly. Nobody knows why. Perhaps this discovery is related and will finally resolve the mystery.
@normsmusic I just read the article you posted. I had read a different article yesterday about it and was hoping for a little more detail. It's probably just the article writer but I'm not seeing causation. I'm only seeing correlation between the size of black holes and the cosmic expansion rate. Have they definitively shown causation in the original paper?
