I don't know about the idea of turbulence but modified gravity is serious science.
It is just not the preferred explanation right now. An important reason is that AFAIK, none of these theories are currently able to match the observations without the dark matter they intend to eliminate.
Two galaxies collide. The dust stops, the dark matter keeps going... it isn't looking good for MOND.
I'm no physicist, theory was developed while doing Einstein inspired imagination visualization/simulation of the big bang. I know it's probably so wrong in so many ways it's not worth a normal physicist to respond to, just thought I'd share.
If I were correct, which I'm probably not, it would mean there are no "primordial black holes" that existed since the moment of the big bang, but rather as time went on the black holes were created and increase in number (also being part of what causes this universe to expand)
If you want things to be received as a thought experiment, call it that up front. You'll get people thinking and talking about it. But the response you received is in line with what the word "theory" means in the scientific community.
Not sure how much more clear it can be... If the single word "theory" misapplied can't be seen through by such intelligences well what else is there to say than I'm sorry and I'll never mention it again. I'll stick to the theories I'm good at.
