Suggesting that dark matter is actually gravitational leakage from MWI ‘parallel universes’: You tell me. (But if it’s true, then since I can’t seem to find any previous serious discussion of this idea, I get to name part of it after myself, right? :) )
I have conceived of exactly this idea—so it can’t be just the two of us. Surely some people versed in cosmology can explain why the math doesn’t work out?
It doesn’t work out because then you would expect the radial mass distribution of a galaxy to be just a multiple of its observed baryonic mass distribution, rather than almost exactly what you would expect from the gravitational collapse of a thin ‘gas’ of particles that cannot self-collide.
