One of the most outlandish new theories of cosmology is that space-time is actually a superfluid substance, flowing with zero friction. Then if the universe is rotating, superfluid spacetime would be scattered with vortices, according to physicists Pawel Mazur of the University of South Carolina and George Chapline at Lawrence Livermore lab in California – and those vortices might have seeded structures such as galaxies. Mazur suggests that our universe might have been born in a collapsing star, where the combination of stellar matter and superfluid space could spawn dark energy, the repulsive force that is accelerating the universe.
Duh! That’s not weird at all. My favorite weird cosmology is missing from the list: time is an illusion, all possible universes exist, and that includes many universes with false memories and traces of a supposedly distant past.
Then there is always "elephants all the way down…"
