My bet is on timescape as it doesn't use any unknown magic. Just requires applying GR correctly instead of in the simplest conceivable way that CDM does. A lot

A lot of things might clear up once you remove the assumption that Big Bang was true begining of matter, energy and time, with everything isotropic instead of just temporary state of high temperature (kinetic energy) and density with its own internal structure.

- scotty79 2y agoAssuming zero is no less magic. We have the timescape that we have because of what the distribution of mass and kinetic energy is. And why the matter is distributed like that is because it never used to be isotropic, just dense and hot. Asking why this specific distribution is what we got is like a grain of sand thrown up by exploding landmine asking why it observes this specific distribution around itself. By the way it would observe a Hubble law because faster moving grains (relatively) would move farther away during the time that passed since the blast. The correct answer to question about why it's this specific distribution definitely isn't assuming that before the blast there was no space, time or matter even though that could be the simplest mathematical thing to model.
