GR is hard to understand, because it uses wrong postulates. A medium (Higgs «field») is present everywhere, so we can use it (or CMB) as 0 point.

BB is wrong theory because photons are not immortal things, they are losing energy with time, thus H0(s) are representing rates of loss for different frequencies. Our local group of galaxies is expanding, because we are falling into Great Attractor and Shapley Attractor, but it's coincidence.

QM can be reproduced and studied at macro scale using walking droplets or air bubbles in water bubble in microgravity.
