Sabine Hossenfelder presented: Can we please agree what we mean by “Big Bang”?
Quotation of Sabine:
This is a very common misunderstanding, which comes about because we are used to think of gravity as matter affecting other matter, not as matter affecting space. Matter attracts other matter, but matter (of any type) causes the universe to expand
IMHO, the universe is contracting simply by a different new view on the Hubble redshift, originated by the frequency reduction ( redshift related) around much more proliferated dark matter black holes than cosmologists calculate with. .So the tired light hypothesis is now based on ark matter black holes!
This means that redshift is good for distance observation, but not for receding galaxy speed, at long distances!!!
