A 'Hubble Crisis'? New Measurement Confirms Universe is Expanding Too Fast for Current Models - Slashdothttps://science.slashdot.org/story/25/01/19/0422230/a-hubble-crisis-new-measurement-confirms-universe-is-expanding-too-fast-for-current-modelsz komentářů:
Our models would allow for the possibility that Dark Matter arose after the Big Bang, possibly a long time after, and that Dark Energy arose long after the CMBR.
Physicists have considered these as possible explanations for anomalies in the distribution of Dark Matter, and the existence of the Hubble Crisis.
If Dark Energy appears late, then you would indeed have two different values for the Hubble Constant. And our models of Dark Energy certainly allow that to be a possible explanation.
You'd have to explain the physics behind it appearing, and that may well end up an impossible hypothesis, but, for now, it would allow the universe to have different expansion epochs, played under different rules.
