Quanta: A New Cosmic Tension: The Universe Might Be Too Thin
A very important finding. In addition to the Hubble tension the universe might have too little matter. There are many interesting possibilities in the text. Perhaps material for further discussion? I find the suggestion that DM might decay into DE interesting and we've discussed that idea before and elsewhere. But the Planck CMB results.....

PS (edit) By too little matter both baryonic and dark matter are too little.

This is getting more and more weird.

Re: Quanta: A New Cosmic Tension: The Universe Might Be Too Thin
I think it’s going to be a very long weird ride in bizarroland before some clarity is reached.

Re: Quanta: A New Cosmic Tension: The Universe Might Be Too Thin
One can never be too thin or too tanned. Or is it too thin and too rich? Dunno, I'm not a big Wallis Simpson fan.

New physics? Please?
Any metaphor will tear if stretched over too much reality.
