"Reinventing cosmology: New research puts age of universe at 26.7 -- not 13.7 -- billion years"

'Our universe could be twice as old as current estimates, according to a new study that challenges the dominant cosmological model and sheds new light on the so-called *impossible early galaxy problem.*'

"Here, as a last-ditch effort, we point out that disregarding the large angular scale polarization obtained by Planck, which allows for significantly larger values of the matter clustering parameter σ8, could lead to better agreement between Planck and JWST within the ΛCDM framework."

*Last-ditch*: a desperate final attempt = If this explanation doesn't work, they will give up #ΛCDM 👍

Here's a paper from all the way in 2014 mentioning differences between #MOND and #LCDM, and right in the summary is 'MOND predicts structure formation more quickly'. The #paper is well worth a read.

"Warm Carbon seems to have increased suddenly in the Early Universe.
The study adds another piece to the puzzle of the history of the universe."
Did it increase suddenly, or was it already there 800 Myr earlier?

Everybody writes "JWST has not killed the cosmological model" and goes on to write a paper proving that #LCDM is inadequate to describe JWST observations.
So, which one is it?

"The shaky foundations of cosmology" | Bjørn Ekeberg
🔗 https://youtu.be/XmzulJsGtZ4

As a scientist I make the metaphysical assumption that the laws of physics are the same everywhere.
This eliminates the impossible problem of having to decide if the laws are different somewhere else, or if our laws of nature are just wrong. (A very good question here https://youtu.be/XmzulJsGtZ4?t=896)

@astrocorus "Even if only half of Yan’s selection turn out to be nearby #Galaxies masquerading as distant ones, the latter number would still be unexpectedly large. “Our previously favored picture of galaxy formation in the early universe must be revised,” he says."
As usual, @startswithabang adopts the narrow, biased view of #LCDM #Cosmology . Instead of beer for his bet with Yan, how about writing a real article to apologize for misleading the public?
