Too-Old Galaxy Upsets Cosmological Models

A paper published today in Nature details findings using new
data from the James Webb Space Telescope (JWST). The results
find that a massive galaxy in the early universe—observed
11.5 billion years ago (a cosmic redshift of 3.2)—has an
extremely old population of stars formed much earlier—1.5
billion years earlier in time (a redshift of around 11).
The observation upends current modeling, as not enough
dark matter has built up in sufficient concentrations to
seed their formation.

. . .

Observations often up-end cherished theories.
The better the instrumentation, the more
unicorns fall.

The current thinking was that such long-developed
galaxies came much later in the timeline - and
required lots of "dark matter" to kick things off.

Now, apparently untrue.

STILL suspect "dark matter" is the new 'luminiferous
aether" ... a stand-in idea for something not yet
understood.
