What's up with the early early universe? [Galaxies we never even knew existed in the "Cosmic Dark Ages"?]

What's Up With The New JWST Findings? With Neil deGrasse Tyson

What did the early universe really look like? Neil deGrasse Tyson breaks down the new JWST [James Webb Space Telescope] finding about early galaxies and how it changes our understanding of the universe.

What is or existing model of the early universe? Learn about the dark ages and the creation of galaxies and stars. Were the dark ages wrong? How do we begin to understand this discovery and uncover the mysteries of the universe? Do we have to go back to the drawing board?

The Cosmic Dark Ages:

What are the Cosmic Dark Ages? Here’s a good description from the Kavli Institute for Particle Astrophysics and Cosmology, suggesting that, only a few hundred thousand years after the Big Bang, the universe:

… began to enter the cosmic ‘dark ages,’ so named because the luminous stars and galaxies we see today had yet to form. Most of the matter in the cosmos at this stage was dark matter with the scant remaining ordinary matter comprised largely of neutral hydrogen and helium. Over the next few hundred million years, the universe entered a crucial turning point in its evolution, known as the Epoch of Reionization. During this period, the predominant dark matter began to collapse into halo-like structures through its own gravitational attraction. Ordinary matter was also pulled into these halos, eventually forming the first stars and galaxies, which, in turn, released large amounts of ultraviolet light. That light was energetic enough to strip the electrons out of the surrounding neutral matter, a process known as cosmic reionization.

It seems, Tyson says, that those ages might not have been so dark. It looks like there might have been some galaxies in there (c. 4:30).
