So the article mentions the theory isn't compatible with the Big Bang, and the preface to The Dynamic Theory mentions Eric Lerner, who wrote The Big Bang Never Happened (and btw also has a fusion project). Lerner has been in the news lately because he and a colleague wrote a paper predicting what the JWST would see, and posted it to Arxiv, which removed it. Then the JWST saw exactly what Lerner predicted.

Lerner's youtube channel has several videos on this, e.g. here. Basically, what JWST saw is normal-looking galaxies from a time long before standard cosmology predicts they would appear. Not only that, but if the universe is expanding, then the visual size of the galaxies will increase over time, so if we correct for that effect then it means these normal-looking galaxies were actually way smaller and brighter than normal, even though they otherwise look the same as modern galaxies.

So far, recent "debunkings" of Lerner by mainstream physicists that I've seen have been nothing but glib dismissals and ad hominems. Still looking for one that addresses his core points. I haven't yet watched the debate videos Lerner posted.
