I found this very interesting 5 dimensional theory that treats mass density as a 5th dimension and was created by a nuclear physicist that worked at Los Alamos National Labs. He was allowed to work on his theory for half his time he was there and published numerous technical papers concerning it. He even has a technical paper on designing experiments to test the theory in which he is an advisor created at the Air Force Space Technology Center. One of the most interesting predictions of his theory is a form of fusion that the standard model says is impossible that would make fusion energy far easier to attain. In a nutshell he predicts properly aligning the spin of hydrogen can lower the amount of energy necessary for a form of usually very rare fusion into helium to take place. Not only does this lower the energy requirements, but it it's aneutronic which means it doesn't produce radiation. I wouldn't have believed the claims myself if it wasn't for the fact he was a nuclear physicist with high security clearance and employment at LANL (he is currently deceased.)

Einstein was aware of this theory, and as far As I remember reading about it he thought it was interesting and worthy to investigate.

I don’t know why it stalled.

I’m no scientist but we have 3D, 4D cinemas, why not go for 5D!

Please reply to OP's comment here: https://old.reddit.com/r/Futurology/comments/ym05le/exploring_5_dimensions_the_dynamic_theory_of/iv13qvg/

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.
