I started by asking what Einstein did not know, but we know today. Then asking Claude to act as Einstein and come up with a novel theory, based on this output.
Then, iterating for several hours: outlining, writing chapters, improving, acting as a professor to review, acting on this feedback and adding citations. I know nothing about the math presented here.
From a quick scan, this reads like a very pure example of crank nonsense. Unified theory of everything with sparse and incoherent math. Lots of describing how revolutionary the theory is, very little actual theory
