We deal with mainstream physics here. Questions about the general correctness of unpublished personal theories are off topic, although specific questions evaluating new theories in the context of established science are usually allowed. For more information, see Is non mainstream physics appropriate for this site?. I can usually follow the basic ideas of a theory, but Weinstein's Geometric Unity theory is completely incomprehensible to me. It leads me to suspect that it is high level crackpottery, but he seems to be respected. Does anyone actually understand what he is getting at? And does he have any actual equations that predict something or do something?
