Weinstein has an idea of Unified theory. His paper is just an outline of his idea. He has not worked on in any detail despite having the idea for 10-20 years. Ideas are ten a penny. It's a seller's market. Making them work in detail and as a whole is "doing the physics". As Sean Carroll has pointed out, it's better to cut the big grand idea into small solid pieces, work on them, then publish them one by one. It's this work that is missing. Weinstein is the physics equivalent of "I have this great tech platform idea, I just need someone who knows how to program to make it happen for me". He doesn't need to convince mainstream physicists to volunteer. He has money, so he could award research grants to make others take a look. EDIT errors found in his theory: --- [Guest Post] Problems with Eric Weinstein's “Geometric Unity” https://backreaction.blogspot.com/2021/03/guest-post-problems-with-eric.html https://backreaction.blogspot.com/2021/03/guest-post-problem... >Our findings are that even aside from its status as Theory of Everything, GU contains serious technical gaps both mathematical and physical. In summary: >* GU introduces a “shiab” operator that overlooks a required complexification step. Omitting this step creates a mathematical error but including it precludes having a physically sensible quantum theory. >* The choice of gauge group for GU naively leads to a quantum gauge anomaly, thereby rendering the quantum theory inconsistent. Any straightforward attempt to eliminate this anomaly would make the shiab operator impossible to define, compounding the previous objection. >* The setup of GU asserts that it will have supersymmetry. In 14 dimensions, adopting supersymmetry is highly restrictive. It implies that the proposed gauge group of GU cannot be correct and that the theory as stated is incomplete. >* Essential technical details of GU are omitted, leaving many of the central claims unverifiable.
