The only issue is the nature of electric charge - what is it really, i.e. can it be reduced to gravity? can it be just an emergent property of energy/spacetime? And in particular the repelling property of the charge which at first seems to not exist for gravity - then where it comes from? I think it is some spin based effect along the lines of the…</p><p><a href="https://hackerpaper.kaipfister.de/p/1901.02894/">Paper and discussion history</a>.
