Hi PF!

When Einstein was done with his General theory of Relativity, he was trying to build upon this theory, through different approaches, like the Kaluza-Klein theory, to try to build a classical theory of everything, which was purely geometrical. Since this wasn't successful throughout the many approaches tryed, I was wondering, if any life was brought back to a purely geometrical approach to GUT theories? Specificly a theory where the forces are described through curvature of a geometry (much like in general relativity).

I seem to notice a buildup of papers like this: Detecting single gravitons with quantum sensing. (OK, old one.) Toward graviton detection via photon-graviton quantum state conversion Is this akin to “we’re soon gonna put string theory to the test”, or are these legit? Mind, I’m not expecting anyone to read the papers and explain them to me, but if one of you educated people already have an opinion I’d like to hear it. If not please ignore me. EDIT: I strongly suspect it’s bunk but...
