How does M-Theory deal with space time? One of my friends said something like it verifies it. Is anything known about it?

I'm not sure a lot is known. The various string theories--which are M-theory dimensionally reduced in various ways--have to have a spacetime given to them, as opposed to the background falling out of the equations like how Minkowski spacetime is a solution of GR.

11d supergravity--the low energy limit of M-theory--has an SO(10,1) type spacetime. But who knows what's going on in M-theory.
 

Thread 'Detecting Gravitons?'

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...
