Back to some humour .. this one's getting way heavy (again) …
Armed with this new knowledge, I intrepidly decided to wade into the Hogan paper, foolishly thinking I might actually be able to begin to comprehend the Abstract at least !! He's the first paragraph: ….

A phenomenological calculation is presented of the effect of quantum fluctuations in the spacetime metric, or holographic noise, on interferometeric measurement of the relative positions of freely falling proof masses, in theories where spacetime satisfies covariant entropy bounds and can be represented as a quantum theory on 2+1D null surfaces. The quantum behavior of the 3+1D metric, represented by a commutation relation expressing quantum complementarity between orthogonal position operators, leads to a parameter-free prediction of quantum noise in orthogonal position measurements of freely falling masses.

Need I say more ???
(Looks like something you'd see on that
snarXiv (… a test for those who think they possess PhD levels of scientific knowledge !!)
I'm glad Hogan knows what he's doing .. I wonder how many others do ?
Cheers
