Hi, has anyone tried to build "quantum GR", using the expectation value of |Psi(x)> as a "quantum ruler" and |Psi(t)> as a "quantum clock" to build up the idea of a "quantum metric"?
 
Physics news on Phys.org
What is |Psi(t)>? How do you calculate it? Can you show an example?

I came across the following paper by Mir Faizal, Lawrence M Krauss, Arshid Shabir, and Francesco Marino from BC. Consequences of Undecidability in Physics on the Theory of Everything Abstract General relativity treats spacetime as dynamical and exhibits its breakdown at singularities‎. ‎This failure is interpreted as evidence that quantum gravity is not a theory formulated {within} spacetime; instead‎, ‎it must explain the very {emergence} of spacetime from deeper quantum degrees of...
