Quantization of time and the big bang via scale-invariant loop gravity

13 Nov 2019 Wang Charles H. -T. Stankiewicz Marcin

We consider the background-independent quantization of a general scale-invariant theory of gravity with matter, which supports a conserved Weyl current recently suggested as a natural flow of time. For scalar-metric systems, a conformal class of Ashtekar-Barbero connection variables is constructed, which can be quantized using spin networks... (read more)
