Reality is Not What It Seems

Carlo Rovelli 2017 . Cedar Mill 503.143

Idea is that spacetime is quantized, connection graphs between nodes at Planck scale. "Big bang" is "big bounce"

p059 Maxwell's equations: dF = 0, d*F = J (?? divergence and curl of "field" ?? )
p157 John Wheeler audio
p182 "time does not exist" at the Planck scale, time is relational at large scale
p220 Possible loop quantum gravity prediction of background radiation spectrum
- graph vs. k_(co-moving) which ranges from 0 to 20
- A. Ashtekar, I. Agullo, W. Nelson ... probably fig. 1 of Quantum gravity extension of the inflationary scenario , 2012
