Reality is Not What It Seems
The Journey to Quantum Gravity
Carlo Rovelli 2017 . Cedar Mill 503.143
Author of "Seven Brief Lessons on Physics"
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 ... and what is k(co-moving)?
