This beautiful little book is as much philosophy as it is physics. Drawing on sources as diverse as Hindu, Buddhist, and Judeo-Christian traditions, ancient philosophers, Newton, Einstein, thermodynamics and quantum physics, Rovelli explores humanity’s intimate relationship with time, and the scientific pursuit to pin it down. Rovelli illuminates his synthesis with lyrical, imagery-laden prose, and provides ample references and notes in the inevitable event the reader is provoked to learn more.

One of the ideas that struck me was his suggestion that the Universe consists of events, not things, essentially that nothing is permanent. I woke up this morning singing the following Talking Heads lyrics:

Heaven
Heaven is a place
A place where nothing
Nothing ever happens

Maybe heaven is a black hole?
