The Labyrinth of Time: Introducing the Universe by Michael Lockwood

bill_desmedt's review against another edition

3.0

A curious book: for nine tenths of it, Lockwood staunchly supports Einstein's "loaf universe" view, according to which the future is as determinate as the past, together with the "Principle of Sufficient Reason," according to which even a time traveler can't change the past because his/her visit is already part of it. Then he veers off into a discussion of how time travel *could* change the past (hence, the future is *not* fixed) based on his (many worlds) interpretation of Everett's non-collapse quantum mechanics.

I'm confused, to say the least!
