Physicist Taps Pop Culture to Explain New Theory of Time

In January, Carroll will release his own pop take on the complexities
of time with his much-anticipated debut book, From Eternity to Here:
The Quest for the Ultimate Theory of Time.  Armchair Einsteins will
geek out on his audacious thesis. He argues that our perception of
time is informed by entropy — the level of disorder in a system — and
that the movement from low to high entropy as the universe expands
establishes the direction in which time flows. Furthermore, he posits
that our cosmos may be a relatively young member of a large family and
that in some of our sibling universes time runs in the opposite
direction. Some others, he argues, don’t experience time at all; once
a universe cools off and reaches maximum entropy, there is no past or
present.
