The Universe Is A Shuttlecock

PostThu Jun 06, 2019 3:59 pm

Hartle and Hawking’s proposal radically reconceptualized time.
Each moment in the universe becomes a cross-section of the
shuttlecock; while we perceive the universe as expanding and
evolving from one moment to the next, time really consists of
correlations between the universe’s size in each cross-section
and other properties — particularly its entropy, or disorder.
Entropy increases from the cork to the feathers, aiming an
emergent arrow of time. Near the shuttlecock’s rounded-off
bottom, though, the correlations are less reliable; time
ceases to exist and is replaced by pure space.
