"The increase of disorder or entropy with time is one example of what is
called an Arrow of Time, something that distinguishes the past from the
future, giving a direction to time. There are at least three different
Arrows of Time. First, there is the thermodynamic Arrow of Time, the
direction of time in which disorder or entropy increases. Then, there is
the psychological Arrow of Time. This is the direction in which we feel
time passes, the direction in which we remember the past and not the
future. Finally, there is the cosmological Arrow of Time. This is the
direction of time in which the universe is expanding rather than
contracting.... Our subjective sense of the direction of time, the
psychological Arrow of Time, is determined within our brain by the
thermodynamic Arrow of Time. [We] must remember things in the order in
which entropy increases. Disorder only appears to increase with time
because we measure time in the direction in which disorder increases."
-Stephen Hawking
Not to compare DQ to entropy, but replacing the disorder/entropy references
in the preceding passage with DQ paints a nice picture of how time relates
to the MoQ. Maybe.
