Time's arrow unraveled: entropy guides cause, memory, and the future through the universe’s growing disorder.
Entropy’s arrow not only orders chaos; it defines time’s flow as the universe climbs from lower to higher information states.
Time’s direction may hinge on quantum decoherence: observers force a single history by entangling with their environment.
The past exists as a memory imprint in spacetime; the future doesn’t predefine its own quantum states until measured.
Some physicists argue time’s punchline is cosmological expansion: as space stretches, time’s ticking rate effectively couples to gravity.
