Entropy and Universal Decay
Everything naturally moves from "neat" to "messy." A sandcastle eventually turns back into flat sand, but the sand never builds a castle by itself. Time only moves forward because things are spreading out.
It's easier to break things than fix them. This "stretch" of the universe is why "now" feels different than "later."
Entropy (S) is a measure of molecular disorder or "multiplicity." The Second Law (ΔS ≥ 0) dictates the irreversibility of natural processes. This creates the "Arrow of Time," distinguishing the past from the future. Philosophically, it connects to Impermanence in Eastern traditions — the recognition that all structured forms must eventually dissipate into the void.

TASTE: Hot cocoa cooling down until it matches the air around it.
TOUCH: Feeling a sand dune — thousands of rocks broken down into tiny grains.
SIGHT: Watching a drop of food coloring slowly cloud a glass of clear water.
BODY: Feeling your body get tired at the end of a long day.
