Information theory Memes

The ultimate physics nerd's bedtime paradox! While most people count sheep, this galaxy brain is contemplating how Quantum Information Theory suggests our universe has zero entropy despite the obvious chaos we observe. For the uninitiated: Quantum Information Theory proposes that unitary transformations (mathematical operations that preserve quantum information) have zero entropy change. If our entire universe is just one big unitary transformation - as some theoretical physicists suggest - then technically its total entropy remains constant at zero. Meanwhile, the second law of thermodynamics says entropy always increases. The cognitive dissonance would keep anyone awake! That peaceful sleeping face? Pure irony. Nothing like a fundamental contradiction in physics to serve as the perfect lullaby.
