12 Thermodynamic Paradoxes That Break the Arrow of Time

Every fundamental equation in physics works backward just as easily as it works forward. Yet in reality, broken glass never reassembles, scrambled eggs never un-mix, and time only marches in one direction. In this deep dive, we explore 12 mind-bending thermodynamic and entropy paradoxes that challenge physical reality, information theory, and the true nature of time.
