We'll look at entropy and the second law of thermodynamics, why many fundamental laws still work when time is mathematically reversed, and why shattered glass, spreading heat, ageing bodies, and fading memories never seem to run backwards. Along the way, we'll explore Ludwig Boltzmann's statistical view of entropy, Maxwell's demon, information and Landauer's principle, quantum time-reversal symmetry, black-hole entropy, the low-entropy early Universe, and the mysterious reason our memories always point toward the past. 🌌 Physics can explain remarkably well how the arrow of time behaves once the Universe starts in a special low-entropy state. What it still cannot fully explain is why that state existed in the first place.
