Why is Time a One-Way Street?

Explore the paradox of time's arrow in this thought-provoking lecture by renowned physicist Leonard Susskind. Delve into the fundamental question of why time appears to flow in one direction, despite theoretical physics equations not distinguishing between past and future. Examine the concept of entropy, the role of the Second Law of Thermodynamics, and how these principles relate to the observed asymmetry of time. Investigate the Standard Picture of cosmology, the nature of the universe's expansion, and the formation of cosmic bubbles. Consider the implications of Boltzmann's ideas and the concept of a "stagnant pool" in the context of time's directionality. Gain insights into how modern physicists and cosmologists approach this fascinating problem, bridging the gap between theoretical physics and our everyday experience of time's arrow.
