Some Half-Baked Thoughts About de Sitter Space - Leonard Susskind

Explore Leonard Susskind's high-energy theory seminar on de Sitter space, delivered at the Institute for Advanced Study. Delve into the application of the holographic principle to de Sitter space, examining static patches, Busso's rule, and a toy model that acts as a scrambler. Investigate concepts such as anti-de Sitter space, horizons, Boltzmann fluctuations, and ideal de Sitter space. Analyze the Boltzmann formula, quantum projection operators, and transition probabilities in thermal equilibrium. Examine defensive capture, general relativity, thermodynamics, Schrödinger's law, and black holes, including small black holes and their relation to time. Conclude with an exploration of string freezing factors in this comprehensive 89-minute lecture on advanced theoretical physics.
