The Many Hidden Worlds of Quantum Mechanics — Season 1, Episode 19: The Challenge of Quantum Gravity
Documentary • 30 min • 1 season, 24 episodes • ★ 10.0/10
Episode synopsis
Quantum theory accounts for a remarkable array of particles and forces-but not gravity. Learn why constructing a successful theory of quantum gravity has vexed physicists for nearly a century. Professor Carroll lays the groundwork for discussing the Many-Worlds perspective on gravity by focusing on two popular alternative theories: string theory and loop quantum gravity.
About The Many Hidden Worlds of Quantum Mechanics
One universe is not enough. Learn about the Many-Worlds Interpretation of quantum mechanics in this exciting course taught by a renowned expert, Sean Carroll.
