DESCRIPTION:\nOne of the great intellectual achievements of the twentieth 
 century was the theory of quantum mechanics\, according to which observati
 onal results can only be predicted probabilistically rather than with cert
 ainty. Yet\, after decades in which the theory has been successfully used 
 on an everyday basis\, most physicists would agree that we still don't tru
 ly understand what it means. I will talk about the source of this puzzleme
 nt\, and explain why an increasing number of physicists are led to an appa
 rently astonishing conclusion: that the world we experience is constantly 
 branching into different versions\, representing the different possible ou
 tcome of quantum measurements. This could have important consequences for 
 quantum gravity and the emergence of spacetime.\n\nSean Carroll is a theor
 etical physicist at the California Institute of Technology\, and an Extern
 al Professor at the Santa Fe Institute. He is the host of the weekly Minds
 cape podcast. He is the author of several books\, most recently Something 
 Deeply Hidden: Quantum Worlds and the Emergence of Spacetime.
