Claire Zukowski (Columbia University) “Computational Complexity of the Multiverse”

Seminar Organizer

Abstract: I will discuss a new proposal for multiverse analysis based on computational complexity. By defining a cosmology as a space-time containing a vacuum with specified properties (for example small cosmological constant) together with rules for how time evolution will produce the vacuum, we can associate global time in a multiverse with clock time on a supercomputer which simulates it. I will argue for a principle of “limited computational complexity” governing early universe dynamics as simulated by this supercomputer, which translates to a global measure for regulating the infinities of eternal inflation.
