## [colloquium] Trans-Planckian Censorship, Breakdown of Effective Field Theory and Emergent Cosmology

May 12, 2022, 3:00 PM
1h 20m

### Speaker

Robert Brandenberger (McGill University)

### Description

I will argue that effective point particle field theory will inevitably break down in a rapidly expanding universe. Hence, a non-perturbative formalism is required to understand the very early universe. A new approach based on matrix theory (a proposed non-perturbative definition of string theory( will be discussed, which yields an emergent" cosmology.
