Robert Brandenberger - String cosmology and the breakdown of local effective field theory

QGRAV2021
International Workshop on Quantum Gravity, Higher Derivatives & Nonlocality
8th to 12th March 2021

Abstract: : I will argue that if string theory provides the correct quantum theory of gravity, then local effective field theory will inevitably break down in the early universe. I will discuss approaches to string cosmology which go beyond a local effective field theory description.
