Constructing a consistent and computable quantum space-time, Dr. Seth Asante (Universität Jena)

Einstein’s theory of general relativity successfully describes gravitation by providing dynamics for the geometry of space-time continuum. However, at small scales or in extreme conditions, the smooth structure of space-time breaks down and must be replaced by a notion of quantum space-time. In this talk, I will present a framework for constructing a notion of ‘quantum geometry’, whose dynamics determine the properties of a quantum space-time and is expected to be consistent over all scales. I will focus on simple models to illustrate such a construction, highlighting the key principles and challenges involved in building a computable quantum space-time.
