Correlations, Representations and the Emergence of Spacetime

Explore the concept of spacetime emergence and dimensional changes at high energy scales in this lecture by Achim Kempf from the University of Waterloo and Perimeter Institute. Delve into the mathematical description of spacetime emergence and potential dimension changes, focusing on an information-theoretic approach. Examine the proposed mathematical structure with different representations in various regimes, and investigate how the number of spacetime dimensions is determined by the balance between generalized bosonic pull and fermionic push. Learn how this balance depends on the number of bosonic and fermionic species at different mass scales, accounting for dimensional changes with energy and allowing for non-geometric regimes. Gain insights into cutting-edge theories about the nature of spacetime and its fundamental structure at the Planck scale.
