Explore a 32-minute conference talk on quantum gravity and cosmology presented by Eva Silverstein from Stanford University at the 2022 Snowmass Theory Frontier Conference. Delve into recent advances and future opportunities in high-energy physics theory, including particle theory, formal/string theory, cosmological and astro-particle theory, and quantum information science. Gain insights from this recording, which is part of the Particle Physics Community Planning Exercise ("Snowmass") hosted by the Kavli Institute for Theoretical Physics. Learn about the intersection of quantum mechanics and gravity in the context of cosmology, and understand how these concepts contribute to our understanding of the universe's fundamental workings.
