The Digital Quest for Quantum GravityCould the key to understanding quantum gravity, one of the most sought-after theories in physics, be much more elementary than many physicists believe? Theoretical physicist Renate Loll has developed an elegant theory called Causal Dynamical Triangulations (CDT) that has produced surprising findings while simulating quantum gravity inside a computer. Her research may one day lead to new insights into how the fabric of space-time formed. 00:00 Is string theory and loop quantum gravity theory wrong? 01:40 What is quantum gravity and how do you develop a theory of it? 02:05 Causal Dynamical Triangulations theory (CDT) 03:27 Computer-simulated quantum gravity revealed a 4D universe 04:28 The future of quantum gravity research Read the full article at Quanta Magazine: https://www.quantamagazine.org/renate-loll-blends-universes-to-unlock-quantum-gravity-20230525/ Learn more about Quantum Field Theory: https://www.quantamagazine.org/what-is-quantum-field-theory-and-why-is-it-incomplete-20220810/ Read an explainer of the path integral in Quanta: https://www.quantamagazine.org/how-our-reality-may-be-a-sum-of-all-possible-realities-20230206/ - VISIT our Website: https://www.quantamagazine.org - LIKE us on Facebook: https://www.facebook.com/QuantaNews - FOLLOW us Twitter: https://twitter.com/QuantaMagazine Quanta Magazine is an editorially independent publication supported by the Simons Foundation: https://www.simonsfoundation.org/ #Quantum #Gravity #physics #generalrelativityhttps://www.youtube.com/watch?v=A7NTNkYPr9QCausal dynamical triangulationCausal dynamical triangulation, theorized by Renate Loll, Jan Ambjørn and Jerzy Jurkiewicz, is an approach to quantum gravity that, like loop quantum gravity, is background independent.https://en.wikipedia.org/wiki/Causal_dynamical_triangulation
