271 | Claudia de Rham on Modifying General Relativity
Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and IdeasEinstein's theory of general relativity has been our best understanding of gravity for over a century, withstanding a variety of experimental challenges of ever-increasing precision. But we have to be open to the possibility that general relativity -- even at the classical level, aside from any questions of quantum gravity -- isn't the right theory of gravity. Such speculation is motivated by cosmology, where we have a good model of the universe but one with a number of loose ends. Claudia de Rham has been a leader in exploring how gravity could be modified in cosmologically interesting ways, and we discuss the current state of the art as well as future prospects.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2024/04/01/271-claudia-de-rham-on-modifying-gene
