Where Do Space, Time and Gravity Come From?

General relativity and quantum mechanics are the two most successful conceptual breakthroughs of modern physics, but Einstein’s description of gravity as a curvature in space-time doesn’t easily mesh with a universe made up of quantum wavefunctions. Recent work that tries to bring those theories together is revealing some mind-bending truths. In this episode, the physicist and author Sean Carroll talks with host Steven Strogatz about how space and time might be emergent properties of quantum reality, not fundamental parts of it.
