P.J.E. Peebles - How will the next big advance in gravity physics be found? (Zoom)

The last three big ideas in physical science go by the names Maxwell’s equations, Einstein’s field equation, and the Schrödinger equation. Einstein hit on general relativity by close to pure thought, with just a few hints from phenomenology. Maxwell put together results from many developments in the laboratory. Quantum physics grew in an intermediate way: several brilliant ideas driven by anomalies in the phenomena. The next big idea about gravity might be found by a stroke of genius, like Einstein, or grow out of examinations of phenomenology. Gravity figures large in cosmology, and there are curious anomalies in this subject. I’ll mention a few that just possibly hint at something interesting.
