Episode notes

String theory requires subersimity to work, and many people expected that this subersimetry had to be visible at the energy of elegcy. When it was not seeing, definitely, this does not rule out string theory at all, because string theory could be tha. Supersimity could be still there, but somehow at higher energy were we haven't seen it. But nevertheless, a lot of people were expecting it. And i think if it had been observed, i, who am not a stringa would have thought, well, these people had the right intuition about nature after all,. so maybethe people have a point for them. It wouldn't prove tosttey

Quantum mechanics and general relativity are the two great triumphs of twentieth-century theoretical physics. Unfortunately, they don't play well together -- despite years of effort, we currently lack a completely successful quantum theory of gravity, although there are some promising ideas out there. Carlo Rovelli is a pioneer of one of those ideas, loop quantum gravity, as well as the bestselling author of such books as Seven Brief Lessons on Physics and the recent The Order of Time. We talk about how to make progress on this knotty problem, including whether string theory will play a role (Carlo thinks not).

In 1988, he and Abhay Ashtekar and Lee Smolin introduced the idea of loop quantum gravity. He is also the author of the "relational" interpretation of quantum mechanics.
