No other podcast has this: https://economist.com/TOE Janna Levin — Claire Tow Professor of Physics and Astronomy at Barnard College, founding Director of Sciences at Pioneer Works, and co-host of Quanta's The Joy of Why — is one of those guests who makes you feel the universe is stranger than you feared. Working with Brian Greene, she's exploring whether the shape of hidden dimensions, specifically a Klein bottle, could explain why matter won the war against antimatter after the Big Bang — no fudged parameters required. The geometry does the work. The universe's lopsidedness isn't a mystery to be plugged in; it's a consequence of the space we're sewn into. FOLLOW:

There is no general relativity. There's no spacetime. There's only the quantum threads, the embroidery, the threads out of which you embroidered this illusion of a continuous spacetime.
Curt Jaimungal· Host0:40
[gentle music] Professor Janna Levin, along with co-author Brian Greene, published two papers just last month exploring what it would mean for our universe to be compactified on one of the most bizarre objects in the history of math, a Klein bottle. This is a non-orientable surface with surprising physical properties, potentially explaining the origin of matter, matter that composes you. Is this related to self-referentiality and unprovability? On this channel, I, Curt Jaimungal, interview researchers regarding their theories of reality with rigor and technical depth. Most approaches to CP violation, the matter over antimatter asymmetry, that is the reason we exist rather than annihilate, put in that violation by hand as attuned parameters.
