The Unreasonable Effectiveness of the Klein Bottle | Janna Levin

Discover how the shape of space itself might solve one of physics' deepest puzzles: why matter exists and antimatter doesn't. Janna Levin explores a startling possibility with Brian Greene — that a Klein bottle's geometry, folded into the hidden dimensions of our universe, could explain this cosmic imbalance without forcing scientists to artificially tweak the numbers. What if the universe's fundamental lopsidedness isn't a mystery to patch over, but an elegant consequence of the space we inhabit?
