The Shape of the Universe: Exploring how the Cosmohedron may reveal its fundamental properties

How is our physical reality structured? Physicists have long imagined that space and time are interwoven into a figurative structure underlying the universe: spacetime. I’ve been doing it. But there may be something more fundamental. Instead of three spatial dimensions of spacetime and one time, the physics of our world could be encoded into a series of strange geometric shapes. And studying them may point to new, space-free paths toward a theory of everything.

“The idea is that spacetime must somehow disappear, it must…
