PhysicsPhysicists have created a 3D shape called the cosmohedron, which can be used to reconstruct the quantum wavefunction of the universe - and potentially do away with the idea of space-time as the underlying fabric of the universe 21 January 2025 Is space-time the fabric of the universe, or is there something deeper?Shutterstock/Mohd. AfuzaWhat is the structure of our physical reality? Physicists have long imagined space and time interweaving into space-time, the metaphorical fabric that underlies the cosmos. But there may be something even more fundamental. Instead of space-times three spatial dimensions and one of time, the physics of our world could be encoded into a set of odd geometrical shapes and studying them may chart a new, space-time-free path towards a theory of everything.The idea is that space-time somehow has to go, that it has to
