Time and space are frequent topics of discussion for cosmologists ... the tree evaluation problem—as described by Quanta Magazine—“involves repeatedly solving a simpler math problem that turns a pair ...

Curious connections between physics and math suggest to Latham Boyle that space-time may survive the jump to the next theory of reality. A decade after the discovery of the “amplituhedron,” physicists ...
