It's possible to manipulate space-time in such a way that superluminal motion is achievable. For example, the expansion of the universe drives apart galaxies faster than the speed of light ...

and it makes the math much simpler (though still quite complicated). If decoupling takes place, they showed that the inside of a black hole is a mishmash — rather unlike the smooth stretching of space ...

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 ...
