And every minute is more nothingness, and more nothingness, and more nothingness...

The amplituhedron is an exotic, flat-faceted geometric object made up of 3 polyhedra that lives in an abstract, mathematical space of many dimensions. Amplituhedra are a new tool in physics, discovered as recently as late 2013, that vastly simplify former methods of calculating how subatomic particles interact, including elementary particles like photons (where light comes from), quarks, gluons, and “ghost” particles.
An amplituhedron’s anchoring points don’t show where particles actually meet in space and time, unlike prior diagrams by Richard Feynman. Instead, the coordinates represent particles’ momenta, spin, and other movements. The form of the amplituhedron suggests the possibility that the nature of the universe can be described with geometry.
Physicists still don’t know all the implications of the discovery of the amplituhedron, but generally agree that the ultimate prize is a theory of quantum gravity, which would explain the emergence of space and time from some deeper substance or structure. This idea would subvert the widely accepted notions of locality and unitarity, which assume that space and time already exist. Amplituhedra suggest that the most basic forces of nature might be governed by a deeper, simpler mathematical structure than what we ever imagined.
