Physicists reported discovery of a jewel-like geometric object (the amplituhedron) that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality.

The iconic 20th century physicist Richard Feynman invented a method for calculating probabilities of particle interactions using depictions of all the different ways an interaction could occur. Examples of “Feynman diagrams” were included on a 2005 postage stamp honoring Feynman.
