New things in Science

Geometry trumps endless math - the Amplituhedron
Locality is the notion that particles can interact only from adjoining positions in space and time. And unitarity holds that the probabilities of all possible outcomes of a quantum mechanical interaction must add up to one. The concepts are the central pillars of quantum field theory in its original form, but in certain situations involving gravity, both break down, suggesting neither is a fundamental aspect of nature.
Gravity is trumping some fondly held beliefs that are seen only from a human point of view. Curiouser and curiouser said Alice
