Key Points
She calculated that collisions involving three different types of subatomic particles would all produce the same wreckage..
Arkani-Hamed therefore suspects that the usual notion of quantum particles moving and interacting in space-time is an approximation of deeper, more abstract concepts, which, if found, could serve as a better language for talking about quantum gravity and the origin of the universe...
Like the amplituhedron, the new geometrical method, known as surfaceology, streamlines quantum physics by sidestepping the traditional approach, which is to track the countless ways particles can move through space-time using Feynman diagrams..
From the space-time perspective, these curves capture events beyond the purview of trace phi cubed theory: colorless particles that the researchers believe could eventually describe gravitons...
Harlow is pursuing another popular research program, known as holography, that seeks to capture space-time in its entirety, including the interiors of black holes, by treating it as a hologram of quantum particles moving around in one lower dimension...
