What is parity and how can it be violated?

A striking asymmetry in the arrangements of galaxies in the sky has been announced. If confirmed, the finding would point to features of the unknown fundamental laws that operated during the Big Bang.

“If this result is real, someone’s going to get a Nobel Prize,” said Marc Kamionkowski, a physicist at Johns Hopkins University who was not involved in the analysis.

Brian Keating and Oliver Philcox discuss the large scale structure of the universe and how enigmatic space tetrahedrons, drawn between galaxies, may map out some key features of the most poorly-understood phases of early big bang cosmology.

Oliver Philcox is a theoretical physicist interested in statistical cosmology. He obtained his Bachelor’s and Master’s degrees in Cambridge’s Institute of Astronomy before spending a year in Harvard’s Center for Astrophysics. He is a Junior Fellow in the Simons Society of Fellows, hosted at Columbia University.
