Our Chiral Universe

Our Chiral Universe

Larmor Lecture - Professor David Tong

The fundamental laws of physics look different when reflected in a mirror. This is the statement that the laws of physics have a handedness, what physicists call chirality. This is one of the most important facts that we know about the universe, a fact that, remarkably, goes a long way to fixing the mathematical structure of the laws of nature. I will explain how we know about this handedness, why it’s so important, and why there are still several chiral mysteries that remain unsolved.
