Antimatter and other deep mysteries – Public lecture by Dr. Gerald Gabrielse

Our universe is made of matter. Yet the Big Bang produced essentially equal amounts of matter and antimatter according to our most fundamental understanding of the building blocks of nature. The inability of our fundamental theory to describe this basic feature of our universe is the great frustration of modern physics. In this one-hour lecture, held on Feb. 19, 2021, Dr. Gerald Gabrielse, Northwestern University, gives an introduction to antimatter and matter, explains the theoretical framework that explains particle interactions, and gives examples of attempts to solve the mystery of antimatter.

Dr. Gerald Gabrielse, a member of the National Academy of Science and the American Academy of the Arts and Sciences, is a Trustees Professor at Northwestern University. His vision, techniques and measurements started low-energy antiproton and antihydrogen research at the European laboratory CERN. He has made the most precise measurement of a property of an elementary particle, the electron’s magnet, to test the Standard Model’s most precise prediction. His test of whether the electron charge is spherical is one of the most sensitive tests for physics beyond the Standard Model.
