We have the good fortune of living in a universe with tacos. But why does the universe have tasty treats, people, stars and all sorts of matter, instead of nothing at all? In this episode of Even Bananas, Fermilab’s Kirsty Duffy and neutrino theorist Pedro Machado explain how understanding neutrinos is crucial to understanding our universe’s evolution. Grab your lunch, and let’s talk about breaking fundamental symmetries.

Don Lincoln video: Is antigravity real

Despite featuring in sci-fi and many UFO reports, Antigravity is an idea that is potentially scientifically reputable, and scientists at CERN are investigating possible connections between antimatter and antigravity. Fermilab’s Dr. Don Lincoln covers both the fact and fiction of this interesting topic.

From Forbes, April 1, 2021: Don Lincoln explains one of the biggest mysteries of modern physics is the question of why we don’t see as much antimatter in the universe as ordinary matter. Scientists working at the CERN laboratory have announced that they have used lasers to slow the motion of antimatter, resulting in unprecedented capabilities to its properties.

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.
