Dr. Kirsty Duffy talks about how we can see the invisible with detectors. She shares the bizarre story of the first neutrino detector: Project Poltergeist. Plus, MicroBooNE scientist Katrina Miller shows us the materials used to build modern detectors — and what scientists see when a neutrino finally says hello.
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.
Almost everything makes neutrinos — even bananas. But why do bananas produce neutrinos? Are they turning your kitchen into a neutrino factory? Today, we’ll talk about how each of these humble fruits emits more than one million of our favorite particles every day — and some other neutrino sources you might not expect. Join Fermilab scientist Kirsty Duffy to find out!
The Big Bang is the currently accepted theory for the origin of the universe. However, there are some who point to the existence of a very old star, called the Methuselah star, which is said to be even older. If that were true, this would imply that the Big Bang theory is wrong. In this 9-minute video, Fermilab scientist Don Lincoln explains how the Methuselah Star relates to the Big Bang.
Scientists at Fermilab aim to solve the mysteries of dark matter, the mysterious stuff that makes up 25% of our universe. In this recording of a live virtual event, eight scientists explain how their research helps answer questions about dark matter. They give tours of their experiments and show some of the cutting-edge work that takes place at lab. The list of speakers and topics is below. This virtual event was recorded on Oct. 31, 2020, and was part of the worldwide Dark Matter Day, organized by the Interactions collaboration.
Fermilab guest composer David Ibbett composes electrosymphonic music, a fusion of classical and electronic styles. He visited Fermilab in January 2020 to learn more about neutrino research at the lab and started working on his first neutrino-inspired compositions. In this lecture, he presents the results of his work, with a guest appearance by neutrino scientist Bonnie Fleming.
