Fermilab scientist Kirsty Duffy responds to some of the many wonderful questions viewers have left in the comments, including: Were neutrinos made in the early universe? How do you know you’re seeing neutrinos from your accelerator? And can neutrinos pass through a neutron star? Plus, a guest visit from fellow Fermilab science communicator Don Lincoln.

Dark matter remains one of the unsolved mysteries of modern physics. In this video, Fermilab’s Don Lincoln explains two innovative methods whereby Fermilab scientists look for types of dark matter the broader community largely overlooks.

Throw on your shades: Today on #EvenBananas, we’re looking at particles from the sun — and how trillions of them went missing. Join Fermilab scientist Kirsty Duffy to explore how an experiment using 100,000 gallons of dry cleaning fluid a mile underground led to one of the biggest mysteries in particle physics: the solar neutrino problem.

Grab your bibs — in today’s tasty episode, we’re digging into neutrino flavors. Join Fermilab scientist Kirsty Duffy and archivist Valerie Higgins to meet the three flavors of neutrinos and learn how to catch a neutrino with a DONUT.

The Dark Energy Survey tackles big questions about our universe: What is it made of? How is matter distributed? How has the universe evolved? And what roles do dark matter and dark energy play? To address these puzzles, the experiment uses a powerful 570-megapixel camera to photograph galaxies close to home and billions of light years away. The analysis of the first three years of data resulted in the largest maps ever made showing the distribution and shapes of galaxies in our universe — and provided a fantastic test for scientist’s best predictions.

The Muon g-2 experiment announced one of the most tantalizing physics measurements in over a decade. The measurement might tell us that our theoretical calculation is missing some new physical phenomena. Or, a new theoretical prediction points to the possibility that measurement and prediction basically agree. In this exciting video, Fermilab’s Don Lincoln shares an insider’s perspective.

Have you ever wondered how big a particle is — or how scientists even measure something that tiny? Fermilab scientist Kirsty Duffy will answer a deceptively simple question with the help of some sports equipment: How big is a neutrino? Come for the neutrino knowledge — and stay for the outtakes.

In this graphic but family-friendly 40-minute talk, Clifford Johnson, a professor at the University of Southern California, discusses the process of turning complex scientific topics into compelling visual narratives.

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.

Take a virtual tour of the newly-upgraded Ross hoistroom and rock conveyance system at the Sanford Underground Research Facility, hosted by SURF’s Mike Headley, Fermilab’s Joshua Willhite and hoist operator Laurie Adkins-Heydon. Both the hoistroom and the conveyance system are critical to constructing the Long-Baseline Neutrino Facility and Deep Underground Neutrino Experiment a mile below the surface.
