From Wired, May 18, 2021: So imagine the excitement on April 7, when more than 200 physicists from seven countries convened on a Zoom call for a kind of nonexplosive gender-reveal party. What was to be disclosed was not a baby’s sex but the fate of particle physics.

From Smithsonian Magazine, May 13, 2021: A group of scientists say the phenomenon could indicate dark matter speeding through our world at more than 300 miles a second. Fermilab’s Dan Hooper is quoted in this story about the study of flashes seen in ordinary lightning storms showing evidence of super-dense chunks of dark matter as they zip through our atmosphere.

Three factoid cards, which look similar to playing cards or a baseball card, appear on a background of stars in a night sky (or in outer space) in a cartoon rendering. On each of the cards is a circle adjusted its sunglasses, presumably each a type of neutrino. Underneath these images on the cards are scribbles representing text and a question mark. In the upper left corner, the abbreviations for electron neutrino, a muon neutrino or a tau neutrino appear.

Figuring out which type of neutrino is heaviest, or solving the puzzle of neutrino mass hierarchy, would be a huge leap in our understanding of both neutrinos and the physics that govern our universe. The NoVA experiment or DUNE could help physicists do just that.
