Dark Matter Day

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.

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.

What keeps galaxies from flying apart? What is the invisible mass that bends light in space? For now, we’re calling it dark matter, and this Oct. 31, laboratories around the world are shining a light on the search for it. Dark Matter Day events include live webcasts with researchers, dark matter scavenger hunts and a Reddit AMA.
