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.
How do you get the data out of particle detectors? And how do you cleverly and quickly find the data that is the most interesting to explore? In this presentation, Fermilab scientist Wes Ketchum discusses the tricks and techniques that particle physicists use to record rare subatomic interactions in real time and the challenges they encounter.
