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.

Join Fermilab scientist Kirsty Duffy in this 5-minute video as we explore the tiniest, most fundamental particles in our universe. We are kicking off this series with a mystery. Follow along and try to solve it!

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.

There are many ideas rattling around the theoretical physics community that sound outlandish, and one stands out — the idea that our universe is actually a hologram. In this 12-minute episode of Subatomic Stories, Fermilab scientist Don Lincoln sketches the theory of the holographic universe.

One of the great unanswered questions of science is why the laws of the universe seem so carefully tuned to allow for the existence of stars, galaxies, even humans. Scientists, philosophers and theologians have long mulled over this mystery. In this 15-minute episode of Subatomic Stories, Fermilab scientist Don Lincoln talks about the multiverse, which is a highly speculative possible answer to the question.

The principle of supersymmetry has long been one that scientists thought might be the next big discovery in science. In this episode of Subatomic Stories, Fermilab scientist Don Lincoln describes what supersymmetry is and what problems it was intended to solve.

“What is the practical application of your research?” This question is frequently asked of particle physicists. In this talk, Fermilab scientist Jennifer Raaf presents a few practical medical applications that have been enabled by fundamental scientific research undertaken by Fermilab employees. In particular, the talk focuses on a novel ventilator called the Mechanical Ventilator Milano, which was developed for the treatment of COVID-19 patients.
