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.

Of the four known forces, one of them stands out as different. Gravity is much weaker than the other known forces, and nobody knows why. In this video, Fermilab scientist Don Lincoln describes one possible explanation for the weakness of gravity — the existence of extra dimensions of space.

The ultimate goal of physics is to come up with a theory that describes all of creation – a theory of everything, or TOE. Subatomic Stories was designed to bring the viewer along, one subject at a time, so that they can have an informed understanding of how scientists try to develop a TOE and an appreciation of how we’ll make future progress. In this 13-minute episode, Fermilab scientist Don Lincoln brings it all together and explains where we are and prospects for the future.

Scientists have long called the expanding universe “the Big Bang,” but the term is confusing. Many people think the Big Bang is the name of the moment of the creation of the universe, but it’s really just the expanding phase. In this episode of Subatomic Stories, Fermilab scientist Don Lincoln explains some of the speculative ideas that have been proposed about the actual and literal moment of creation.

The first moments of the universe are still not well understood by modern science. While the theory of the Big Bang covers the big picture, it doesn’t address some detailed questions. In this episode of Subatomic Stories, Fermilab scientist Don Lincoln describes the idea of inflation, which is an addition to the Big Bang. Together, the two theories appear to be another step forward in our understanding of the origins of the cosmos.

Albert Einstein spent the last decades of his life trying to work out a theory that would explain all known phenomena. He failed, but his vision has been pursued by generations of researchers, and there have been many popular science books and articles that imply that such a theory could be right around the corner. In this talk, Fermilab scientist Don Lincoln explains the current status in this timeless quest and give the audience a sense of the prospects for completing Einstein’s dream.

The field of particle physics searches to find the explanation for the universe, focusing on the fundamental building blocks and most basic force that governs them. Our current best theory of the subatomic world is the Standard Model, which invokes quarks and leptons to build the cosmos. In this 13-minute episode of Subatomic Stories, Fermilab scientist Don Lincoln explores the idea that quarks and leptons might not be the final story.
