Did you ever sit under the clear night sky and wonder “does it go on forever?” The size of the universe has long been a question that has puzzled scientists, philosophers and theologians, without a clear answer … until recently. In this 16-minute video, Fermilab scientist Don Lincoln leads you through what modern science can say about the size of the universe.

The Large Hadron Collider is the world’s largest particle accelerator, known mostly for its discovery of the Higgs boson. The LHC will run for another two decades and will collect an enormous amount of data. In this 11-minute video, Fermilab scientist Don Lincoln explains how Fermilab is heavily involved in the upgrades required to make both the accelerator and the CMS detector a physics discovery powerhouse for the foreseeable future.

Scientists are confident that the Big Bang theory accurately describes the life story of the universe over its 14 billion year history, but they have found a discrepancy in two measurements of how fast the universe is expanding. This discrepancy could mean the need to add another twist in the story, or it could disappear with more study. In this 11-minute video, Fermilab scientist Don Lincoln helps us sort it all out.

“Why there is something, rather than nothing?” is a timeless question in both science and philosophy. In this video, Fermilab scientist Don Lincoln explains the theory of leptogenesis, which might be the answer. The international Deep Underground Neutrino Experiment, hosted by Fermilab, will test this idea.

Fermilab scientist Anne Norrick works on the NOvA experiment, looking for hard-to-catch particles called neutrinos. As run coordinator, she helps make sure that NOvA runs smoothly and the particle detectors are in top-top shape. When she isn’t writing code for the experiment or leading tours of the lab’s facilities, she’s having fun playing music, running, reading and traveling.

To celebrate the 150th anniversary of the periodic table, the UN General Assembly and UNESCO have declared 2019 the International Year of the Periodic Table. Fermilab gathered a group of scientists to discuss the importance of the periodic table of the elements in their daily lives, to science, and to humankind.

Aaron Sauers is a bridge between Fermilab and industry. In this 5-minute video, he talks about what means to be Fermilab’s patent and licensing executive. Sauers with the lab’s inventors to find ways that their innovations can help tackle problems and improve our everyday lives. By exploring areas of common interest between the lab and private companies, universities and other labs, he identifies R&D that benefits everyone. For Sauers, finding new uses for lab-developed technologies is the fun puzzle he gets to solve.

The elusive neutrino is the most difficult to detect of the particles of the Standard Model. The story is more complex than that. When a neutrino actually interacts, it is easy to detect. At the same time, they interact only rarely. In this 10-minute video, Fermilab scientist Don Lincoln discusses the trials and tribulations of neutrino hunters.

Meet Harry Ferguson, who has a long history at Fermilab and now runs the Remote Operations Center – West. This room is the central control hub for the lab’s neutrino experiments and sees about 10,000 visitors every year. Ferguson likes the international nature of the lab and the opportunities to stretch and try new things.
