Scientists are pretty sure the universe started with the Big Bang. But the furthest back in time we can explore is 370,000 years after spacetime began. So, how do we measure the Big Bang, and how could our favorite friends — neutrinos — revolutionize our understanding of the early universe? In this video, physicist Kirsty Duffy explores these concepts and discusses the cosmic neutrino background.

Using neutrino experiments at Fermilab as an example, Jorge Morfin explains the path of a large physics experiment from inspiration through the proposal process to approval. The lecture is part II of the virtual lecture series, “How to do big science,” hosted by the Fermilab Arts & Lectures At Home Series.

Neutrinos are powerful tools for better understanding how the universe works and improving our theories, like the famed Standard Model. But what else are neutrinos good for? Neutrino physicist Kirsty Duffy explains some of the (mostly not-so-practical) ways we might use neutrinos.

This two-minute video features the PIP-II project, which is an essential upgrade of Fermilab’s particle accelerator complex. It is the first U.S. particle accelerator project with significant contributions from international partners. PIP-II’s high-intensity proton beams will provide a flexible platform for the long-term future of the Fermilab accelerator complex and the U.S. accelerator-based particle physics program. It enables the scientific program for the international, Fermilab-hosted Deep Underground Neutrino Experiment and Long-Baseline Neutrino Facility.

Two videos of Secretary of Energy Rick Perry’s Jan. 9 Fermilab visit are now available on the Fermilab YouTube channel. This 3-minute video gives an overview of the experimental areas and facilities that Perry toured. A 45-minute video of the Jan. 9 all-hands meeting with Perry is also online.
