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.

A supernova is one of the most energetic events in the universe since the Big Bang. Entire stars blow up, announcing their death to the cosmos. In this video, Don Lincoln talks about how Fermilab researchers are building a detector that can peer into the core of the supernova as it is exploding. Neutrinos provide a microscope that cannot be duplicated by any other means.

Perhaps the grandest questions of all are those of how the universe came to be, how it has evolved, and how it will end. While modern science does not have all the answers, the scientific community has discovered many facts that allow us to understand much of this story. In this public lecture, presented on Dec. 9, 2022, Don Lincoln explains what we know — and what we don’t know — about these ageless questions.

2022 Fermilab highlights

Scientists and engineers from more than 50 countries collaborate with Fermilab to develop state-of-the-art technologies and solve the mysteries of matter, energy, space and time. Here are highlights of how they advanced science and technology this year.

At Fermilab, technicians are essential to building and managing the experiments. Hear from five technicians at the lab on what it’s like to contribute to pushing the boundaries of scientific research.

A new neutrino detection system, built for the Short Baseline Near Detector, was transported 3 miles across the Fermilab campus on Dec. 1. Moving the system was no easy feat: The transport began at 6 a.m. and lasted more than 10 hours on the 3-mile journey with a maximum speed of 2.5 miles per hour. Enjoy this short video of the entire move in under two minutes!

How fast is gravity?

Gravity is the most familiar of the known forces, but it seems to be eternal and unchanging. However, scientists believe that gravity moves with a specific speed. In this video, Don Lincoln describes a fascinating observation that definitively measures the speed of gravity.

How cold can it get?

Cryogenics is the science of cold. But how cold is cold? In this video, Fermilab scientist Don Lincoln tells us about some of the most amazing achievements in cryogenic science. And there is no truth to the rumor that he sings at the end.

Pound for pound, of all the particles with mass, neutrinos are the fastest, almost traveling at the speed of light … but not quite. So exactly how fast are they? Neutrino physicist Kirsty Duffy and Durham University neutrino theorist Jessica Turner discuss how fast the elusive neutrinos can travel.
