At the beginning of the universe, equal amounts of matter and antimatter collided and there should have been nothing left. Yet, matter won out but why? Fermilab scientist Jessica Esquivel talks with NPR about the mysteries of neutrinos for answers.

From Big Think: Is it true, what goes up must come down? Don Lincoln explores the ALPHA collaboration’s use of CERN’s Antimatter Factory to test if antimatter might experience gravity in a manner opposite of ordinary matter. The conclusion: antimatter does not fall upward.

From Univision, August 11. 2023 (Right click to translate to English): The Muon g-2 results announced last week confirm muons did not behave as predicted by the current theory of physics, the Standard Model. The announcement brings physicists closer to discoveries such as whether there are more types of matter and energy that make up the universe than have been accounted for.

From National Geographic (Poland), Feb. 2, 2023: A group of 150 scientists, including researchers from Fermilab and the University of Chicago, has published one of the most precise measurements of the distribution of matter in the Universe. The analysis is groundbreaking because it used data from two very different telescope surveys and it indicated that something is missing in the current standard model of the universe.

From the Big Think, Nov. 30, 2022: Don Lincoln discusses that while the Universe we see is made solely of matter, there is no explanation for this fundamental asymmetry.
Understanding why the Universe was created with more matter than antimatter is key to understanding why anything exists.

From Science, September 29, 2022: Fermilab’s DUNE and Japan’s Hyper-K experiments are building similar yet different projects that will study neutrino oscillations and search for CP violation in hopes it will lead to answers on how the newborn universe generated more matter than antimatter. Read more on how these two projects are progressing, how they differ and how they might answer more about the elusive neutrino.

From Science News, August 4, 2022: A proposed experiment called Windchime, will try something new: It will search for dark matter using the only force it is guaranteed to feel — gravity. Fermilab physicist Dan Hooper chimes in on what this experiment can mean to the study of dark matter.

From the Finding Genius Podcast, May 4, 2022: The Muon g-2 project led by Fermilab holds the potential to reveal some of the universe’s inner workings. Chris Polly joins the Finding Genius Podcast to explain his work on the Muon g-2 project, how the experiment studies muons and what the results mean relative to the Standard Model of particle physics.

From U Chicago News, April 13, 2021: Scientists at the U.S. Department of Energy’s Fermi National Accelerator Laboratory and the University of Chicago have demonstrated a new technique based on quantum technology that will advance the search for dark matter, which accounts for 85% of all matter in the universe.

From Forbes, April 1, 2021: Don Lincoln explains one of the biggest mysteries of modern physics is the question of why we don’t see as much antimatter in the universe as ordinary matter. Scientists working at the CERN laboratory have announced that they have used lasers to slow the motion of antimatter, resulting in unprecedented capabilities to its properties.
