antimatter

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.

Results from the ALPHA experiment confirm that matter and antimatter react to gravity in a similar way.

It’s around you, it’s a part of you, and scientists are still trying to figure it out.

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.

In particle physics, “annihilation” is a transformation.

From Tech Start Ups, October 24, 2021: How antimatter can one day power a rocket into space. Former Fermilab physicist Gerald Jackson believes testing an antimatter-based propulsion spacecraft could be a reality by 2050 if the high energy costs to produce antimatter weren’t a factor.

From RECCOM Magazine (Italy), May 17, 2021: Dan Hooper talks about the possible existence of another universe. Physicists believe the Big Bang created equal amounts of matter and antimatter in the early history of the universe – but they can’t explain how antimatter vanished. Perhaps it is not and it resides isolated in some remote regions of our universe.

From New Scientist, April 7, 2021: The strange behavior of a fundamental particle called a muon may hint at the existence of exotic particles and forces beyond the standard model of physics.

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.
