Antimatter, an elusive type of matter that's rare in the universe, has now been trapped for more than 16 minutes — an eternity in particle physics.

There is practically no room for antimatter in this or at the interface of any known galaxies or galaxy clusters, severely constraining its possible presence in our Universe. NASA, ESA, ...

Antimatter remains a matter of confusion (sorry, awful pun) for a few reasons. As explained by Gizmodo in 2022: The universe rocked into being 14 billion years ago, with a Big Bang that in theory ...

Antimatter annihilates when it comes into contact with regular matter. That means that it turns into pure energy – not just the sides of the container, but also the molecules in the air.

Antimatter was first discovered in 1928 by physicist Paul Dirac, but it wasn't through any experiment. Instead, he was working to blend theContinue reading "How does the universe make antimatter?" ...

Antimatter is the same as ordinary matter except that it has the opposite electric charge. For instance, an electron, which has a negative charge, has an antimatter partner known as a positron. A ...

CERN physicists have shown that antimatter falls downward due to gravity, just like regular matter, according to a new paper published in the journal Nature. It's not a particularly surprising ...

Antimatter does not “fall up”, but rather responds to the gravitational pull of the Earth in much the same way as normal matter. That is the conclusion of physicists working on the ALPHA-g experiment ...

Antimatter particles detected on the International Space Station (ISS) may be evidence for unknown physics, new research suggests. The particles, antimatter versions of helium nuclei, may have ...

The ALPHA experiment was started in 2013 to study antimatter like never before. It merges antiprotons created in the CERN antimatter factory’s AD and ELENA machines and binds them with positrons ...
