In a first, CERN physicists succeeded in observing matter-antimatter imbalance in baryons, fundamental particles that make up ...

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the ...

Physicists working at the CERN particle physics lab said they detected a slight but significant difference in how particles ...

So physicists have been on the hunt for any sign of difference between matter and antimatter, known in the field as a ...

For instance, there was a chance that antimatter could be repelled by gravity rather than attracted – meaning it would fall ...

Current models of physics dictate there should be as much antimatter in the universe as matter, but there isn't. Work at the ...

Scientists observe CP violation in baryons, a key clue in understanding why matter dominates the universe over antimatter.

Our universe is filled with particles, such as electrons and protons, which make up all the stuff on our planet and beyond: ...

Imagine something so powerful that one gram of it can buy every private island, yacht, and palace in the world—and still ...

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 ...

When matter and antimatter come into contact, they annihilate each other, transforming their entire mass into energy. This process releases an energy density of 9 x 10¹⁶ J/kg.

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 ...
