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

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

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 ...

Scientists have spotted the heaviest antimatter nucleus ever detected lurking in a particle accelerator. The antimatter heavyweight, called antihyperhydrogen-4, is made up of an antiproton, two ...

This means our research has empirically ruled out a number of historical theories involving so-called “anti-gravity” suggesting that antimatter would gravitate in exactly the opposite direction as ...

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 ...

For the first time, scientists have observed antimatter particles — the mysterious twins of the visible matter all around us — falling downwards. Physicists an CERN used a 25-centimetre-long ...

Antimatter is identical to matter, except that some of its properties are flipped. For instance, electrons are negatively charged, but their antimatter counterparts, positrons, are positively charged.

If antimatter fell upwards, opposite to gravity, he said, “one of the cornerstones of [Albert Einstein’s theory of] general relativity would be wrong, the equivalence principle ...

NPR's Ari Shapiro talks with Regina Barber and Aaron Scott of Short Wave about elusive antimatter, a brightening night sky and a competition among super-sized grizzly bears: Fat Bear Week.
