Positronium shouldn't last long enough to be interesting. It's an "atom" assembled from an electron and its antimatter twin — ...

Does antimatter fall down, or does it fall up? For many years, physicists have wondered whether a certain well-known exotic material may experience gravitational repulsion from the Earth. That ...

Antimatter's foundational particles can now reportedly be better-understood thanks to a new study that cools down such particles faster for easier control and better property observance. Researchers ...

Two new studies highlight the enigmatic nature of antimatter, revealing its potential role in both understanding the universe's origins and unlocking the secrets of particle physics. Reading time 3 ...

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has ...

Berkeley Lab physicists and their colleagues in CERN’s ALPHA experiment present the first direct evidence of how atoms of antimatter interact with gravity The atoms that make up ordinary matter fall ...
