A small amount of antimatter took to the road on Tuesday, representing the first time any quantity of the world’s most expensive, volatile and rare substance has been moved. The breakthrough opens the ...

Researchers have trapped a positron and held it at extremely cold temperatures for months, allowing them to measure its quantum properties.

Their discovery could make or break a longstanding theory in physics explaining why our universe looks the way it does ...

Every normal particle of matter has an antimatter counterpart with equal mass but opposite charge. To build their trap, ...

Scientists in Geneva took some antiprotons out for a spin—a very delicate one—in a truck, in a never-tried-before test drive that has been deemed a success. If this so-called antimatter had come into ...

Physicists have successfully transported antimatter by truck for the first time — a milestone that allows them to study the elusive material with unprecedented precision and could eventually help to ...

On August 10, Universe Today asked whether antimatter might come to the rescue of interstellar travel. The question is irresistible. Matter-antimatter annihilation offers an energy density no chemical ...

The explanation behind the universe’s matter-antimatter asymmetry—an apparent violation of a fundamental law of nature known as charge-parity-time (CPT) symmetry—is one of particle physics’ greatest ...

A mile beneath the Black Hills, scientists are building giant detectors to analyse neutrino particles – and possibly find the answer to existence ...

Add Yahoo as a preferred source to see more of our stories on Google. The tank in the center of the lab, lowered beneath ground level, holds the captured positron. After capturing the fast-moving ...
