Antimatter is a fascinating kind of matter made up of antiparticles, which have a mass equivalent to that of their normal ...

How is matter different from mass? These and other questions about the deepest levels of physics, answered inside.

While an antimatter engine is very far off, researching it could yield other discoveries as well.

atoms of antihydrogen – a form of antimatter – fall to Earth in the same way as regular matter. Matter is anything that takes up space and has a mass and can be in the form of liquid, solid or gas.

Cosmic rays coming from outside the Solar System bring these particles closer to the Sun, where they experience changes ...

High-powered lasers have transformed the way researchers explore extreme physical phenomena, pushing the boundaries of quantum physics and astrophysics. These lasers, when focused to nearly their ...

Antimatter — the mysterious substance that's the mirror opposite of matter in most ways — falls downward in gravity like everything else in the universe, a team of physicists reported ...

In the Big Bang, matter and antimatter should have been created in equal amounts. But fast forward 13.8 billion years to the present day, and the universe is made almost entirely of matter ...

The Large Hadron Collider (LHC) has once again pushed the boundaries of science by detecting traces of the most massive antimatter nucleus ever observed. This discovery opens a new window into the ...

The findings, which are published in Nature, confirm the capabilities of anti-atom spectroscopy and bring the development of ultra-sensitive tests of antimatter one step closer, and with it a ...

There's a significant imbalance between matter and antimatter in our universe, but a strange particle called "the Majoron" could finally explain it, an audacious new study suggests. When you ...
