Antimatter was first discovered in 1928 by physicist Paul Dirac, but it wasn’t through any experiment. Instead, he was working to blend the theories of quantum mechanics with special relativity.

There might be a way, though: a new study examines the potential of harnessing antimatter as a fuel source capable of flinging spacecraft across the cosmos faster than any existing technology.

And that could theoretically happen using one of the rarest substances in the universe—antimatter. A new paper from Sawsan Ammar Omira and Abdel Hamid I. Mourad at the United Arab Emirates ...

Writer Chetna Krishna follows CERN’s “coolest” transport, a test of a system to ship stored antimatter across the continent. I reach CERN’s Antimatter Factory at 8 a.m. sharp. I’m here at the ...

Earth is wearing a thin antimatter belt, according to new data that revealed antiprotons trapped high above the planet. Antimatter particles are mirror opposites of normal matter particles.

A truck full of antimatter would make for a seriously epic road trip. And scientists are now one step closer to hauling the substance by motor vehicle. Scientists at the European laboratory CERN ...

Two papers published this week showcase the perplexing origins and potential uses of antimatter, a type of matter that flips the rules governing ordinary matter onto their heads. One paper ...

A new discovery could finally shed light on a persistent cosmological mystery. The heaviest antimatter nucleus ever detected has been observed: antihyperhydrogen-4. Consisting of an antiproton, two ...

An artistic representation of antihyperhydrogen-4 — an antimatter hypernucleus made of an antiproton, two antineutrons, and an antilambda particle — created in a collision of two gold nuclei (left).

Antimatter engines could be humanity's ticket to interstellar travel. When antimatter particles come in contact with regular matter, it produces loads of energy. That energy, if we learn to ...

It’s invisible to the naked eye, will self-destruct if you touch it, and should have caused the destruction of the universe just moments after the Big Bang — enter antimatter, the bad boy of ...
