This antimatter and hypernucleic atom consists of an antiproton, two antineutrons, and an antilambda particle. A lambda particle is a hyperon containing one strange quark, while the antilambda is ...

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 ...

Instead, the strange substance must be assembled atom by atom in a process that ... something straight out of science fiction, atoms of antimatter are believed to be the most valuable material ...

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 ...

Experiments at CERN's Antimatter Factory test fundamental principles ... by measuring the frequencies of transitions in the anti-atom using laser light or microwaves. If the results match those ...
