Antimatter really exists. Elon Musk has called antimatter power "the ticket for interstellar journeys," and physicists like ...

The World's Most Expensive Substance Costs More Than the Global Economy Imagine a material so rare and difficult to produce ...

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 ...

Antimatter is a fascinating kind of matter made up of antiparticles, which have a mass equivalent to that of their normal matter counterparts, yet they exhibit an opposite charge and distinct ...

Experiments in high-energy physics have demonstrated the complete symmetry between particles and antiparticles. A novel theory of the universe that takes this basic symmetry into account is advocated ...

A compact method of detecting neutrinos provides new tests of physics theories and could lead to new reactor-monitoring methods.

Our universe is full of matter, and each and every particle of matter, theoretically, has an antimatter counterpart. These elusive particles have fascinated physicists for decades. And now the ...
