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

The tug of gravity on antimatter conforms with Albert Einstein's general theory of relativity. If the antiparticles had floated upward in the experiment, as some scientists had hypothesized ...

Producing antihydrogen in this way means that AEgIS can also study positronium, an antimatter system in its own right that is being investigated by experiments worldwide. Positronium has a very ...

In a paper published today in Nature, the ALPHA collaboration at CERN’s Antimatter Factory, which includes academics from The University of Manchester, shows that within the precision of their ...

With a project of this size—around 800 miles long, to be precise—other discoveries are also possible. In fact, a recently published study in the Journal of High Energy Physics from the High Energy ...

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 ...

Join six leading experts to find out everything we know about the subatomic universe. Take a deep dive into the building ...

Transportable antimatter trap The BASE-STEP experiment is on track to transport antiprotons to Germany next year. Credit: CERN-PHOTO-202410-259-53 Thirty years ago, physicists from Harvard University ...

The rotating magnetic field lines in the animation represent the invisible influence of the magnetic field on the antihydrogen. The magnetic field does not rotate in the actual experiment.

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 ...

Antimatter can produce more energy than anything else we know of, but it’s very fickle. A new field analysis explains what we need in order to progress with antimatter propulsion. While an ...
