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

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 ...

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 ...

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 ...

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.
