Are there antimatter galaxies?

One of the biggest mysteries in astronomy is the question, where did all the antimatter go? Shortly after the Big Bang, there were almost equal amounts of matter and antimatter. I say almost, because there was a tiny bit ...

Explainer: What is antimatter?

Antimatter was one of the most exciting physics discoveries of the 20th century. Picked up by fiction writers such as Dan Brown, many people think of it as an "out there" theoretical idea – unaware that it is actually being ...

Neutral result charges up antimatter research

Scientists of the international ALPHA Collaboration have once again pushed the boundaries of antimatter research with their latest breakthrough studying the properties of antihydrogen. Published today in the prestigious journal ...

Physicists measure force that makes antimatter stick together

Peering at the debris from particle collisions that recreate the conditions of the very early universe, scientists have for the first time measured the force of interaction between pairs of antiprotons. Like the force that ...

Positrons are plentiful in ultra-intense laser blasts

Physicists from Rice University and the University of Texas at Austin have found a new recipe for using intense lasers to create positrons—the antiparticle of electrons—in record numbers and density.

Protons and antiprotons appear to be true mirror images

In a stringent test of a fundamental property of the standard model of particle physics, known as CPT symmetry, researchers from the RIKEN-led BASE collaboration at CERN have made the most precise measurements so far of the ...

Scientists one step closer to mimicking gamma-ray bursts

Using ever more energetic lasers, Lawrence Livermore researchers have produced a record high number of electron-positron pairs, opening exciting opportunities to study extreme astrophysical processes, such as black holes ...
