A team of researchers from the University of California, Riverside (UCR) say they are close to determining whether or not anti-matter exerts a sort of "anti-gravity" in much the same what that ordinary matter exerts regular gravity. In an article published Friday, BBC News reports that, while it is well known that normal matter attracts all other matter in the universe, scientists currently do not know if anti-matter would attract other matter, or repel it. A trio of UCR experts may...

UC Riverside physicists have launched a lab experiment to find out the answer Does antimatter behave differently in gravity than matter? Physicists at the University of California, Riverside have set out to determine the answer. Should they find it, it could explain why the universe seems to have no antimatter and why it is expanding at an ever increasing rate. In the lab, the researchers took the first step towards measuring the free fall of "positronium" — a bound state between...

Researchers isolate collection of "pure" or spin polarized positronium atoms for the first time Positronium is a short-lived system in which an electron and its anti-particle are bound together. In 2007, physicists at the University of California, Riverside created molecular positronium, a brand-new substance, in the laboratory. Now they have succeeded in isolating for the first time a sample of spin polarized positronium atoms. Study results appear this week in the journal Physical Review...

RIVERSIDE, Calif. -- What happens when two atoms, each made up of an electron and its antimatter counterpart, called the positron, collide with each other? UC Riverside physicists are able to see for the first time in the laboratory that these atoms, which are called positronium atoms and are unstable by nature, become even more unstable after the collision. The positronium atoms are seen to destroy one another, turning into gamma radiation, a powerful type of electromagnetic radiation....
