Microwaves Used In First Time Measurement Of Antimatter Atom

An international team of physicists at CERN (the European Laboratory for Particle Physics) used microwaves to measure and manipulate an atom made of antimatter for the first time ever. While imprecise, the measurement represents an important first step in being able to study antimatter atoms in detail --  a critical part of understanding why the universe is made of matter and not antimatter. "This is the first time that anyone has ever interacted with an antimatter atom," said lead...

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...

Word of the Day
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'karpos', fruit.
