Scientists can trap antimatter atoms and study them! They maybe able to figure out just how this universe came to be.
The achievement is a significant improvement on earlier attempts to trap antihydrogen, which like all antimatter has a tendency to disappear before scientists have time to examine it.
"We went from two-tenths of a second to 1,000 seconds," said American scientist Jeffrey Hangst, a spokesman for the ALPHA research team working at the world's biggest particle physics lab – known by its French acronym CERN – on the Swiss-French border.
The team improved the efficiency of the antimatter trap by cooling antihydrogen atoms down to less than 0.5 degrees above absolute zero. Their research was published online in the journal Nature Physics.
Hangst said extending the lifetime of antihydrogen means scientists can be sure it has enough time to settle so it can be probed and compared with hydrogen atoms. The team will begin firing microwaves and then lasers at trapped antihydrogen later this year.
