A team of researchers led by Canadians capture antimatter
A team of researchers led by Canadians managed to trap antihydrogen atoms (the antimatter), for more than 16 minutes during an experiment at the European Centre for Nuclear Research (CERN).
This result is a significant advance over the work done last year and who had helped capture 38 atoms of antihydrogen for more than a tenth of a second.
Antimatter is one of the greatest enigmas of modern science. From 1931 the English physicist Paul Dirac predicted the existence of antimatter, matter “mirror” of what we know, but annihilates on contact with it. In Star Trek, is precisely the contact between matter and antimatter, which “throws” the Federation ship!
Depending on the state of our knowledge, matter and antimatter were created in equal quantities in the moments after the Big Bang, but there remains only the matter.
A study published Sunday in the journal Nature Physics and valid concerns that antihydrogen atoms have been trapped for 1000 seconds. This is a time “long enough to begin to study them”, said Jeffrey Hangst Danes who participated in the experiment called ALPHA.
309 atoms have been present long enough for us to look at them in detail. The discovery, in parallel, to the “repulsive gravity” would explain the continuous expansion of the universe, a phenomenon which previously objected to the theory that gravity tended to gravitate toward each other galaxies.
“Capture antimatter atoms for several minutes, opens a whole new perspective in studying the nature of antimatter”, said Fujiwara, a researcher based at TRIUMF in Vancouver and assistant professor at the University of Calgary.
