Scientists have managed to isolate anti-matter

Scientists of the European Organization for Nuclear Research, CERN were able to isolate and preserve the atoms anti-hydrogen record 16 minutes. This amazing technological discovery promises a better understanding of the mystery of antimatter.

Particles and antiparticles when they collide and cancel each other huge energy release. At the time of the Big Bang about 14 billion years, it is assumed that matter and antimatter existed in the same proportion. To maintain this balance, the universe as known today would not exist.

For unknown reasons, fortunately for us, nature has a mild affinity for the material, so that the rarity of antimatter today, reports AFP. This asymmetry is one of the great mysteries of particle physics.

Experiments with hydrogen atoms, in which little energy is released, could be a key step in solving this mystery.

"Atom anti-hydrogen we can keep the 1000 seconds. This is our time to explore them with such a small number of catch,"said Jeffrey Hangst, a spokesman for Alpha team, which conducted the tests at CERN headquarters in Geneva.

In a study published in the journal Nature Physics, stated that the researchers captured about 300 anti atom.

Scientists have used the CERN particle accelerator to create atoms anti-hydrogen and then they cooled to a temperature close to zero. The aim of the experiment is to use laser and microwave spectroscopy of immobilized particles anti-hydrogen compared with the same particle of hydrogen.

This team last year for the first time managed to capture tens of atoms of antimatter, which was isolated by one-fifth of a second and proved that such a thing is possible in the laboratory. However, it was not enough to perform accurate measurements.

It is expected that measurements anti-hydrogen could bring results later this year.
