Antimatter is mass-produced

Physicists say they have mass produced antimatter, a crucial first step towards precision studies of its properties that may help solve one of the greatest mysteries of the Universe.

Antihydrogen has been made before, but only a few atoms at a time.

Now, the Cern particle accelerator in Geneva, Switzerland, has produced more than 50,000.

Antimatter is the mirror image of ordinary matter and both should have been created in equal quantities at the birth of the Universe. That everything around is predominantly ordinary matter is therefore a major puzzle.

Cern is the European Organisation for Nuclear Research.
