MATTER and antimatter are not exact mirror images of each other, say
scientists at the Stanford Linear Accelerator Center in California. The result
will help physicists solve the mystery of why our Universe seems to contain more
matter than antimatter.
Physicists believe that after the big bang, matter and antimatter were
created in equal proportions. But today the Universe seems to contain mainly
matter, so most of the antimatter must have disappeared some time before
“normal” matter—the neutrons, protons and electrons we see now—was
formed. For nature to have favoured matter over antimatter in this way, they
