They probably have seen indirect evidence of the presence of dark matter, the mysterious, elusive substance which accounts for most of the matter in
the universe. Many bursts of positrons were detected. These are believed to be released when two bits of dark matter collide.
They found these bursts coming from all parts of the sky. This supports their dark matter origin, as this substance is believed to be distributed
evenly throughout space. The only likely alternative explanation is that the positrons came from nearby pulsars. As these pulsars are mostly confined
to the relatively narrow plane of the galaxy, this seem a less satisfactory explanation.
Definitive evidence that the positrons come from dark matter, or from pulsars, is expected within a few months. As they move their observations up the
energy spectrum, above 350 billion electron volts, two results are possible. Either the total energy declines quickly, which means dark matter has
been found, or it declines much more slowly, indicating pulsars. If the former result is gotten, they will very probably be willing to definitely say
that dark matter has been detected.
