Scientists at Geneva’s CERN research center using the $2 billion Alpha Magnetic Spectrometer that was delivered to the International Space Station, ISS, two years ago say they think they have finally discovered actual ‘dark matter’.

The research team, headed by Nobel Prize winner Samuel Ting based in Geneva, say they have received preliminary evidence of actual dark matter, the stuff thought to hold the universe together.

Officials say they have observed a high number of positrons, positively charged subatomic particles which are thought to be the decay of dark matter, across a wide swath of the known universe which seems to react to an unknown force, keeping everything from flying apart when gravity is otherwise insufficient.

The AP reports: “This is an 80-year-old detective story and we are getting close to the end,” said University of Chicago physicist Michael Turner, one of the giants in the field of dark matter. “This is a tantalizing clue and further results from AMS could finish the story.”

If found to be true, researchers say this will be the first time the dark matter has ever been directly observed.

Dark matter is estimated to make up as much as 73% of all matter in the universe.
