'Ghost' particle found a mile beneath Antarctica holds key to breakthrough in physics

UK TELEGRAPH reports:

he secrets of the origins of light are set to be unlocked by the discovery of an elusive “ghost” particle a mile beneath Antarctica, scientists have announced.

Astronomers have for the first time identified the source of a high-energy neutrino which shot through a solid ice laboratory at the South Pole last year in a “triumph” that promises to revolutionise understanding of fundamental physics.

Neutrinos are virtually massless, subatomic particles which race across the universe, passing unnoticed through planets and stars.

Despite their abundance - hundreds of billions pass through each human every second - they have so far proved impossible to detect because they interact with matter so rarely....
