4850 Feet Below: The Hunt for Dark Matter
Δημοσιεύτηκε στις 5 Οκτ 2015
Deep
in an abandoned gold mine in rural South Dakota, a team of physicists
are hunting for astrophysical treasure. Their rare and elusive quarry is
dark matter, a theoretical particle which has never been seen or
directly detected. Yet its gravitational effect on distant galaxies
hints at its existence and provides ample evidence to fuel the
experiments and aspirations of scientists at the Sanford Underground
Research Facility. Insulated by 4,850 feet of rock, the researchers have
constructed the world's most sensitive particle detector, known as the
Large Underground Xenon Experiment, or "LUX." Their goal is to use this
complex device to capture an epiphanous event: the interaction between
dark matter and atoms inside a chilled tank of liquid xenon. If they're
successful, the researchers may not only solve some of the biggest
mysteries in astrophysics but affirm their faith in the nature of dark
matter.
