Four years ago, photographer Stanley Greenberg donned full mining gear—including a borrowed suit a few sizes too big—and trudged through a rocky tunnel coursing under Ontario, Canada. The trek eventually led him more than a mile down to SNOLAB, an astroparticle physics research facility located in the bowels of Vale Creighton Mine. There, he changed into clean room clothing in preparation for his final destination—the SNO detector a contraption originally built to hold 1,000 tons of heavy water used to identify neutrinos produced by fusion reactions in the sun. Equipped with a geodesic sphere spanning about 60 feet in diameter, the detector slumbers in a manmade cavern 6,800 feet within the mine’s trenches.
The exhibit Stanlet Greenberg: Time Machines opened on September 13, 2013 and runs through March 30, 2014 at the MIT Museum. His photographs are also available in his book Time Machines.
