Researchers pioneer a new way of searching for dark matter
The existence of dark matter is a long-standing puzzle in our universe. Dark matter makes up about a quarter of our universe, yet it does not interact significantly with ordinary matter.
The University of the Witwatersrand, Johannesburg is a multi-campus South African public research university situated in the northern areas of central Johannesburg. It is more commonly known as Wits University. The University has its roots in the mining industry, as do Johannesburg and the Witwatersrand in general. Founded in 1896 as the South African School of Mines in Kimberley, it is the third oldest South African university in continuous operation, after the University of Cape Town (founded in 1829), and Stellenbosch University (founded in 1866).
