Since 2007 University of Chicago researchers have used the South Pole Telescope in their attempt to help solve the cosmological mystery of dark energy. Little is known about this force, other than that it works against gravity and appears to have sped up the expansion of the universe.
Dark energy, says Michael Turner, director of the Kavli Institute for Cosmological Physics. is "the most profound mystery in all of science." Cracking the problem requires collaborations of original thinkers working beyond the limits of current theories.
