Dark Matter in the Universe
What is dark matter? Where is it? Do we need it? How much is there? Professor Peter Fisher explains the problem of dark matter, the mysterious, invisible stuff that holds galaxies together.
He also describes the current big hunt for dark matter and the unique project he and his collaborators have designed to identify it.
Peter Fisher, Ph.D., Professor of Physics and Division Head, Particle & Nuclear Experimental Physics, Massachusetts Institute of Technology.
