Astronomers believe the universe contains at least ten times as much mass as
can be seen and accounted for. How they are able to detect this missing
mass and to discover more about it are the subjects of this episode.
Astronomers Vera Rubin and Tony Tyson describe their search for dark matter,
material invisible to us but whose gravity affects the motion of stars and
can alter the light reaching us from distant galaxies. In addition, meet
John Dobson, a self-proclaimed "sidewalk astronomer."
