To explain gravity and the expansion of the universe physicists have come up with the theory of Dark Matter. Supposedly it makes up 83% of our universe although not even the finest of instruments can see, touch, smell, taste or hear it. Dark Matter in the arts refers roughly to the same principle. It is the part of the artwork that’s suggested but which is not there for the viewer to see. The three artists in Dark Matter all have their own methods of ‘suggesting’.
