The Invisible Universe
We believe that 96% of the mass and energy content of our Universe is invisible. Some is in the form of Dark Matter whose presence we can only detect by its gravitational influence. The majority, called Dark Energy, appears to be ripping our Universe apart.
Ian Morison is an astronomer and astrophysicist who served as the 35th Gresham Professor of Astronomy.
