Cosmologists believe that most of today's Universe is filled with a mysterious dark energy, which is driving the cosmic expansion into a phase of acceleration.  However, the physics of dark energy is not yet understood.  Over the last 5 years, Swinburne astronomers have been leading Australian efforts to construct an unprecedented map of the distribution of galaxies, stretching back half the age of the Universe.
The patterns in this map provide new measurements of the properties of dark energy and help discriminate between the various possibilities for its origin.
