Professor Brian Schmidt

Professor Brian SchmidtIn 2013 Nobel Laureate for physics Professor Brian Schmidt delivered the second Green Oration, The Accelerating Universe.

Leader of the High-Redshift Supernova Search Team, he described the discovery of ‘Dark Energy’ and how astronomers have used observations to trace our universe’s history back more than 13 billion years, leading them to ponder the ultimate fate of the cosmos.

In 1998 two teams traced back the expansion of the universe over billions of years and discovered that it was accelerating, a startling discovery that suggests that more than 70% of the cosmos is contained in a previously unknown form of matter called Dark Energy.
