Speakers: Professor Ed Copeland- The University of Nottingham

Evidence from a number of astronomical observations appear to indicate that over 95% of the energy density making up our Universe is dark, we can not see it but can only infer its existence from observations of things we can see, namely the remaining 5% or so that make up the baryons. The 95% is split up into 25% dark matter which behaves like ordinary matter in that it acts like a pressureless dust, and 70% dark energy, an unusual form of matter which has a negative pressure. This dark energy is causing the Universe to accelerate today. In the talk we will discuss the evidence for dark matter, dark energy and the history of a universe which we believe is some 13.7 Billion years old.
