TOPIC: Beyond the cosmological standard model
LECTURER: Subir Sarkar

The ‘standard’ model of cosmology is founded on the basis that the expansion rate of the universe is accelerating at present — as was inferred from the Hubble diagram of Type Ia supernovae. There exists now a much bigger database of supernovae so we can perform rigorous statistical tests, which show rather surprisingly that the data are consistent with a constant rate of expansion. This motivates discussion of whether dark energy really exists.
