The lecture will be given by Professor Charles L Bennett (John Hopkins University), winner of the Institute’s Isaac Newton Medal for 2017.

As cosmological observations accumulated in the 1980s and 1990s a strange model emerged, a hot big bang universe dominated by nonbaryonic dark matter and an unexpected dark energy driving an accelerated expansion of the universe.

Epic advances in measurement accuracy and precision in the 2000s put this model to an enormously rigorous test, leaving us with a Standard Model of Cosmology: the Lambda-CDM model with six well-specified parameters relating to dark energy and cold dark matter (CDM).

Bennett will discuss how recent measurements – including cosmic microwave background measurements from the WMAP space mission, results of supernovae measurements of the Hubble Constant, measurements of baryon acoustic oscillations, and multiple new measurements of the cosmic microwave background – raise some challenges for this standard model of cosmology. . The lecture will also look forward to some of next experimental steps in observational cosmology.
