In 1998, everything we thought we knew about the universe was turned on its head with the discovery that the universe is not just expanding, but that this expansion is accelerating. We reconcile the observations and theory by invoking dark energy – its exact nature is unknown, yet it must account for three-quarters of the contents of the universe. Dr Carolin Crawford’s lecture will bring us up to date with this new cosmology and answer questions such as: what are dark matter and dark energy? What is the evidence for their existence? Why do astronomers think they account for the 'missing' 96% of our universe, and what does this mean for the future?
