Professor Justin Read (University of Surrey) will explain the key evidences for dark matter, and the latest theories for what it is. In particular, he will focus on new results that show that dark matter can be “heated up” and moved around at the centres of tiny “dwarf” galaxies. He’ll demonstrate how this points to dark matter comprising a new particle of nature that remains to be found.
Since its discovery by the Swiss astronomer Fritz Zwicky in the 1930’s, dark matter has continued to capture the public imagination. It raises the velocity of stars and gas in galaxies, bends light around massive galaxy clusters and promotes the growth of structure in the Universe.
Although the primary audience is adults, older children are also welcome to attend.
