The dark side of the universe is pervasive. Most of the matter in the universe is dark, most of the energy in the universe is dark. Many searches are underway, on mountain peaks, in deep underground mines, and in space, to discover more about dark matters. Many new telescopes are being constructed on high mountain tops and in space to search for tracers of dark energy.A lecture by Professor Joseph Silk, Gresham Professor of Astronomy 24 October 2018The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/dark-mattersGresham College has been giving free public lectures since 1597.
