Einstein’s theory of general relativity is possibly the most perfect intellectual achievement of modern physics. For almost a century now, physicists have been delving into Einstein’s theory, seeking an understanding of the history of the universe, the origin of time, and the evolution of solar systems, stars, and galaxies. Professor of Astrophysics Pedro Ferreira (University of Oxford) will tell us about the expanding universe, black holes and gravitational waves, and how general relativity has allowed scientists’ imaginations to take flight with new possibilities, revealing a universe that is much stranger than anyone ever expected.
