Next meeting is this Friday at the University of Toronto at Mississauga. The lecture is open to the public.
Topic: The Startling Speedup of the Expansion of the Universe Speaker: Dr Ray Carlberg, Astronomy Department University of Toronto
Starting with some very simple ideas Einstein built up a theory of gravity which dethroned Newton. Applied to the whole universe Einstein's theory predicts that it is either expanding or contracting, which Hubble found to be expanding. The theory also predicts that the matter in the universe should be causing to the rate of expansion to slow. New ideas of the early universe introduced in the 1980's indicated that the expansion could be accelerating, which Einstein had allowed in his equations. In 2011 the Nobel prize for Physics was awarded for the 1998 discovery that the expansion of the universe was accelerating.
