Interested in Cosmos, dark matter or dark energy, this talk may be for you.
Recent observations of exploding stars discovered halfway across the Universe reveal an astonishing fact: the expansion of the Universe is speeding up! Apparently, the Universe is dominated by a mysterious dark energy that drives cosmic acceleration. The dark energy may be a modern form of the ‘cosmological constant’ created by Einstein in 1917, but abandoned by him in the 1930s. Robert P. Kirshner, a distinguished astronomer and teacher at Harvard University, explains this astonishing new picture of the universe in a lively, richly illustrated presentation, drawing on his own first-hand account of the discovery.
