The American Astronomical Society, Okanagan College, and the Okanagan Science Centre presented Dr. Chris Impey and the Harlow Shapley lecture on Tuesday, March 17, 2009 in the Vernon Kalamalka campus main lecture theatre.
With a musical subtext, this talk explored endings, from the proximate to the distant. Humans are unlikely to be exempt from the extinction that has been the fate of all species on Earth, but we hope that it will not be by our own hand. Eventually, whatever life is found on Earth will be faced with the decay of the biosphere and the death of the Sun. On even longer timescales, the lights will go out in the cosmos as all stars are extinguished. The final curtain comes with the evaporation of black holes and the decay of space-time itself.
