The story of modern cosmology arguably begins with the problem of the stability of the Universe that vexed Newton until his death, and vexed Einstein himself more than two centuries later. Dramatic advances in astronomy in the early twentieth century, interpreted in the light of an unsuspected solution to General Relativity prepared the way for a revolution in our understanding of the Universe and its origin; enter the charming figure of L'Abbe Georges Lemaitre. But we were not to recover our equilibrium; encountering the dark sector of the Universe in the second half of the century leaves us finally with the equally unsettling problem about the future of our Universe. Fourteen billion years and a century of discovery breathlessly compressed into an hour.
