13/04/2017 Observatory and planetarium Brno www.hvezdarna.cz/program A lecture about the very beginning of our universe presented by one of our most popular science popularizers! The topic was not chosen by chance, because it was exactly 90 years ago that the idea of the Big Bang (but then this name did not exist) appeared for the first time. All this thanks to a Belgian cosmologist and priest named Georges Edouard Lemaître (1894 - 1966). PS You will even laugh :-)
