An anonymous reader writes: Public radio's WGBH News reports, "Between the announcement this week that scientists have detected primordial gravitation waves and FOX's reboot of Carl Sagan's groundbreaking series, "Cosmos", the Big Bang theory is enjoying its biggest moment since it banged the observable universe into existence 13.8 billion years ago. While the Big Bang is as old as the universe itself, our concept of it is still strikingly new — less than 100 years old. And if you dig into its origins, you come across a curious fact. ... The Big Bang theory was first proposed by a Roman Catholic priest. It wasn't just any priest. It was Monseigneur George Lemaître, a brilliant Belgian who entered the priesthood following his service as an artillery officer in the Belgian army during World War I. He was also an accomplished astronomer and a talented mathematician and physician. After earning his graduate degree in astronomy from the University of Cambridge in England, he came to Boston and spent a year at the Harvard College Observatory before earning his doctorate at MIT. ... At a conference in the 1930s, where Lemaître presented his theory, Einstein reportedly remarked, "This is the most beautiful and satisfactory explanation of creation to which I have ever listened.""
