Images of Hawking floating in air had already gone viral, when, in 2007 at 65, he boarded a zero-gravity flight test on a specially-fitted Boeing 727. His opinions on more earthbound topics were also frequently sought. When asked by BBC Radio what music he would want if stranded on a desert island, his picks included Brahms, Beethoven, Wagner and “Please Please Me” by the Beatles. His favorite tracks, however, were from Mozart, Puccini and Edith Piaf. He chose crème brulee for his meal.
