The clip comes from The Time Machine, the 1960 MGM film directed by George Pal and adapted from H. G. Wells' 1895 novella. Its time travel sequence, showing the inventor watching the world change around him as he moves forward, became one of cinema's most imitated depictions of travelling through time. The rushing, otherworldly audio from that journey has since been reused and referenced online as a shorthand transition sound, letting editors signal a jump to the past or future without showing a machine or explaining the science.
