Spalding, his <a href=\"https:\/\/www.iwu.edu\/physics\/\">physics<\/a> student Joseph Richards \u201916 and a team of scientists tackled a century-old intuition from Lord Rayleigh regarding the speed of sound. Rayleigh theorized that music being played on an object traveling faster than the speed of sound, a supersonic jet for example, would result in a listener hearing the music playing in reverse. The Spalding team simulated what an observer standing still would see when looking at a superluminal (faster than the speed of light) occurrence. The results of the scientists\u2019 experiment, conducted last summer at Heriot-Watt University in Edinburgh, Scotland, have been published in <a href=\"http:\/\/advances.sciencemag.org\/content\/2\/4\/e1501691\">Science Advances<\/a>.<\/p>\n<p>\u201cThe existence of an absolute limit, the speed of light, is the natural source of the question: what would happen if we cross this limit?\u201d lead author Mattero Clerici told a writer for a post on <a href=\"http:\/\/www.iflscience.com\/physics\/images-goes-backwards-faster-light-experiment\">IFLScience<\/a>. \u201cLight sources, however, may move faster than the speed of light when their speed is not associated with the physical motion of matter.
