    May 14, 2007The actual pressure exerted by light is far too small to move these vanes but can be measured with devices such as the Nichols radiometer. Another incorrect theory was that the heat on the dark side was causing the material to outgas, which pushed the radiometer around. This was effectively disproved by both Schuster's and Lebedev's experiments.
