The de Sitter effect was described by Willem de Sitter in 1913[1][2][3][4] (as well as by Daniel Frost Comstock in 1910[5]) and used to support the special theory of relativity against a competing 1908 emission theory by Walther Ritz that postulated a variable speed of light dependent on the velocity of the emitting object. De Sitter showed that Ritz's theory would have predicted that the orbits of binary stars would appear more eccentric than consistent with experiment and with the laws of mechanics, and would have been inconsistent with astronomical observations. This was confirmed by Kenneth Brecher in 1977 by observing x-ray spectra.[6] For other experiments related to special relativity, see tests of special relativity.
