::: Yes, the M-M experiment was repeated many times. It had to be done at different times of the year, at different altitudes, with different materials, etc. Eg, maybe the length contraction might have been different for wood and brass.
::: There are physicists who have suggested faster than light particles, but string theory and M theory are Lorentz invariant and useless on the issue. The string theorists would definitely be surprised by anything faster than light. [[User:RSchlafly|RSchlafly]] 02:24, 28 September 2011 (EDT)
:::: Claimed results from a single experiment have been proven wrong before (e.g, the claims of producing [[cold fusion]] in 1989). It makes sense to see if an experiment is replicated before throwing out an extremely well tested theory. It's very suspicious that we haven't seen neutrinos going faster than the speed of light before this. Experimenters are only human beings and could easily have made a mistake or forget to include something in their calculations. The claimed velocity is only a tiny fraction lager than c and might easily be explained by not taking into account some systematic error.
:::: If Mr. Schlafly's other 36 "counterexamples" are so strong then I don't see why he so badly needs the example of an unreplicated experiment whose data is still in the process of being analyzed. (When Einstein was asked about the book '100 Authors Against Einstein' he responded: "If I were wrong, it would only have taken one".) --[[User:MatthewQ|MatthewQ]] 11:27, 28 September 2011 (EDT)
