It is often claimed that Relativity is proven by its ability to explain aspects of electromagnetism.  But those aspects do not relate to physical mass, gravity or various frames of reference throughout the universe -- the basic claims of relativity.--[[User:Aschlafly|Andy Schlafly]] 20:59, 21 August 2011 (EDT)

: Lorentz used electromagnetic relativity to predict relativistic mass in 1899, and it was experimentally confirmed a couple of years later. Poincare used E=mc2 for radiation in 1900. So I think that electromagnetic aspects of relativity do relate to physical mass. They also relate to various frames of reference, as electromagnetic experiments were done at different times of the year to test different frames of reference in the Earth's orbit. Gravity and electromagnetism are separate forces, and I guess it is fair to say that relativistic aspects had to be tested separately. [[User:RSchlafly|RSchlafly]] 00:04, 22 August 2011 (EDT)

I'm not sure how good an argument this is. ONE out of a batch of 40 identical standard kilogrammes has diverged in weight from the others. Common sense says that there's something wrong with that one weight, which is after all stored in France. It's not likely that the answer has anything to do with relativity, which if correct would have caused an identical change in mass in all 40. --[[User:JMairs|JMairs]] 21:06, 21 August 2011 (EDT)

: I have a drawer full of socks. I cannot find a match for one of them. Can I blame relativity? [[User:RSchlafly|RSchlafly]] 00:04, 22 August 2011 (EDT)
