Accuracy of Relativity

    Does anyone know what is the most accurate reading of SR's time dilation or space contraction? I.e. has anyone been able to verify the accuracy of SR to 10^-15?

    Not to 10-15, no, (where did you get that figure- just make it up?) but NASA has measured time dilation in space probes agreeing with SR to a relative accuracy of 10-5 which is pretty darn good!

    Yea I was just made 10^-15 up as an example. What about GR? have they found it to an accuracy of better then 10^-5?

    I guess my real question is: How many significant digits have GR and SR been found? i.e. 123.4567 would be 7 significant digits even though it is found to 10^-4.
