A hypothetical question

  1. Mar 13, 2008 #1
    Say you have only one particle, say an electron or proton or quark in the known universe.

    Can it move? Since matter governs space and so forth, without having another particle as a reference point does movement become totally irrelevant or imposible?

    Since there would only be one frame of reference, defining relative motion would be a problem.

    It couldn't move because there wouldn't be anything to apply a force to it.
