Relativistic velocity limitations

  1. Dec 11, 2009 #1
    A person is in a confined cubicle - say 1m x 1m x 1m. Assuming he is not accelerating, he should not be able to tell if he is moving with respect to any other non-acclerating coordinate system. Are there any limits on his relative speed?

    Ouch, that is cramped. But yes, the limit is v<c.

    Why did we confine the poor man to such a small space? I don't understand what you're getting at with your question.

    What, exactly do you mean by "in a confined cubicle"? What does that have to do with his measuring his motion relative to another system? What instruments does he have to measure with?
