Relativistic energy and matter

  1. Aug 22, 2005 #1
    all speed are relative to the observer, but if we have 2 planets with inteligent beings and for one of them all the objects in the universe seem to move just a bit slower than the other planet, wouldnt it then be less matter and energy in thge universe for those biengs? and with finite amount of matter and galaxies it must exist somewhere where its like that.

    (note this is some fast thoughts that flow through my brain, i didnt think it trough so muchy but i want to hear what u guys say)

    This is hard to imagine unless everything in the universe was moving in the same direction. However why should this difference in observed mass be a problem?
