  You Really Can't Tell You're Moving!

  "Just as Galileo had asserted that observing gnats, fish and dripping
  bottles, throwing things and generally jumping around would not help
  you to find out if you were in a room at rest or moving at a steady
  velocity, Einstein added that no kind of observation at all, even
  measuring the speed of light across your room to any accuracy you
  like, would help find out if your room was "really at rest". This
  implies, of course, that the concept of being "at rest" is
  meaningless. If Einstein is right, there is no natural rest-frame in
  the universe. Naturally, there can be no "aether", no thin
  transparent jelly filling space and vibrating with light waves,
  because if there were, it would provide the natural rest frame, and
  affect the speed of light as measured in other moving inertial frames
  as discussed above".
