    When an object travels near the speed of light from A to B. Does the object's length itself contract in it's frame of reference or does the distance AB contract in it's frame of reference?

    The distance AB contracts in the stationary frame of the object. In the stationary frame of AB the object's length contracts.
    Hence for a photon, the universe has no size (fun right?)

    https://en.wikipedia.org/wiki/Length...ction#Symmetry has a fairly good example.
