Motion and the Warping of Space

  1. May 12, 2010 #1
    I was reading that a stationary observer measuring an object in (very fast) motion would determine the object to be shorter in the direction of travel, compared to the size of that object measured at rest. What actually causes this difference from the perspective of the observer?

    Does the fast moving object appear shorter to the observer because the object is actually traveling a shorter distance because of the warped space the object is traveling through? :confused:

    If a man is travelling in a space ship and it is moving with the speed of relative to c, then several changes will occur.
    For the guy in the ship, the space is appear to be bending towards it or in other words you can say that the distance is shortening for him. this will happen because of the increasement of mass of the ship at the speed relative to c (space-time fibre wraps the ship around it).
    But for you, Daisey(who is watching the ship from her rooftops) the space didn't shortens but space ship itself shortens in the direction of motion.
    the cause of this is simple but hard to accept for the new ones in relativity and for those who still have problems with the constant speed of light in all reference frames.
    yes, because of the constant speed of light i.e. 3,00,000 km/sec.
