Question on Space time geometry

  1. Aug 18, 2009 #1
    Hi

    Was just going through this site

    http://casa.colorado.edu/~ajsh/sr/centre.html

    As i was going through i tired drawing the spacetime geometry for two objects approaching each other.

    So we would have both the space time planes intertwining each other.Does this mean that the even before the objects actually collide(assuming they collide) they would see each other colliding? That should be so because the time path for the future event(collision) is ahead of the body itself?

    am i getting confused here?:confused:

    The spacetime of the other body wd be seen to be skewed. You cd draw similar diagrams as there to find the other obsever showing lesser time and because the rel velocity is the same, he concludes that the other one sees length to be longitudinally contracted
