I find a way to go faster than light !

    Ok you can't go as fast as light. How about two rockets going at 75% of the speed of light in opposite direction? then an observer in one rocket will see the other rocket going faster than light.

    not so fast...

    The relative speed of the rockets will only be 0.96 c. Remember, speeds are added (per Special Relativity) like this:
    [tex]w = \frac{u + v}{1+\frac{uv}{c^{2}}}[/tex]
    not like this:
    [tex]w = u + v[/tex]
