Yes, that is just a representation for it, however it is not that simple. It does not work for the very big, the very small, the very fast or the very slow. It is just a convenience of Newtonian physics. It works for the vast bulk of what we experience (though it is not entirely accurate) so we just accept it.Originally posted by 4th gen@21 February 2004 - 23:14
Before humans, did 1+1=2?
2 bodies traveling towards each other at 90% of the speed of light, their relative speed is not 180% of the speed of light.
