Hey all, I guess Einstein has some counter-intuitive, at least naturally, vector addition formula whose result could be that two beams of light traveling towards eachother is basically the same as one beam going towards a stationary object, right? Well..I hope you knwo waht I mean. That the two beams dont just 'add together' to go twice the speed of light if you make one beam stationary. Anyhooo....why? I just don't get why. Where is the logic? Why is it like that?
