Ok alot of people smarter than me have probable thought of this and know the flaw in my logic. However working in a guard tower in Iraq... I cant find the flaw only that I know it must be there. here is the question?(adsbygoogle = window.adsbygoogle || []).push({});

I accelatea space ship along the x axis to 0.9 x the speed of light. then I accelarte it allong the y axis to 0.9 x the speed of light. now relitive to the x axis the ship is only travling 0.9 x the speed of light same with relitive to the y axis however along the 45 degree it is travleing aprox 1.2 times the speed of light which is impossible so where is the flaw in my logic... Thanks from a soldier who loves physics
