[QUOTE="JohnKuthe, post: 8564111, member: 670903"] It's a thought experiment the way Einstein modeled Relativity.And in our thought experiment the spaceship has very powerful headlights. So what do you think happens? Yep. the light moves at the speed of light away from the spaceship, Right? But the spaceship itself is moving at 0.8 times the speed of light, right? But it's Relativity, so the speed of the headlight light is moving AT THE SPEED OF LIGHT (it's a constant, remember?) as measured either by the person IN the spaceship or a fixed observer measuring also the speed of the spaceship at 0.8 tenths the speed of light! How is that possible? ;-) John Kuthe... [/QUOTE]
