Still going to need some help with this. If there was another ship matching speed and trajectory, who was at the moon at the time the laser was fired, how could the laser directed at the moon travel at .9C, while another laser directed at the other ship travel at C? It shouldn't make a...
How is this reconciled with observations from within the moving ship? Wouldn't they find the recorded time of impact to indicate that light had traveled more slowly than expected?
If a spaceship were to fly at 1/10 the speed of light and project a laser onto a distant moon, would the light cast from the ship reach the moon at 1.1 times the speed of light, relative to a stationary mounted laser fired at the same time/distance?
