@RolandD89247800@MAstronomers from the point that you shot it at. And the target is aware of the water only after the water reached it, even though it is “old” water. The same thing is with light. (2)
@RolandD89247800@MAstronomers I always thought of it as a water gun. When you shoot the water gun while moving, the water that you shot out does not reach the target instantly, but instead takes some time to reach it, and it does not go with the movement that you are making but is going in a straight line (1)
