Hey, i asked my physics teacher this, but he wasent interested in explaining it to me
Person A is on a boat moving at 10km/h
Person B is on the ground standing still
Person C is walking foward on the boat at 2km/h
Person C in relation to PA is moving at 2km/h
and PC in relation to PB is moving at 12km/h
I understand this concept, but my book said that it does not apply at speeds near the speed of light. So here's my question:
Person A is on a spaceship (pretend, for simplicity reasons) cruizing at the Speed of light.
Person B in standing still on the ground.
PA turns on a flashlight pointing foward.
The light in relation to PA moves foward at the speed of light.
But in relation to PB the light would move at a speed of 2 times the speed of light, right?
However, my teacher told me that in relation to both people the light would be moving at the same rate. Which would mean that the light is traveling at 2 speeds at once (SoL in relation to PA and 2SoL in relation to PB - because the spaceship is cruizing at SoL). This highly confuses me, please explain?
Thanks in Advance
