Hello, I am just curious about this physics question.
I understand the light can travel 300,000,000 m/s in vacuum but if air, water, or something else would interact with it light will move slower.
Here are some questions
Using the example when a boat is moving 40 m/s and a ball is shot at 90 degrees upward it would return back to the original spot on the boat because the ball is also moving at 40m/s.
If a car is moving 30 m/s and has it's headlights turned on, assuming nothing else is effecting it wouldn't the light be moving at 300,000,030 m/s?
Another question is if light was shot into a planet that had nothing affecting the light except its gravity will light travel faster than 300,000,000 m/s, if it doesn't then wouldn't that mean that gravity doesn't effect it?
The reason I was perplexed about this question was because I did not understand how come light was being eaten by the black hole, If the speed of light was not affected by the black holes gravity then it would shoot pass it, but if it doesn't wouldn't that mean there is a possibility of causing the speed of light to move faster than 300,000,000 m/s?
