A Questioning Thought for the Day

[nachoman]

Assuming that a vehicle could travel at the speed of light simply for the sake of the question, wouldn't having the lighting system inside of a vehicle moving at the speed of light negate the hindrances much like a honey bee flying forwards in the TGV? A honey bee could never achieve speeds relative to the ground of 200 mph. But, put that same honey bee inside the TGV and it could achieve speeds of 214mph in relation to the ground. Thus, to beat this horse just a little more, if you were inside of a vehicle traveling at the speed of light and you flipped on your flashlight fowards, would not that beam of light be twice the speed of light relative to a fixed point?

No, nothing can travel faster than the speed of light. It is against the laws of physics. Hypothetically in a vehicle traveling the speed of light breaks the rules already, so the second question is irrelevant. For example, light leaving a star moving towards us travels...at the speed of light. it isn't the speed of light plus the speed of the star, it is the speed of light (a constant). The way the equations can work out is that time is not constant. In other words, the faster you travel, the slower time travels for you relative to outside observers.
