Okay, light travels at approx 186,000 miles per second. At this moment in time to our knowledge, there is no evidence that anything travels faster than light. There might be theories that suggest there may well be something's that do travel faster than light but than remains to be proven.
So, I understand that the speed of light is the same regardless of its source. My understanding is that the light from a torch travels the same speed as the light from a distant star, am I correct ?
My other question concerns acceleration of light. Once light leaves its source does it have an acceleration speed ? If so, is there anything that can slow this acceleration down ?
