a constant velocity whether or not you are traveling toward the source, or away from the source?
Nobody knows. That's why Einstein postulated it rather than proved it.jmnance said:a constant velocity whether or not you are traveling toward the source, or away from the source?
Hot Rod SS said:If I'm not mistaken, someone please correct me if I'm wrong, but if you're going 1000mph west and you fire a bullet at the speed of light towards the east, the bullet travels at the speed of light - 1000mph. I vaguely recall the topic of "if you had a car traveling at the speed of light and you turn on you're headlights, what would happen?" My understanding from that would be the light from the headlights would be 2x the speed of light.
I may be in error and if I am I would enjoy clarification. Just contributing to the discussion to understand it myself.

The constant velocity of light, denoted by the symbol c, is the speed at which light travels in a vacuum. It is approximately 299,792,458 meters per second, or about 186,282 miles per second.
The constant velocity of light was first measured and determined by Danish astronomer Ole Rømer in the 17th century, using observations of the moons of Jupiter. Later, the concept was further developed and confirmed by experiments conducted by scientists such as Albert Michelson and Edward Morley in the 19th century.
The constant velocity of light is important because it is a fundamental constant of nature and plays a crucial role in many scientific theories and equations, such as Einstein's theory of relativity. It also serves as a universal speed limit, as nothing can travel faster than the speed of light.
The constant velocity of light can be measured using various methods, such as using interferometers, lasers, or by analyzing the properties of electromagnetic radiation. These methods rely on precise measurements of distance, time, and other variables to calculate the speed of light.
According to current scientific understanding, the constant velocity of light is a fundamental constant that does not change. However, there are some theories that propose the possibility of varying speed of light in certain conditions, but these theories are still being researched and debated by scientists.
