Why is it constant regardless of how fast the observer or the source was moving.. can anyone explain it to me or give me a good site that explains it?
Thanks in advance
Thanks in advance
Does it seem to you that the speed of light should be constant in some sense--just not independently of the speed of the observer or the source? If so, can you describe what does make sense to you so we can take you from where you are to where you need to be?Abidal Sala said:Why is it constant regardless of how fast the observer or the source was moving.. can anyone explain it to me or give me a good site that explains it?

The speed of light is considered a constant because it has been measured to be the same in all inertial frames of reference. This means that no matter how fast an observer is moving, they will measure the speed of light to be the same, approximately 299,792,458 meters per second.
The constant speed of light was first discovered by the famous scientist, Albert Einstein, in his theory of special relativity. Since then, numerous experiments and observations have confirmed this constant speed, including the famous Michelson-Morley experiment and the observation of cosmic microwave background radiation.
According to Einstein's theory of special relativity, the speed of light is the fastest speed possible because it is the only speed that remains constant for all observers, regardless of their relative motion. This is known as the principle of relativity.
Based on current scientific understanding, the speed of light cannot change. It is considered a fundamental constant of the universe and has been consistently measured as the same value for over a century. Any change in the speed of light would require a major overhaul of our understanding of physics.
The speed of light is often denoted as "c" because it stands for "celeritas," the Latin word for speed. This notation was first used by the famous physicist, Albert Einstein, and has been widely adopted in the scientific community.
