The speed of light

June 3, 2007 7:03pm CST
In 1887 two American scientists performed a now-famous.The experiment seemed to show that speed of light was independent of motion.In other words,that light always traveled at the same speed:186,000 miles per second.It didn't matter if the source of the light was moving or if the observer was moving

What somebody big is saying is that there is no relative speed for light. If you are walking at a speed of 10kmph in a train that is moving at 60kmph, then if someone outside calls a person in the train and asks your speed he will say it is 10kmph. But to the person on the ground you are travelling at 70kmph. Depends on what the speed is relative to it will change.
