If a body is traveling with the speed of light its origin and destination are one and the same. The question has no point because traveling with the speed of light means you have always been and always will be traveling with the speed of light.
WebIn a constant environment, no. The speed of light is a constant and will always be constant, in that same medium. In the vacuum of space, the speed of light is always 299,792,458m/s. Always. In fact, Einstein showed that everything else moves around light in a different way to make sure that it's constant. tothirstyforwater • 3 yr. ago. WebThe metre is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second. This defines the speed of light in vacuum to be exactly 299,792,458 m/s. This provides a very short answer to the question "Is c constant": Yes, c is constant by definition! However, this is not the end of the matter.
