The speed of light is a fundamental constant of nature, denoted by the symbol "c" in physics. According to the theory of relativity, specifically special relativity, the speed of light in a vacuum is considered to be the maximum attainable speed in the universe.
In special relativity, as an object with mass approaches the speed of light, its relativistic mass increases, requiring more and more energy to accelerate further. As a result, it becomes impossible for an object with mass to reach or exceed the speed of light.
Light, on the other hand, consists of massless particles called photons. Since photons have no rest mass, they are always moving at the speed of light in a vacuum. From the perspective of a photon, time does not pass. This means that, for a photon, there is no experience of time or temporal progression.
Therefore, it would be incorrect to say that light "time travels" because time itself is not experienced by photons. They exist in a timeless state, always traveling at the speed of light. This is a unique characteristic of light and is a consequence of its masslessness and the principles of special relativity.
