According to our current understanding of physics, light does not experience time in the same way that we do as observers. From the perspective of a photon (a particle of light), time does not pass. This concept is based on the theory of relativity, specifically the phenomenon known as time dilation.
Time dilation occurs when an object moves at speeds close to the speed of light. As an object's velocity approaches the speed of light, time appears to slow down for that object relative to an observer at rest. For photons, which travel at the speed of light, time effectively stands still.
However, it's important to note that while light itself does not experience time, it still takes a finite amount of time for light to travel from one point to another. This might seem paradoxical, but it arises from the fundamental nature of spacetime and the limitations imposed by the speed of light.
In our understanding of the universe, the speed of light in a vacuum is an intrinsic property of spacetime. It is the maximum speed at which information or causality can propagate. This speed is finite and equal to approximately 299,792,458 meters per second. While light does not experience the passage of time, it still follows the rules of spacetime and takes time to traverse distances.
The reason for the finite speed of light lies in the fundamental structure of our universe and the nature of electromagnetic waves, of which light is one form. Light travels as a disturbance in the electromagnetic field, and this disturbance propagates at the speed of light. The finite speed of light is a fundamental aspect of our physical laws and has been extensively tested and validated through numerous experiments and observations.
