Time dilation is a concept in special relativity that states that as an object approaches the speed of light, time appears to slow down for that object relative to an observer at rest. However, it is important to note that time dilation is a phenomenon observed from the perspective of an external observer, not from the perspective of the object itself.
For a photon, which travels at the speed of light, time does not pass at all. This means that, from the photon's perspective, its journey is instantaneous. However, it is crucial to understand that this is not the same as saying the photon "feels" or "experiences" anything, ascribing consciousness or subjective experience to a photon is not appropriate as it is a fundamental particle of light.
From the point of view of an observer, such as ourselves, it appears that a photon always travels at the speed of light and does not experience any time passing. This is a consequence of the theory of relativity and has been verified through experiments. However, it is important to keep in mind that we can only observe the behavior of photons from an external perspective and not from the photon's own frame of reference.
