The popular claim that a photon does not experience time stems from the fact that the proper time interval along a light-like trajectory is zero. However, this mathematical result does not imply that a photon acts as an observer capable of perceiving the universe or its own existence.
Special relativity defines inertial reference frames only for objects moving at speeds less than the speed of light. Because a photon travels at speed (c), it is impossible to construct an inertial reference frame for it. Consequently, the concept of a photon's 'point of view' is physically invalid.
While observers in different states of motion or gravitational fields measure different time intervals between the same events, time remains a measurable physical quantity. Experiments, such as those involving atomic clocks on aircraft, confirm that time is not a universal flow but depends on movement and gravity.
The assertion that a photon exists eternally or perceives the entire history of the universe is a misinterpretation of relativity. Such claims arise from attempting to apply physical concepts beyond the boundaries of their applicability, confusing mathematical limits with physical reality.
