The discussion centers on whether a photon has a lifespan or ages, with participants debating the implications of special relativity and time dilation. It is established that photons do not age in a conventional sense, as they travel at the speed of light (c) and do not decay. The conversation also touches on the behavior of clocks moving at relativistic speeds, emphasizing that time dilation affects their ticking rate relative to different frames of reference. The consensus is that while photons do not age, the concept of aging can be discussed in terms of coordinate time.
PREREQUISITESPhysicists, students of relativity, and anyone interested in the fundamental principles of time and light in the context of modern physics.
So... I take it you don't understand that clock rates, in general, are frame dependent?GearsofWar said:All I'm saying is that relativistic time dilation is a physical effect and that moving clocks run slow.
