Ok, I'm cool with intertial frames of reference.
Let's say we observe a photon that originated from the big bang and moves at a constant velocity of exactly c. That's an intertial frame of reference, right? The photon, as far as it is concerned, is motionless, because it is not accelerating. So it does not experience time dilation, rather everything moving relative to it experiences time dilation, at least from its pov.
So how old is the photon, from its pov? How about from our pov? How old does the photon think we are?
So the question begs... exactly how old is the photon? Is the photon right, or are we right, or are we both right?
