That’ll break a few brains. To elaborate with an example: From the perspective of a photon, it’s “life” is over as soon as it begins. Even though it takes about 8 mins for a photon to travel from the sun to the earth from our perspective, no time at all has passed for it.
(Correct me if I misspoke.)
That is a much better description than what I have heard for the last 30 years: “A photon is a packet of energy”. That made no sense to me back then, and makes no sense to me now and, IMHO, doesn’t quite give a good visualization. It’s a placeholder, and I suppose it is slightly accurate depending on how “packet” is defined.
