I’m sure everybody is aware of the question that people love to ask, i.e. some variation of “what’s the experience of a photon (or someone traveling at $c$, etc)?” This question is always roundly downvoted. Why?
I understand that the question is not strictly about physics because...why exactly? Aren’t there clear ways to interpret this question that are consistent with reality? I feel that we are missing a pedagogical opportunity for a question that is obviously quite popular.
For example, we could talk about limits. What is the experience of an observer in the limit $v \to c$? We could talk about line elements or spacetime diagrams. What’s the length of a light-like line? What does that mean?
I have never answered one of these myself because they’re widely derided and closed. But I’m worried that we’re interpreting this question too rigidly and literally, to the detriment of the curious public.
So why don’t we answer these?
