How big is a photon ? ( Where a single photon can be detected ? )
It is obvious that your second question has "nowhere" answer. Since the calm mass of a photon is zero and therefor you dont detect a free photon in space (In fact it is a point because of that). Your question like that ask: where a single electron that has observed in space-time? Of course both of them (electron and photon) dont equal together really but indeed, we dont answer to these questions to when dont observe them in nature to form of single. But I think thus.
