I was not talking about distributed mass in any complicated mathematical physical way. I meant for all purposes of calculation we consider a plane for example as a point with no physical dimension but still having the same mass of the plane, a point object. We do this to simplify to calculate say the time taken to reach a destination, different parts of the plane should arrive at a destination at different times like the nose reaches first and then the tail of the plane follows. We don't calculate the time taken for every part of the plane and then integrate the result. We consider it as a point object and calculate... that is as in classical physics i'm ot very good with the modren physics so i was not speakig in quarks or photons....
So a point would be the point of concentration of the whole plane mathematically that is.....


A photon cannot again be a point, a point has no dimensions. A photon as a wave has attributes such as its amplitude and wavelength which are measurable. A point is as small as we can get like zero.
