I often feel think that the three-dimensional space and the one-dimensional time can be viewed as arising due to a basic spinorial structure. I am drawing an analogy with the triplet and singlet states which arise when two spin 1/2 are added. Can we say that space and time basically arise from...

Dear Sir, Thanks for your reply which contains reasonable aspects that do not favour such composite nature for photons

A photon annihilates into an electron and a positron (both having spin 1/2). The reverse process is also a reality. Can the photon therefore be viewed as a composite of an electron and a positron having a total spin 1?

Photons have energy as well as momentum. When they fall on objects, they undergo absorption, transmission, reflection, scattering etc. These processes involve transfer of energy as well as momentum. Photons do not have rest mass. One can interpret their energy as a measure of their relativistic...
