Question:
Is there a minimum distance between two photons? If so, what is the spacing?

Replies:
Rajan, Particles can be divided into two sets called fermions and bosons. Two identical fermions cannot be in the same place at the same time. Any number of bosons can overlap. The photon is a boson, so there is no minimum distance between them. For two photons to travel together, they would have to be emitted at just the right times and in exactly the same direction. This can happen, but not all the time.
