This is a rather odd definition of space, and one that I have never come across. Why would one define space as a collection of photons?

Freeze frame a picture of space, every point of that picture will contain a photon moving in some direction. This mass of photons moves as a whole towards matter.


So, what is a proton/ and electron? Are these particles not "matter"?

A neutron is a proton/electron which is a hydrogen atom. No they are not matter they are a volume of space which is neutral which is nothing. The interaction between space and the nothing produces what we call a neutron, proton/electron, hydrogen atom.
