A very erroneous description.

Photons are their own anti-particles. Same for all the mediating 
bosons (gravitons, W, Z, gluons).

Well, everything is energy. Photons have energy, and momentum, but 
have no rest mass.

Depends one the energy involved. Can be the creation of massive 
particles. If the photons have different wavelengths then nothing, 
they simply carry on regardless. I think, it's been a few years.
