Photons Can't Bumps Into Each Other?

Everything in your body is a constant swarm of particles turning into other particles. The fact that photons don't interact directly with other photons is not really a limitation, because they cantalk other via electrons or vi other charged particles. It's also very strongly a function of the energy. So if you want to see this happenyo, really high energy photons, that's where it's more likely for photons to bounce off each other.
