Hi. Maybe you can help me understand something. Two identical photons travel parallel in a vacuum. I want the lines of their trajectories to be as close to each other as possible.
1. If each photon could observe the other, what would it detect?
2. Is there a minimum separation necessary to prevent photons from collapsing? Or do they never collapse, regardless of how much separation there is between the two lines?
