How fast does light have to travel, in a circle (or straight line), for a photon to crash into itself from behind? Could this theoretical process continually multiply photons, creating an infinite light and energy stack?
Update me on the physics and mathematics of this.

Why would it ever do that?

The photon will be in a spot, then be in that same spot some time later. As the speed of the photons cycling increases the time separating the individual instances of the photon (or photons, distinct due to their locations in timespace) decreases. Eventually, the separation time approaches 0. Which is where multiplicatively singular photon overlapping could occur.

You should read about how lasers work.
