I’ve watched multiple YouTube videos and read a couple things online and now I have a headache. It still doesn’t make sense to me.
If photons have volume, then there can only be a finite number of photons in a given space, right? And once that limit is reached, why can’t I squeeze in one more photon? What is stopping me, the “walls” or “shell” of the photons? What are the walls/shells made of?
Every source I’ve looked at agrees that light is BOTH a wave AND a particle. I can understand why waves don’t have mass, but then what the hell is a “particle”? Every other elementary particle like quarks have mass, right?

One way to shift your thinking is that light is a wave.
Waves can pass through eachother, sit on top of eachother. The reflect, split, interfere and bend.
Waves are the transfer of energy through a medium (for light this is the electro-magnetic field).
When a physicist says light is a wave and a particle what is really meant is light is a specific thing, a “wavicle” that has properties of each. There is no macroscopic, common sense analog to this thing.
