And talking about photons, this is an interesting one, too. I think you'll find this one interesting. Photons, I could have made this a quiz question, too. Can they bounce off each other? But they can't, not directly, the way other particles can. Photons are bosons, they're force carriers, they're carriers of the electromagnetic force. And bosons, they can occupy the same quantum state at the same time, so other particles can't do this, do this or they would collapse into a single point. That's the Pauli Exclusion Principle. And photons occupying the same state don't get in each other's way to stop it. This is repeater station Kilo Kilo 7 November... It is as well light. It interacts with stuff that has electric charge. And this is where light won't interact with itself in a way of bouncing off each other like a photon. A photon, they can't interact directly with another photon because it has no electric charge. They pass right through each other, so they don't bounce off, they pass right through each other. However, there's one way they can collide, but this is still indirectly. Two photons, when they're racing towards each other, can decay into a mass particle, or actually two mass particles, they can turn into an electron and an anti-electron. And these particles interact because they're now mass particles, they also have charge. And an anti-electron can collide with an electron and then will turn back into a photon. So that's the only way a photon can actually collide with one another and interact that way, like just turning into another mass of a particle electron, an anti-electron. And when the anti-electron collides with the oncoming electron, it's inversed back into a photon.
