Question: I see that you work with light and stuff! I recently had a few questions about photons-which are what make up light, I think? So, you'd be the perfect person to ask! :D Photons act like both waves and particles, so, a previous question I had was could you make a photon simply behave as a particle and, if you could what type of state would it hold? Also, could photons fill up a room, like gas, so for instance if you had a sealed room with a crack at the bottom and then you released photons through the crack, would they fill the room up, or just the area around the crack? If they wouldn't, would they if they acted like a particle?
