I can't believe nobody has noticed that there's no light in this room. How the hell are you going to see where the walls are, or where your undergarment is falling if you throw it through the air?

One can't be sure if there is air, gravity (or how much), or a singularity sitting right outside the room. We don't know if it is filled with solely oxygen at 100000000000000000000000000000000000000000000000psi.
