Rather than get into the weeds with this, I present you a gif that represents "nothing." Nothing on camera is a bit different than the concept of nothing. After all, you can actually see that nothing is displayed on the screen after the camera moves. But of course, something is there. It's just a dark room, and I'm pointing the camera at the floor.
Here are a few tweets about #nothing:
