Removing the Container–Michael

Watching a splash of light dancing around my livingroom wall, as I was reading the image from DTS of a containing box being folded up, I wondered where the light on my wall came from.  Without getting up, I worked out that it must be sunlight reflecting off something spinning in the breeze in the back yard.  The sun, 90 million miles away, must be in the container, as well as the spinning thing and my livingroom, I thought.  But the sun wasn’t really a part of any space realm that I was experiencing–any more than the world outside the images appearing on a TV screen are part of my experience.  The image of removing the container didn’t seem very real precisely because my sense of space is itself so dim.  The earlier thought experiment of stretching out a cell was more vivid for me: it immediately threw me into the sense that both before and after the expansion, objects are really just fields of energy.
