What's the comment about infrared studies being '''inconclusive''' about? I was under the impression that infrared light was one of the big reasons we knew there weren't any Dyson Spheres nearby. Is the comic referring to a study or something I haven't heard of, or am I overthinking this?

I figured out indirect (diffused) lighting in 1982, in McCutcheon Hall at Purdue University. The central hall had lots of light, but no observable, central light source. I discovered that the light came from hidden fluorescent tubes, diffused against a plastered ceiling. The light we saw, came from overhead, in every direction. The basic outcome is: the more quanta you have, the less precise your measurement can be. OTOH, fewer quanta cast a sharper shadow. | I figured out indirect (diffused) lighting in 1982, in McCutcheon Hall at Purdue University.
