In fact, we could replace this with a lump of some material (a sphere with a radius of 10 cm for example) in space. We heat the material up and surround it in a perfectly insulating sphere of material to shield it from us, let's say this sphere is 1 light-year in radius (so that in the time frame of our experiment, the lump of material and insulation cannot interact). If we watch the sphere for 10 minutes, it cools down via radiation and so its entropy decreases. [[User:Richardm|Richardm]] ([[User talk:Richardm|talk]]) 14:24, 19 September 2016 (EDT)
