woodwardiocomI haven't yet seen anyone yet ask, "Hey, what's the lower bound of Monday's XKCD?" Since it's a log scale, that means every step it takes downwards is also only half as long, and therefore it can never reach zero. And therefore again, the lower edge of the art is still some small but measurable distance above the Earth's surface.
Naturally, I sprang into action. The scale appears to be about 17 to 18 pixels for every halving/doubling, so calculating downwards from the 100m mark, the bottom edge of the black area with text is at about 5e-4m, or half a millimeter.
