>You see, whenever an object increases in size linearly, its mass increases exponentially. Polynomially? I see your exponential equation below, but it doesn't make sense (and I have no idea where it came from; what's a "mass differential equation"?) - quadrupling in height should be a volume (and therefore mass) multiplier of 4^3, or 64. That does put us past 7000 pounds, as you say. There are hundreds of other physical reasons such size changes are unworkable, many of them much more fundamental than this. Conservation of mass would seem the obvious place to start..
