Someone needs to tell WW to fix this lol. These weight data sticks out like a sore thumb in his usually convincing enough writing of maths and physics.It looks like Weirdworld forgot about the square-cube law. He took the scaling factor between a monster and a human for height and applied it to mass, but forgot that that only works if you only increase size on one axis. If these monsters were all extremely skinny, that would be the right mass, but they're not, so they're ridiculously low density.
