here i go man, can't stop..... ever think about what would happen if the earth began to dissolve, literally? I mean 1st the surface would probably begin to liquifey as some alien solvent (invisible and oderless and tasteless of course) eats it away. Some sort of initial equilibrium may form, where a mile thick gelatenous ooze exists all over the planet, buildings, if constructed well, would probably float on or like within it. It would suck, but life could go on. Eventually though, as the reaction proceeds, the whole world would dissolve. The density would decrease and the radius would increase as a new sort of jelloplanet is spawned, the moon would be engulfed by the ooze and, it being totally anhydrous in chemical composition, it would not dissolve. Well, maybe a thin layer of ooze might form due to some unknow reason, don't ask me to speculate on that now, it' too distracting, it's the big picture I'm after here,
