Okay, let me solidify something. I have thought on this until I am dizzy.
Is it true that you just can't fake the density of a pure element? That if, for example, you have a 10 gram piece of what is supposed to be gold, pure gold, in a cube shape, could you not secretly adulterate it? Could not a person take a drill, drill a little cylinder in the cube, place other base materials in it to exactly equal the weight, if not the density, of what was removed, seal the top of the little cylinder made when it was drilled with a thin sheet of gold (under a vacuum), and then have it fulfill the correct displacement for pure gold? I must be missing something, something vital...
And finally, one last buoyancy remark, and I'm DONE with that evil subject: When an object is sitting on the BOTTOM of a lake or ocean, and it is firmly sitting there, sunk in the mud, would not the upward buoyancy, at that point, be zero? And finally, the downward force would be greater than the upward one?
Thanking you in advance.
