Playing along with the troll, for a moment, Scepti, if all elements attempt to find their place, if I dig a hole, and I find a tuber while digging, and I put it at the bottom of the hole after digging, deeper than where I found it, why does the tuber not rise to the level I found it at? Why does the natural state of all things seem to be at the bottom, regardless of its weight/ density/ whatever?
I also have a small experiment for you to weigh in on (pun unavoidable). I have two spring scales. One hangs vertically, the other horizontally. Attached to both are identical cables whose weight is known. The cable hangs over a simple pulley with no notable resistance, so that the end of the cable hangs down. In both cases, two object of identical shape and weight are hung from each scale, and show the same weight.
Both weights and scales are inside an evacuation chamber, which is then evacuated. How does this evacuation affect both spring scales, one hanging vertically, one horizontally?
