Of course you're right - it merely proves that there is a universal attractive force that exists between objects that increases linearly according to their mass and decreases according to the square of their distance from one another.
Nope, it does not prove that either. There is no force between the objects. The only forces in the system are in the torsion and tension of the string.
Now, let me ask you this: How can your version of gravity affect light?
Nothing to do with gravity - silly to even think so, I was referring to some OTHER universal attractive force that exists between objects that increases linearly according to their mass and decreases according to the square of their distance from one another.
Which, again, does not exist.
Nope, not gravity, don't know how that even entered the conversation.
It entered the conversation because you think you know more than you actually do.
Right. Before the other mass was added to the system, there *was* no torsion and tension in the string. After it was, there was torsion and tension in the string.
Fortunately there's no such thing as "Conservation of Mass and Energy", or you would be forced to conclude that the torsion introduced into the system had to do with a measurable attractive force following a precise mathematically predictable relationship to a known mass introduced into the system at the same time.
Which brings to mind the question - Didn't you *do* this test in high school? Mine was a poor high school, but we had a great Physics teacher that actually constructed this test and made us do it ourselves, do the math, et al. I have often been jealous of friends of mine that went to more highly funded high schools, but maybe I'm overestimating how much difference the money would have made.
