To All:
Modest: Thank you for providing a new thread. I realize the subject is a major departure from the purpose of earth science.
Stereologist atal: If you are interested in reviewing the spreadsheets I used to calculate the forces of gravity at descending depths within the earth, I will gladly mail you a CD, at no charge. Just send your snail mail address to my email address that Charlie O will provide, I don't have the number of posts needed to submit an email address.
When I did the calculations I selected a diameter for use in calculating conditions at descending depths. Once a diameter is selected the rest of the earth becomes nothing more than a bunch of gram masses surrounding that diameter. It is a practice used to solve engineering problems and is the exact same practice employed by Newton.
For those of you who are confused by the term "bidirectional" I use it to indicate the vector has two arrowheads one at each end of the line. It is similar to the pull produced by a rubber strand. My horizontal gravitational pull occurs in a 360 degree plane. It is similar to the restorative pull in the skin of a rubber balloon, which in a schematic pulls in both directions in a lateral plane. That is why you cannot feel its effect. But as one progresses into the earth the horizontal pull quickly becomes the dominant force. I think it is the force that holds cloud fragments and planetary bodies together.
