After completion of current project I shall amend my Single Force web pages to accommodate the following rule. The force acting on the centre of any force field is equal to the total force acting on the field surface. This rule allows an explanation of the observed galaxy gravity anomaly along the lines expressed on my Gravity page with the addition that it is now possible to see where the force originates. Those forums dealing with the Casimir force, singularities and renormalisation will observe that the Single force model no longer has any infinities and therefore no need of renormalisation. This also means that the inverse square law as applied in gravity and physics, is not universal but a local phenomonym; As measurement of the galactic gravity force clearly shows it is the relationship between mass, distance and elasticity that determines the nature of the field. The error arises from Newton's assumption that the force at the field centre is zero. As far as I am aware, this assumption has been continued in all subsequent theories. It is the existence of potential force at the zero point that makes creation possible. Sakharov proposed that every possible point in infinity is a zero force point, but if that were so then there is no force to start creation going and there is no vacuum force (or any other force). But once it is accepted that each zero point has a force potential then creation is explainable. It is the Zero point vacuum force potential that makes everything possible. My diagram showing how the bonding field can be used to illustrate atomic fields also shows how the vacuum force builds towards the centre. Simply look at the bonding force as a measurement of the vacuum force.
