When Coulomb came up with the charge equation......it was very similar to Newton's gravity equation. Not long after that it was discovered that when you move the charges.......you have to add another term to the equation......a magnetic term to describe the interaction. It has been found that this is true for the gravity equation also. Newton's static equation needs another term too, when the bodies are moving. When we measure gravity on earth......we are so far out of gravitational equilibrium, that we only see the first term. To see this second term we must be in stable orbit....at equilibrium. The second term added to Coulomb's equation causes the charge to spiral or move in a helical fashion. This second term added to Newton's equation causes the mass to spiral in a helical fashion also, but it is ~10^40 times weaker. An object that is in stable orbit does not follow a elliptical path as observed and measured. That is what is so confusing about it. It appears to follow a elliptic, but it doesn't. The orbital path is a helix. As the earth orbits around the sun it follows a one turn helix. This helix carves out a toroid of space with the sun in the center. The center of the earth will always be somewhere on the surface of that toroid. When the earth is on the outside of the helix or toroid, it is in apogee. On the other side of the sun, the earth will be on the inside of the toroid....perigee. But the sun is always in the center of toroid. If you look up orbital parameters and orbital elements, you will see the way that epochs are found. An epoch is the position in orbit at a particular time. I suggest a much easier way. The distance from the sun, along with the angle of inclination, will give us the radius of the toroid. We will call this value Q. The rotation rate of the toroid is 2 pie and the period is one year. We will call this value I. These Q and I values plot the location on the surface of the toroid. Instant epochs. Not bad huh. That seems a lot easier to me. I wonder if NASA could use this. Force interaction is a orthogonal process. It takes 3-D movement to balance. When ever you see a ellipse in nature.......you are looking at a toroid.
