The formation of the atom requires an orbital condition for the electron. The formation of the solar system requires orbital conditions for planets. It appears that any condition of stability in matter is orbital in nature. In this case we must investigate the energy of orbits. The symbol G represents the universal gravitational constant.
Classical physics takes no account of radiation.
For this reason no contraction forms appear. The question of the missing energy cannot be answered by classical physics. Then we turn our attention to contraction theory. Any equation written to describe the action of matter must be subject to two separate conditions. The equation must be mathematically exact and physically correct.
