The most consistent way, scientifically, to consider dimensions would be to frame them according to the behavior of the laws of physics. For example, the forces of electromagnetism and gravity permit stable orbits of electrons about atomic nuclei and planets about stars because they obey an inverse square law. This means a doubling of the distance between two masses reduces the gravitational tug they exert upon one another by two squared (or four times); a tripling, by three squared (or nine times): a quadrupling, by four squared (or sixteen times); and so on. To physicists, a three-dimensional spatial manifold is that realm where gravity and electromagnetism obey an inverse square law. In two spatial dimensions gravity and electromagnetism would follow an inverse law. In four spatial dimensions they would obey an inverse cube law; in five spatial dimensions, an inverse fourth-power law; and so on. One of the evidences examined in chapter 3 for the creation of ten space-time dimensions at the cosmic origin moment is the existence, at that time, of inverse eighth-power laws.
