If four dimensions are not only possible, but now certain, why not 5 or 10 or 26 dimensions? Indeed, if we jump from Einstein to the present time, that is precisely what has happened in modern physics. All this has taken place because introducing (mathematically) additional dimensions to the physical world unifies the laws, forces and fields of physics, and leads (usually) to simpler and more elegant ways of looking at the universe in which we live.
Discussion of hyperspace rapidly became very complex after Einstein-we must save that for another article. But let us note several things: It is indeed quite likely that the physical, material world we live in has many more than four dimensions.
Ten is a reasonable number to make our physics simple. Discussion of hyperspace still leaves the issue of where God now lives, since he was long ago excluded from the fourth dimension. Unfortunately some modern Christian apologists have implied that God is merely a higher-dimensional being, a cosmic giant who pokes his fingers into our world from time to time, alarming us with visions or miracles which we cannot fully understand. Is God a super being from another dimension?
I dont mean to imply that miracles, visions and UFO intrusions from higher dimensions do not occur! They most certainly occur and I believe they are all real extra-dimensional happenings. The point is: God is not made of matter, He is Spirit and spirit is something fundamentally different from matter.
