Ethan wrote a very interesting post about parallel universes. That got me thinking, and thinking some more. In fact I’ve been thinking about this for nine years. So forgive me as it starts to make some sense to me, and read the following with a pinch of salt.
Time is not the 4th dimension. Time, while a dimensional experience, is purely a product of consciousness. The physical universe incorporates both past and future; the universe, in essence, is a singularity. Within a 10-dimensional orbit of the singularity is the potential for all matter and energy. From a human point of view, all but the narrowest ~3.14 dimensions of space are hidden behind a dimensional horizon. That is why most mass is invisible. We are not so much at the center of the universe as near its edge.
In fact, every galaxy in the observable universe is as near the edge of the universe as we are (although they appear, through telescopes, where they were in aeons past). The true edge of the universe is the “end” of “time” and it is 0-dimensional. If life survives until the end of time, it will have to adapt to less and less dimensional space, and then it will run out. This is unfortunate for the ideal of material gain and progress, but it is fortunate in the sense that time is not what it appears, nor oblivion. Organic life simply has its back turned to God.
At the “beginning” of “time,” the universe is 10-dimensional. The “speed” of light is immediately set. From our point of view, it is the fastest it will ever be, and it will slow down continuously until the end of time. This is why the most distant galaxies are red-shifted, why the universe appears to be expanding ever faster. In fact, the speed of light is slowing down. At the “end” of “time” the speed of light will be zero. There will be no space, no radiation or matter. There will not even be darkness.
If there is a multiverse in the sense of quantum potential, it is possible that only living consciousness collapses it and makes it solid. Life on Earth is a process that only proceeds away from the center of the universe. Thus in our lives time seems to pass, light slows and the universe seems to expand. Our consciousness “tunnels” through the 10-dimensional sphere of potential toward its 0-dimensional limit. But to describe the 0-dimensional edge of the universe is really to restate the singularity. Between the edge and the center, the end and the beginning, is the singularity. In a sense this is the 11th dimension and the ultimate nature of reality.
In response to Ethan’s post, it seems that matter and energy may also be the products of consciousness or awareness. In this case the quantum multiverse is immaterial and thus there is no need to account for duplicated mass or space. There are no concurrent universes because we have no concurrent selves. Consciousness collapses wavefunctions and is not forked by them.
But there is a finite amount of mass in the universe, and a finite number of dimensions in which it can express matter and energy. The question is, are we experiencing or re-experiencing a static universe, or can the universe be recreated with novel manifestations of matter and energy? Does the answer to that question depend on our actions now, on our free will and ingenuity? If time is only a product of consciousness, then only consciousness can recreate the universe, because recreation requires a past.
