Since single electrons and other elementary particles have only a probability, not a certainty, of passing or not passing through a slot, or which of two slots to pass through, it has been postulated that possible events happen in different alternative universes, and that these then continue to evolve in parallel from that point on, to different future outcomes.

With so many particles and so many moments of time presenting choices, there would have to be an almost uniamiganibly large number of parallel universes that have bifurcated from some imaginary beginning.

We inhabit a universe which contains (1) life, (2) humanity, and (3) ourselves as individual persons – a triple improbability of immense dimensions at each of the three stages.

Why this MUST be so, in spite of the tremendous odds against it, is “explained” (?) by the Anthropic Principle: if it were not so, we could not now be wondering about it.

We do not exist in the zillions of parallel universes which, in the aggregate, are so overwhelmingly more numerous than ours.

Even so, we mortal creatures occupy only a limited time span in our own privileged universe. At all other times, ALL the parallel universes exist without us.

This does not mean that the other universes are empty and barren. We simply cannot know, by the same Anthropic Principle, what wonders each may harbour. “The world is not only stranger than we think, it is stranger than we CAN think.”

The God who creates them all (I use the present tense because time is only a dimension like length, width and depth) is in turn created by them. Each parallel universe proceeds in its evolution from Alpha towards Omega in the Teilhardian sense. Some succumb to the equivalent of what, in our universe, is the short life-span of advanced technological societies (which tend to self-destruct, collapsing under their own weight), and never get to Omega.

This may be the fate of our universe, but not necessarily. Our own Earth may self-destruct, as many of us expect, but there may be other islands of life in this same universe which might make it through that choke point. We do not really know the average probability of self-destruction of ATSs in our own universe, since we totally lack empirical data. We do not even know for sure if other ATSs exist here.

In any case, whether our own universe reaches Omega or not, enough of the zillions of others do. (We have no idea how many.) Remember, they do not necessarily contain life as we know it, but perhaps some other principle or essence or phenomenon that we cannot imagine or name, but that is also among the zillions of attributes of God.

Enough completed Omegas evolve to constitute the Godhead that creates and sustains the zillion branching universes.

Since the multiple universes are created in bifurcations, the diagram of their origins constitutes a tree diagram. The branches have no contact with each other.

Now what if there are crosslinks? Could this account for unexplained disappearances and appearances in our universe? For miracles, good or bad? But crosslinks are not postulated by the physical theory of electrons with which we started this speculation, and so we should probably abandon that idea. Unless it is something like “tunnelling” of an electron through a forbidden barrier, which is rare, but well-known in physics. The idea of cross-over points between universes is well known in science fiction, if not in science as such
