The Plexus -

The Plexus is our universe and all the parallel universes in our multiverse. It includes all other multiverses and everything all the way to the transfinite. The Plexus is the ultimate infrastructure of reality – not just the reality of our own experience, but all the layers of reality that must forever lie beyond our direct awareness. This is not a New-Age website, and if that’s what you’re looking for, then please accept my apologies and feel free to move on. My website is grounded in mathematics and physics and, although it might be hard work, I hope that, by the time you get to the astounding conclusions, you will feel that your efforts have been well rewarded.

I am going to take you on a journey to explain the Plexus, first described in 2016 in a paper in the arXiv electronic repository of scientific papers run by Cornell University [1]. I shall use lots of pictures and diagrams to liven up the dry, minimalist language in which that paper is written, and I hope that this may help to make the significance of some of its statements a little clearer. There isn’t any mathematics or science here that you wouldn’t get in high school. (If you are a physicist and familiar with the field, you may want to skip the foothills of the journey and begin your ascent on the steeper slopes to the summit, starting, perhaps, at the page on wave function collapse [8].)

The next idea that we need on our journey is that the sequence of two events can differ, depending upon the relative speeds of the observers. This is not an illusion caused by the time it takes light to reach the observers. No, we’re talking about real time – in the same way that, if the Sun explodes now, we won’t see it until eight minutes later. The “now” was when it exploded, not when we saw it later. This idea is described in the page on causality and special relativity [4].

In the Many-Worlds [9] page, we saw how to represent the different possible outcomes of a quantum event using Everett’s Many-Worlds tree structure. You need to use different configurations of branches depending upon which observer's point of view you take. In the Tree Structure of the Many Worlds Interpretation [13], we see that all of these different configurations can be represented using the group of parallel block universes containing all of the outcomes. We also work through the logic of the structure which leads us to a surprising conclusion: the number of universes in any branch of the multiverse contains components of kernels from every branch in the multiverse.

At the top of this website, I referred to “astounding conclusions”. Maybe that was hyperbole borne of supressed excitement for what I still consider as a mind-bending revelation – there is a reality at a higher level than our own, and which is totally inaccessible to us, except for that tiny part which makes up everything that ever was and ever will be in our own vast cosmos. For reasons that you will find in the web page, it is appropriate to call this reality a super-reality: Reality and Super-Reality [21].
