One of the things about math is that the more problems we look at the more we find a finite set of mathematical objects that can be generated in more than one way, observed in more than one context. These patterns recur in varying and apparently unconnected places.
Here are just a few of the “great ideas” and their specialised manifestations. Every area of maths and science displays them. Patterns that appear in separate domains, systems, phenomena and problems. I say apparently unconnected because, if anything, writing this article has made me realise how what the mystics say is so true: all is one and interconnected.
This list is of course vastly incomplete. After a while of coming up with more and more patterns you just say “right, that’s enough to make the point!” In fact I believe the one true exhaustive list of this kind is infinite. I have no idea for a proof or disproof of that ! Suggestions please.
How many universes can there be ? and what is the ratio of life-producing-universes to (so called) fruitless ones ?
What was the first seed universe like ? What about other universes to ours ?
If ours is the only one then why life ? It seems so unlikely as a one off. Or are there many and living ones evolve among nonliving ones ? If a universe contained no consciousness then would it ever move out of a giant superposed state ? Could there be a multiverse which allocated the saved energy from a nonliving universe to a living one ?
IF THE PURPOSE OF A UNIVERSE AS INITIATED BY A CREATOR IS TO PERFORM A COMPUTATION, THEN HOW IS THE INPUT PROVIDED ? AND HOW THE OUTPUT YIELDED ?
Input is given at commencement through settings of fundamental constants
Output is given in every successive state… each frame of the great movie is one vast output
Thus creator needs “reference dimensions” (the coiled up parts of the 11) to be able to inspect the details of each frame. In order to make use of this output the storage capability of the parent system must be huge but maybe “divine” beings can access that much power.
Yes I do honour Douglas Adams !
Here’s a diagram which shows a possible supercosmology of multiple created universes. Just for fun really but its nice to dream about possibilities.
The second law of thermodynamics states that entropy increases. Will this still hold if the universe starts to contract? Last I heard was that the heat death scenario might be the real one, but what if there was going to be a big crunch ?
I can easily imagine systems becoming more disordered with time, this is common sense, but its nearly impossible for me to imagine the opposite. Am I just prisoner of a mind that evolved in local conditions ? Is it part of some extended physical sensibility that order increasing is perfectly believable ?
If space is contracting then matter is being compressed into a smaller volume so presumably the 2nd law will change and say that order is increasing. One of the issues I have is that if space is contracting (at first) this implies that galaxies are moving together, but you could still imagine life on one planet of one star system in one galaxy where the contraction is not noticeable, and one’s imagination suggests that the second law will still mean disorder is locally increasing.

Physics traditionally studies dead matter. All our analysis of biological systems is a reductionistic one that aims to reduce the extreme complexity of living systems into a form that can be explained using the ordinary laws of physics as they apply to matter and energy. The vitalists thought that life consisted of an indivisible life essence but the whole lesson of reductionism is that once you chop things into sufficiently small parts all you can see is non-living systems.
In modern parlance we describe the appearance of complex behaviours in a system built from its component parts as emergence. Emergent qualities include such things as consciousness. A theory of the living universe would have to explain how complex emergent phenomena arise.
The emergent characteristics of a simple system like a living cell are a consequence of the microscale interactions of the particles composing it. However the richness and complexity of an emergent phenomenon such as the cell would be intractably complex to deduce by simply knowing about the physics of the particles that compose it. And yet at some level the potential for any kind of emergent phenomena must be present within the laws of physics. So we become suspicious that a theory of Everything which could be summarised in a short mathematical form would not indeed contain enough information to explain every kind of phenomenon in the universe – we need a law of emergence.
