https://community.wolfram.com/groups/-/m/t/1989932
What can be interpreted with Wolfram et al's concepts is the existence of two main overall dimensions: an Updating Event dimension~ and a Relations Processing dimension~~
~ I am using the word dimension here to refer concisely to a set of n-subdimensions but supradimension or omnidimension would be most suitable too!! (Any universe is essentially an "Updating Event" isn't it!)
~~ This would be the complete Quantum Observer that is required for every Updating Event to happen coherently, here speculated to exist in the form of an "exotic extra" dimension (or possibly n-subdimensions) as often mentioned by Dr. Lisa Randall, that perhaps is the state-opposite of the Updating Event dimension, and having the full capacity to process every single updating event and its corresponding relations between distinct elements!

Upon rereading the wonderful long [article][1] it also seems like the two overall dimensions could be described as the Hypergraphee and Hypergrapher dimensions!

https://community.wolfram.com/groups/-/m/t/1983757
I was thinking that Conway's game of Life could be used as a "toy" 2d analog that describes the computational model for people unfamiliar with such models, and it could be far simpler and shorter than the existing material going from hypergraphs to causal graphs to multiway systems.
The point would be the following:
1. The Game of Life is generated by a simple rule
2. Inside the screen - objects like "blinkers" could be identified as clocks, and "gliders" as particles - but there is nothing inside the model or code that expresses those objects explictly
3. a set of "frames" mapping the screen contents at step "t" could be described as the time evolution of a wave equation to an abstract "hilbert space". Each frame could be converted to waves using a superposition of fourier transforms on the frame contents at step "t". This would be an analog to QFT
Now - this model isn't 3d, or multi-way branching - yet it is quite analogous to the concepts expressed in the Wolfram Model - only very simple, and very visual....There is almost no code, and lots of complex behavior.
Is using the 2d Game of Life as a toy analog for the purpose of explanation to others a useful idea?Barry Silverman2020-05-23T21:29:32ZHow to map coordinates in causal and branchial separation?
https://community.wolfram.com/groups/-/m/t/1953636
In the two paper on the relativistic and quantum properties of the Wolfram models it's not specifically explained how the branching section of the multiway causal graph should be mapped, but only its consequences once a specific metric (from a Minkowskian norm) has been added.
The huge problem with this explanation is that there is no single, uniquely acceptable coordinate system for mapping, so changing the coordinates allows you to get whatever you want.
In particular, this is not evident in the paper due to the fact that the examples used have a spatial graph composed of a straight line of points for which a trivial preferential ordering is available.
Is it possible to have an example of how the mapping of coordinates should be done on a causal or branchial graph? In particular, if I have two points of a causal graph, how can I calculate their Minkowskian distance if I have to arbitrarily choose the coordinates of the two points?Federico Pasqua2020-04-24T13:56:22ZWhere would magnetism fit in this model?
https://community.wolfram.com/groups/-/m/t/1960839
I am looking to the "A Class of Models with the Potential to Represent Fundamental Physics" document and I find it lacking of mentions to electromagnetism.
Some sentences I found: "In traditional physics, local gauge invariance already occurs in classical theories (such as electromagnetism), and it is notable that for us it appears to arise from considering multi‐way systems." and "electric/gauge charges: counts of local hyperedge configurations". Later on there is some discussion on the size of the electron.
As seen that the model can explain mass, momentum, and gravity in a relatively nice way, I wonder if electromagnetism would also have a similar explanation. More specifically, could Lorentz force and Maxwell's equations emerge somehow? Or are they expected to be tied to specific rules.Cristóbal Camarero2020-05-01T10:02:25ZIs it possible to find rules by some searching methods or AI methods?
https://community.wolfram.com/groups/-/m/t/1987231
I'm not familiar with physics, especially fundmental physics. But this theory is really attractive to me, so please let me make some discussion on this topic.
###So is it possible to use genetic algorithm or even AI algorithms, such as gradient descent or even GAN, to somehow 'fit' this true universe?
To achieve this, we may need some evaluation functions which may evaluate the simulated graph, that is generated by a given method.
For example, we generate a universe *U* by a given rule set *S*. And we already have some evaluate functions F1 ~ Fn, which in ture universe *R*, we know F1(R) = H1 ... Fn(R) = Hn.
So we can tell how much this generated universe *U* is real by calculating Fi(U) and compare the real world results to Hi.
Is it possible?ji fan2020-05-27T15:04:56Z
