I find several points of agreement..
I recommended for publication, when sent a copy of Nottale's book for review several years ago. My departed colleague Ray Munroe wrote a paper on how the Scale Relative view helps us make sense of the particle landscape - after I gave him a copy. I also published a paper on Fractal Cosmology, some years back in Chaos, Solitons,& Fractals - dealing with some of the topics you reference. So I am familiar with the territory.
I find parts of this work a bit flaky, but it deserves a much higher rating than it enjoys. If you read my essay, you will see that I explicitly leave room for some of the points you make. I see the most recent void discovery as further evidence that the universe is fractal at all scales. However; I don't think the notion of 'turtles all the way down' is the correct resolution to the enigma in the nanoscale regime.
I have had personal contact with some of the researchers whose work you reference. It is important to properly acknowledge all the work you cite! I got to spend a fair amount of time with the Quantum Gravity folks at GR21, and attend their lectures. So I can flesh out some of the details about CDT, Braneworld scenarios, and other points where you get it almost right but miss the mark. This angle is certainly worthy of further research, but it is not yet a mature theory - only an interesting idea at this point.
There are some subtleties of the Math in higher-dimensional spaces that deserve mention. If you go up to higher dimensions or down to the Planck scale, the factors of non-commutativity and non-associativity must be considered, but even a lot of professional scientists do not treat this correctly. This was the gist of my conversation with Tevian Dray that forms the basis for my essay. I think you will find something to appreciate there.
All the Best,
Jonathan
