Hi Wilhelmus,
Thank you for your comments and I regret that the comments I am giving below may be perceived by you as negative. I'd much rather say complimentary things, but on the other hand, I think it is important to give honest feedback.
First, about the limit. The notion of a limit is a very specific one. It implies a specific quantity with a specific magnitude, and typically also the variation in some quantity as the limit is approached. If you postulate a limit, you have to at least specify what it is a limit of. In my paper, I used axiom I as a mathematical expression to indicate, as specifically as I could, that the fundamental assumption is a limit on spacetime itself (i.e. a quantity that has dimensional units of L^3*T), and that this limit is approached by letting L^3 (*not* L, which is what you seem to be thinking) go to zero. This is very different from postulating that there is a minimum length or minimum time.
There are current modern theories that postulate that there exists a minimum length (such as LQG) but these theories can hide the difficulties that such postulated length or time limits pose by the fact that these limits are not measurable using current technologies. The theoretical difficulties that postulating such length/time limits pose are formidable and that is why such theories are presently regarded as little more than speculation (even though they are called "theories", they are more appropriately *highly speculative* theories, which is a *completely* different animal from our established theories like quantum mechanics and relativity).
To just give you a little bit of a taste, let me briefly review one major problem the assumption of a lower limit on length bring about: According to special relativity, if an object is moving relative to you, you will observe its length to be contracted (i.e. shorter)in its direction of motion as compared to an observer who is at rest relative to that object (assuming properly calibrated measurements). So if that object had (in its direction of motion relative to you) a minimum length, say 10^-48 m, in the frame of an observer at rest, then its length according to you (since its length is contracted) would be even shorter! But if it is a "minimum length" it can't be shorter by definition in any frame (including yours) for then it wouldn't be a minimum length. So either your assumption of a minimum length is wrong, or you have to change special relativity. Because special relativity is one of our best confirmed theories, people are very hesitant to change it, unless you can come up with a changed version that predicts something that you can measure and that is different from what special relativity predicts, do the experiment and show that your changed version gave the correct prediction, not special relativity.
So, you see, there are problems with assuming that there is a minimum length, and physicists who make this assumption typically try to find a way to solve these by proposing modifications to the established theories like special relativity, but this is like messing with the foundation of a house: If you change one thing, it will affect other things, and you will have to change other things, which in turn force you to still change other things and so on. And keep in mind, I have only told you of one problem, there are others. It is therefore not a trivial thing to postulate that there exists a minimum length scale.
Now I can tell you what my opinion is, and bear in mind, this is only a belief, not a scientific argument which I can back up with facts: In my opinion, there is no theoretical lower limit on length or time (i.e. L or T) but there is on spacetime (i.e. L^3T). If the amount of Energy in the universe is finite, there might be a lower practical limit on wavelength, or inverse frequency (because Energy and wavelength or inverse frequency have an inversely proportional relationship). So given, my opinion, I think we do have a substantial difference in our views about a minimum length.
Second, about your paper. I tried to read it, but once again it was difficult for me to understand it. As far as I could tell, you seem to have the notion of quantized world consisting essentially of discrete building blocks given by what you call the "wall of Planck", below which our usual notions of causality, time and distance disappear, something you call "total simultaneity".
This is not an uncommon view, I believe, but it is still regarded as highly speculative. Our two most fundamental theories of nature are General Relativity and Quantum Theory. According to General Relativity, Spacetime is a smooth manifold, which directly contradicts the postulated existence of discrete building blocks greater than zero size. According to quantum theory, while certain quantities are quantized (and are therefore added "blockwise") there is no indication in the theory of fundamental length and time scales. It is true that under certain circumstances, such as a particle in a box with impermeable walls, the theory does predict that there are regions where you will never locate a particle (which would seem like a quantized length scale), but that is a consequence of the setup of that particular situation, not a fundamental result of the theory.
So currently, our established theories do not support your notion. But they don't seem compatible with one another either, yet both describe nature excellently within their own domains. So, it would seem reasonable to assume that the two theories can be made compatible to one another by changing one or both, and some physicists have used this as a way to introduce notions similar to yours.
After reading your paper, I would like to give you, if I may, some constructive suggestions on how to write scientific arguments more effectively. I have found that what I am suggesting below helps me personally both in thinking about a problem and in presenting it two others.
1) Always keep in mind that your number one priority in presenting a scientific argument is to communicate your ideas as clearly as possible. You could have the best idea in the world, but if you communicate it in such a way that no one understands it, then nobody else will know. If you have a friend with similar interests you could ask him/her to read your piece and try to explain back to you what they understood you to say. This will tell you whether you communicated clearly or not.
2) Before you even write up your paper, formulate your argument in a bullet or numbered point format, making sure that each point logically follows from the previous ones. This will help both you and the reader of the paper that is based on the argument constructed in this way, to understand your chain of reasoning more clearly.
3) Avoid, as much as possible, introducing non-standard terms or notation. But sometimes it is unavoidable, in which case you should make absolutely sure that you have the terms defined clearly and explicitly immediately after you introduced them. If you don't do this, it will be a lot less likely that people will seriously consider your argument.
4) Avoid, as much as you can, reference to results of speculative theories of which you may have at best only a superficial understanding to justify results from your own arguments. I get a very strong impression that you take all these speculative theories' results at face value and then try to show that your own notions are consistent with these. Very frankly, I am not sure that you even realize that there is a big difference between established theories like relativity and quantum theory on the one hand, and highly speculative theories like String Theory, Loop Quantum Gravity, and Verlinde's Entropic Force Theory on the other. The reader will likely know that you are not a researcher in one of these fields, so your reliance on the conclusions of these, I think, will diminish, rather than augment your credibility.
I should emphasize, however, that point 4) does not necessarily apply to established theories like Relativity and quantum theory. If you come up with a novel idea that leads to the same result as one of these theories, then generally that is a strength. But you still want to convey that you have a much better than superficial understanding of these theories, and you want to convey this as precisely and clearly as you can. For better or for worse, this usually means that you want to convey this in the form of a mathematical equation that leads to a known result.
Again, I wished I could provide you with more positive feedback, but I hope that you will find my comments helpful in the spirit of constructive criticism.
