I am using the Planck length as a base of non causality.
The latest anaysis of Integral 5ESA gamma-ray observatory) places stringent new limits on the size of quantum "grains", it is replaced from 10^-35m to 10^-48m.
These observations of "tiny twisting effects" that are due to the quantum grains , and have become detectable signals , because of the fact they are being accumulated on the very large distance are indeed important for fundamental physics, and also for the view I propose in my essay.
The fundamental question here is "where is causality emerging", at the Planck length or below ?.
To answer this question is not so easy. Fact : before the Integral observations, it was the Planck length, now it could be the "Integral length" of 10^-48m. In fact for the view that I proposed it is not the exact point on a line that is fundamental, every length is a scale compared to another that makes for us our 4D Universe measurable and so causal to represents an idea in our consciousness.
The grains of space/time can and will be adjusted in their dimensinal scales when scientists are going further into the fundamental questions of reality, the idea of these grains being the limit of the causality and thus the border of Total Simultaneity will be the same.
