https://www.scientificamerican.com/article/are-virtual-particles-rea/Quantum fluctuation indicates existence works like a binary system. Particles are either here or not here (like Zero or One), and vary in density, texture, color, etc at more-or-less light speed. Since all things exist in all places dimensionally, we can remove probability clouds and go directly to Planck Length Zero with a sense of confidence.
At the end of the math; it's Magic; because it all connects eventually, even if we can't explain it yet.
