We survey the idea that the particle/field duality can be promptly visualized using the LAN structure of modern computer networks, as the LAN seems point-like from outside (one point of contact with the internet, one public IP address), but its expansive nature affects its interactions (i.e., signal exchanges) with other LANs. The central premise is thus to consider all elementary particles (including empty space and the constituents of Dark Energy and Dark Matter) as being networks of nodes – termed átmita. In this work, some fundamental properties of átmita and their communication protocol are outlined. Utilizing this protocol, it is shown that placing LANs of átmita on the lattice of space generates defects, which increase the effective distance between points lying on opposite sides of them. It is explicitly shown that the Schwarzschild metric is valid around a spherical mass, as these diffusion-driven space-defects generate an effective curvature. Additionally, placing any LAN system in empty space generates three fully symmetric, mutually non-interacting versions of each particle type, termed X- Y- and Z-bases. Two of them (arbitrarily X and Y), are argued to be Dark Energy (DE), with all particles of Regular Matter (RM) and Dark Matter (DM) belonging to the third base. This would make DE Quintessence-like, but there are no distinct DE particle types to be found, each of the two DE bases has its own copy of all Standard Model and DM particle types. The three bases’ symmetry at the limit of low redshifts leads to ΩDE(t→∞)=0.66¯ and Ωm=0.33¯, in excellent agreement with the values reported by the Dark Energy Survey (Ωm=0.333−0.016+0.015) and by Pantheon+ (Ωm=0.334±0.018). Based on the above fully symmetric model for DE, Z-based particles are suggested to be able to tunnel through a (Z-based) barrier by turning for a short time to one of their two DE counterparts (either X or Y). By symmetry, DE particles tunneling would be turning (half of the time) to their counterparts of regular matter. These tunneling DE constituents are suggested to be vacuum fluctuations. It is argued that this could provide an explanation for the Vacuum Catastrophe and offer a prediction for the vacuum energy density: Its particle density should be equal to that of all RM and DM particles tunneling at any given moment. Subsequently, one can place a LAN of átmita inside another LAN, rather than in empty space. DM particles are argued to be comprised of X- or Y-based LANs inside a Z-based LAN, whereas RM particles to be Z-based LANs inside a Z substrate. Since both DM and RM particles have Z-based substrates, it is shown that they can interact gravitationally. Based on their (a)symmetry, the percentage of DM is found to be 80% of Ωm, i.e., Ωc=0.26¯, in agreement with the value reported by Planck Collaboration (Ωc=0.264±0.011). Finally, we survey the structure of all Zz particle types. Each one is identified to correspond to a known (first generation) particle of the Standard Model. Their basic characteristics are studied, in terms of charge, spin, possession of mass, stability, etc. It is predicted that neutrinos are Dirac, not Majorana particles and that the W± bosons, but not Z0, might be able to interact with DM particles, possibly offering an explanation for the recent anomalous measurement of their masses. Also, each Force (except for the Strong) is associated with a specific LAN surface and their strength hierarchy is suggested to stem from the relevant hierarchy of the distances of these surfaces from the particle’s router.
