Hypothesis about the layered structure of space: world, vacuum insulation layer and anti world

ABSTRACT We present a mathematically closed cosmological model of a 4D eternal Universe based on a multilayer brane geometry. Our three-dimensional world is described as a three-layer structure consisting of a matter brane, an insulating vacuum barrier of finite thickness, and an antimatter brane. The model abandons the concept of a single singular Big Bang in favour of permanent, spatially distributed energy and matter injection caused by local quantum-mechanical punctures (instabilities) of the vacuum membrane. When the barrier is locally breached, matter and antimatter come into contact, producing high-intensity annihilation events. We derive the critical energy of barrier breakthrough, analyse the hydrodynamic evolution of the resulting plasma regions within the Sedov–Taylor framework, and demonstrate that the conditions for local thermalisation (optical depths τff 1 and τDC > 1) are satisfied at early stages of remnant expansion. With a single-event energy E single = 1.0 × 1046 J (≈ 0.056 M) and a volume event rate Γ ≈ 3.38 × 107 events Gpc-3 yr-1, the model reproduces the observed energy density of the cosmic microwave background while maintaining statistical isotropy. Spatial variations of barrier thickness naturally generate cosmic voids (thick regions) and filaments/nodes (thin regions). Annihilation-driven shock waves act as efficient triggers for the rapid formation of Population III stars. The model yields testable observational signatures, including a diffuse 511 keV annihilation line with a possible large-scale structure correlation and local anomalies in light-element abundances distinct from standard Big-Bang nucleosynthesis predictions. The construction remains free of an initial singularity and realises a non-equilibrium steady state sustained by continuous interlayer exchange.
