This simulation shows primordial energy explosion—a concentrated point releases energy that propagates radially outward. The field evolves naturally: energy spreads, diffuses, and conserves. No external expansion mechanism, no spacetime curvature—just lattice field dynamics from a singularity.

• Central singularity — Energy concentrated at lattice center (r=0)
• Explosive release — Radial velocity field drives outward expansion
• Energy conservation — Total field energy remains approximately constant (with viscosity)
• Shell formation — Energy propagates as expanding wave front
• Natural evolution — LFM dynamics govern spread, no ad-hoc inflation

🔬 Pure LFM Big Bang: This is a minimal demonstration of energy explosion from a point. Real cosmology requires quantum fluctuations, matter/radiation separation, dark energy, and baryogenesis. This shows the principle: concentrated field energy can explode and evolve into structure—all from lattice dynamics with no external driver.
