The grid mesh visualizes spatial curvature: flat (Ωk=0), open/saddle (Ωk>0), or closed/spherical (Ωk<0). Dark matter's extra gravity seeds galaxy clusters — the glowing particle field clumps more strongly as the dark matter fraction rises. Inflation shows a brief exponential space-stretch right after the Big Bang.
Ωm + ΩΛ + Ωk = 1
Closed (Ωk<0): eventual recollapse ("Big Crunch")
Open/Flat + ΩΛ>0: eternal accelerating expansion ("Heat Death")
- Universe geometry — sets the curvature term Ωk and bends the reference grid accordingly.
- Dark matter fraction — strengthens gravitational clumping of the large-scale structure particles.
- Fast-forward speed — advances cosmic time faster to reveal long-term fate.
- Trigger Inflation Epoch — replays a brief exponential expansion burst, as in the first 10⁻³² seconds after the Big Bang.
Real-world application: precision measurements of the CMB (Planck satellite) show our universe is measured flat to within 0.4%, with a dark-energy-dominated accelerating fate.
