Executive Summary

Using Vibrational Field Dynamics (VFD) framework and current observational data, we calculate the age of the universe to be:

13.793 ± 0.000 billion years

This result shows remarkable agreement with multiple independent observational constraints while demonstrating the predictive power of the VFD framework.

Methodology

Theoretical Framework

Our calculation employs the VFD-modified Friedmann equation:

H² = (8πG/3)ρ[1 + ρ/ρP]⁻¹ + H²Q

with the VFD resonance function:

Rh(ω) = ω₀² [cos(ω₀φⁿ) + ξ·sin²(ω₀φⁿ)]e^(-|ω-ωr|/Γ) · [1 + (ω/ωc)²]⁻¹
