Speed of Energy as Local Field Behavior

Concept Summary

In the Charge Admittance (CA) framework, the speed of light is not a universal invariant imposed from above — it is a local material property of the field. Specifically, the speed at which energy propagates through space is determined by the structure of the vacuum, namely its permittivity ( $\varepsilon_0$ ) and permeability ( $\mu_0$ ), both of which can vary spatially and temporally in response to energy events and coherence structures.

This redefinition reframes $c$ not as a cosmic speed limit, but as an emergent behavior of the medium’s current state.

Key Expression:

$c(x) = \frac{1}{\sqrt{\mu_0(x) \, \varepsilon_0(x)}}$

Where:

$c(x)$ is the local energy propagation speed at position $x$
$\mu_0(x)$ is the local permeability of the vacuum
$\varepsilon_0(x)$ is the local permittivity of the vacuum

Interpretation:

If $\varepsilon_0$ or $\mu_0$ increases due to local field structuring, $c$ decreases.
This spatial variation in $c$ leads to observable gravitational-like behaviors, redshifts, and temporal offsets — without invoking spacetime curvature.
Local changes in structure translate directly to changes in how fast information and energy propagate.

Implication:

The so-called “speed of light” is no longer sacred — it is responsive.
This explains gravitational lensing, Shapiro delay, and Pound-Rebka time dilation not as curvature effects, but as slowing of energy motion through a structured vacuum.
CA unifies electromagnetic and gravitational effects under a single, dynamic propagation model governed by local field impedance.
