The Weinberg-Salam parameter [math]sin^2\theta[/math] for electroweak unification gives a mixing angle indicating the angular distance between the positive and negative time axes using the following trigonometric identity
[math] sin^2\theta \equiv 1-cos^2\theta[/math]
And the particular optimizing value happens to be 90 degrees. This indicates that the dual time axes (positive and negative) for each particle found in spacetime are orthogonal. This suggests that, in conformation to the geometry of a light cone, the so called negative time axis corresponds to the one dimensional space axis.
Strictly speaking, from the quantization of spacetime viewpoint, there exist two intrinsic angles derivable from the square of energy.
[math]E^2=\vert \psi_1\psi_2\phi_1\phi_2\vert sin\theta_1 sin\theta_2[/math]
Furthermore, the three congruences of (1) [math]\theta_1 \cong \theta_2 [/math], (2) [math]\psi_1 \cong \psi_2 [/math], and (3) [math]\phi_1 \cong \phi_2 [/math] establish the consistency between [math]E^2[/math] and Weinberg-Salam parameter of [math]sin^2\theta[/math]. However, only congruence 1 is necessary. Nevertheless, when [math] \vert \psi_1\psi_2\phi_1\phi_2\vert = 1 [/math], implying [math] \psi_1 = \frac{1}{\psi_2}[/math] and [math]\phi_1 = \frac{1}{\phi_2} [/math], the Weinberg-Salam parameter is equivalent to the square of energy.
