# Calculation of the average 11-year period solar cycle by the gravitational parameters of the Sun/Earth, the fundamental physical constants and the "golden" number φ

The first calculation formula (in the first approximation) is the following:

where aS ≈ 2.4976·1020 m is the distance from the Sun to the Galaxy's (the Milky Way) center, c = 299792458 m/s is the speed of light in vacuum (in the sphere of action of the Earth), µS ≈ 1.3271·1020 m3/s2 is the reference value of the gravitational parameter of the Sun, µE ≈ 3.9860·1014 m3/s2 is the reference value of the gravitational parameter of the Earth (the geocentric gravitational constant).

This equation, calculating the average 11-year period solar cycle, is based on the hypothesis according to which the Sun moving along its galactic orbit periodically emits ultra-long electromagnetic waves moving at the speed cS ≈ 1.44·1012 m/s that are reflected from the center of the Galaxy and return back to the Sun:

Also, empirically I managed to derive another approximate equation for calculating the average 11-year solar cycle using the fundamental physical constants and the "golden" number φ

where aS is the distance from the Sun to the Galaxy's (the Milky Way) center, c is the speed of light in vacuum (in the sphere of action of the Earth), φ = (1+√5)/2 ≈ 1.618 is the "golden" number, me/mp is the mass ratio of electron to proton.

In fact, I think these equations may be interpreted as an indirect evidence of the connection between the macro- and micro-world. In this world, there are no such coincidences.
