Eclipses: Crossing sound waves create Constructive or destructive interference.

Lunar eclipse: Two sound waves. When they match each other in a way where one is in the peak and the other wave matches it, also in the peak (or they could both be in the trough), its called constructive interference. And when that happens,
more amplitude happens. We see different light colors.

“Light is no more than a sound wave of the aether.” -Nikola Tesla

Solar Eclipse:

Sun and moon are both sound waves. When they cross each to where one wave is in the trough and the other is in the peak, they cancel each other out. It’s called destructive interference. A moment of no sound would create a moment of darkness in the aether. The moon would likely would cross through the sun’s sound wave. (Not in front or behind).
