Freaking Out About Tesla's Frequencies Interesting years ago I presented to an Astronomer friend about my theory the universe is organized by sound frequencies and he pointed out that sound can't travel in a vacuum! And that put an end to my theorizing about sound frequencies but I can resonate with Tesla's statement "Our entire biological system, the brain and earth itself, work on the same frequencies"
It’s not just sound that resonates. https://physics.stackexchange.com/questions/488705/how-far-can-radio-waves-travel-in-vacuum-and-light-waves
