The world is sound. Tesla was right, "energy, frequency, vibration." What is sound? Vibration.
There's even a book by the name: The World Is Sound, by Nada Brahma. Interesting read.
Nassim Harrmein came up with the math demonstrating its pixels instead of string. Matter is made up of vibrating pixels (I forget what he calls them, posting on the fly here.) He has a Facebook page. The math works out geometrically as the Flower of Life. Sacred Geometry.
