“If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.” ― Nikola Tesla
Over the years, I've collected a lot of unusual rocks, being always amazed at what appeared to be an intelligent design in nature. Particularly interesting to me were these examples of what is known as liesegang rings in stone.

The official geological explanation of how these rings were formed in these rocks might be attributed to this material's chemistry or perhaps the prolonged weathering upon it, but the particular shape and size of the formations of the geometry throughout the stone's structure are not easily explained in traditional geological terms.

Could these formations have been caused by the vibrations of sound?
Cymatics, Vibration, and Resonance
By sending vibrations into a metal plate using various sound frequencies, the actual shape of sound can then be seen in a two-dimensional representation when salt or sand is scattered onto the vibrating plate. By changing the tone of the note that is shivering the metal plate, the patterns will change accordingly, giving a glimpse of how particular sounds can manipulate the structure of space, or perhaps give some structure to a space.
Here's one of many videos that can be found on the internet showing some of the patterns that are formed under the influence of sound, a process known as cymatics:

Manipulation of Gravity Through Acoustics
If sound can influence gravity, then it becomes easier to imagine a puddle of mud being shaped by an acoustic jolt, a big noise which might compel the heavier, denser particles in the mud to gather within the distinct cells like an acoustic kaleidoscope.
This notion takes me back to those unusual rocks in my garden, but while cymatics could be a way to explain how the rocks were shaped, the hypothesis raises another question: Where did the big sound come from?

Was it a big noise that shaped these stones, or is there a more complicated process which would explain these distinct patterns in geology?

Here's another interesting cymatics video, exploring the possibilities of how our world was formed, and showing how experimental worlds can be formed using nothing but frequency and vibration.

Maybe our world is actually held together by a big note, and perhaps it was formed by a gigantic song hummed through the cosmos, giving math and geometry to an otherwise misshapen blob of mud and clay.
If this planet experienced an acoustic event in the past, will that big noise ever return? Or is it still here, humming along so naturally that we don't hear it anymore?

There was a time when I looked at these rocks and had no clue how they were shaped, but now that we have the internet, and with all of the information in the world at our fingertips, we can find the idea of cymatics and frequencies, and we might start to think in terms of vibration and sound as a way to describe the universe and the planet we live upon. If nothing else, the idea of acoustics and cymatics might finally help me to explain the shape of these funky garden rocks.
