While scientists might confess that all the phenomena of the great universe allow for harmony (and resonance) to exist as a mathematical possibility or outcome, harmony is seen as the exception and not as the rule by which universal process unfolds itself and gains greater complexity.
But the physical world came into existence only because order and increased organization came into existence. Existence is relationship and is reflexive. Furthermore, there can be no relationship without harmony.
Cosmic organization and order requires that harmony can even govern and direct the laws of gravity. For instance, every physicist knows that when an object is put into motion it will seek its own particular equilibrium or state of stability.
When we then look at all the processes occurring in complex organic forms we see a profound harmony at work—parts, actions and individual motions being orchestrated in marvelous ways so that all their states of stability tend towards a common equilibrium (like music). A “dead” universe of matter cannot do that—even when the dice are somehow, mysteriously loaded!
So, harmony allows for the cooperation of successive, and thus, simultaneous processes to occur within the essence-principle of generating a complex structure. (Even our mental thoughts must come under this harmonic design to create a coherent belief system—psychical complexity)
According to scientist/theologian Emanuel Swedenborg, harmony is a physical representation of the spiritual principle of Love. (Most physical scientists will not go there! Too bad…)
