Universal Thinning is the fundamental process where the "Physical Sea" (the energy-dense medium of space) loses density over time. In this model, the expansion of the universe is not the creation of new space, but the decompression and thinning of the existing medium.
The density of the Physical Sea at any time can be modeled as a decay function.
Exponential Decay:
Where is the initial density and is the thinning constant.
Reciprocal Decay:
The thinning is mathematically described by the divergence of the velocity field of the Sea.
The Eigenvalue ():
Locally, the eigenvalue of the velocity gradient tensor represents the Hubble Parameter ().
Divergence Relation:
In a homogenous thinning field, .
