Entropy-Significance – The word entropy is used in different ways for different purposes. In MSR, entropy is used in a broad sense, encompassing thermodynamic, information, and aesthetic sensitivity. MSR posits that entropy is a consequence of significance, which also is used in a broad sense of meaning, aesthetic dynamism, and signal coherence. Loschmidt’s Paradox brings up the question of how the universe could perpetually be in a state of increasing entropy without an initial low entropy to start with. The Sole Entropy Well hypothesis offered here reverses the assumption of entropy as an increasing value so that it is significance which is absolute, and entropy which constitutes a local masking of it, The mask is what is expanding relative to the significance of the totality, but the totality is always gaining back what is lost through perception. Significance is the chunking up of experience made possible by the deprivations and isolations of spacetime diffraction. When we observe the public universe unraveling into entropy, it is our own appreciation of our position in the universe which contributes to the other side of the balance sheet. Entropy and significance are background and foreground, partners in Aion.
