Thinking about it, I have come across bits and pieces of that theory in my reading. Sure that seems possible to me. 'Endlessly reversed entropy' would neither have a cause (causeless) nor a purpose to it (meaningless) and would essentially be both timeless and eternal.
On your point about poetry, I think serious art should cover one of these four-fold themes:
1) the psychological
2) the sociological
3) the existential (philosophical)
4) the sublime
Many of these thematic items crisscross into different registers. Both the psychological and sociological themes merge together into existential narratives. Also this four-fold matrix, further splits into 'inner' and 'outer' indexes forming a thematic octave of ideas. I think it's great that you tackle these cosmological and metaphysical subjects - and the ideas you express are fascinating.
Presently, I am writing works on sociological topics - my poems are attempting to act as anthropological mirrors - reflecting what is happening in society and the psychological impact of these crises. I love both existential and metaphysical poetry and would love to write on these themes also. The sonnet, Geomancer was an attempt I made to tackle these difficult and perplexing subjects. I agree my friend, poetry should 'advance' our lives in some way.
Notwithstanding everything, it seems to me that all things are 'interconnected' with the Mystery. As for coincidence? Either everything falls under that massive galactic umbrella or nothing does, depends on how you argue it and the subtleties of such a discourse you present.
As always you present a banquet of thought,
