You got it. Entropy subsumes space-time.
Entropy is a logarithmic measure of multiplicity. Multiplicity referes to the number of microstates a system could assume that would, ultimately, precipitate a given macrostate. Thus, a space (Euclidean, Hilbert, or otherwise) is
presumed with "[e]ntropy" (TPTB_need_war), not "subsum[ed]" (TPTB_need_war), for, therewithout, the system would not exist to bare states (neither micro- nor macro-).
Space-time refers to a 4D space. Entropy knows no such limit in dimension. It is dimensionless and occupies all dimensions simultaneously. Choose your illusion (space) frame-of-reference.
