A miss-read of entropy. That matter should prefer to move from a more complex state to a lesser state unless energy is applied. Entropy law works fine - but only in a pure vacuum is there a complete lack of external energetics. Also, you apply entropy in the absence of conservation of matter and energy. If nothing were truly the composition of the universe then nothing would remain, well, nothing.
“Entropy law works fine - but only in a pure vacuum is there a complete lack of external energetics.”
Is there really anywhere you can say there is no external input? It’s basic science that every piece of matter in the universe exerts a gravitational force on every other piece of matter in the universe. The effect may be so infintesimal, you don’t need to account for it in calculations, but it is still there. Ditto for electromagnetic fields that expand outwards to infinity in all directions.
