The Acta Universi (AU-field) hypothesis, proposed by D. E. Yashchenko in 2025, is a speculative theoretical framework that reinterprets dark energy as a dynamic informational archive of all events in the Universe — the AU-field. Dark energy (≈68% of the Universe's energy density) is not merely a cosmological constant Λ or quintessence, but a universal "database" or matrix of correlations recording all irreversible acts and interactions (from quantum fluctuations to galaxy mergers). This leads to exponential growth in structural complexity and generates antigravity repulsion, explaining the accelerated expansion of the Universe. In this picture, spacetime "collapses" into a phase space of correlations and fluctuations: objects and events exist "everywhere and always" informationally. Classical motion is a "rewrite" in this archive rather than physical displacement. The hypothesis integrates cosmology, quantum mechanics, information theory, the holographic principle, and elements of quan
