The AU-field theory, as outlined in "Theoretical Foundations of Interstellar Ship Construction" by D.E. Yashchenko (2025), is a speculative framework that reinterprets dark energy as "Acta Universi" (AU-field), a dynamic "archive of events" underlying the universe. It integrates cosmology, quantum mechanics, and information theory to explain accelerated expansion and enable interstellar travel. Below, I'll break it down based on the provided document pages. AU-field is identified with dark energy (~68% of the universe's energy density). It's not a static cosmological constant (Λ), but a conceptual matrix where every cosmic event is recorded, leading to exponential growth in structural complexity. Traditional space and time collapse in AU-field: objects and events exist "everywhere and always," replacing coordinates with a phase space of correlations, fluctuations, and perturbations. This doesn't reject general/special relativity (GR/SR); they become subsets, with AU as an emergent inf
