Potato Sack Cosmology is a unifying framework that treats dark matter lensing, dark energy’s late-time push, matter–antimatter asymmetry, and cosmic expansion anomalies as evidence of a single underlying tension field. By interpreting these puzzles together rather than in isolation, PSC provides testable predictions that connect four of physics’ deepest mysteries under one measurable model. It’s called Potato Sack Cosmology because from our perspective, the universe's spacetime behaves like a sack — its dents, bulges, and tensions reveal the hidden forces we mistake as dark matter and dark energy.
