A cosmological framework that treats the universe’s large‑scale expansion and potential future contraction not as passive consequences of initial conditions but as active, competing principles. Expansionist forces (dark energy, inflation) push spacetime outward, increasing distances and diluting matter; contractionist forces (gravity, dark matter) pull it inward, potentially leading to a “Big Crunch.” The theory models the history and future of the cosmos as a dynamic tension between these two tendencies, with possible cyclic phases. It also explores local variations—regions that expand while others contract—and the implications for structure formation and the ultimate fate of the universe.
