String Theory Models Positive Vacuum Energy

Physicists Bruno Bento and Miguel Montero recently constructed an explicit string theory model that yields positive vacuum energy (de Sitter space), addressing dark energy and cosmic acceleration. Their approach stabilizes fluxes and branes to produce a long-lived de Sitter vacuum, countering prior no-go results and engaging swampland debates. If robust, it enables testable cosmological predictions and advances quantum gravity research.
