New observations hint that dark energy—the mysterious force accelerating the universe’s expansion—may weaken over time, challenging the long-standing assumption that it is constant. If confirmed, this shift could redefine our understanding of cosmic history and destiny. Upcoming surveys promise sharper data that may reveal whether the universe is evolving in ways we never expected.
