Researchers analyzing 2,884 exploding stars published findings on October 23, 2026 suggesting that dark energy, the mysterious force driving the universe's accelerating expansion, may not be constant as long assumed. The large-scale survey challenges a foundational assumption of modern cosmology that has underpinned models of the universe for decades. If confirmed, the result could force scientists to revise standard models of cosmic expansion and the ultimate fate of the universe, making it one of the more consequential cosmology findings of the year.
