New research suggests that extreme objects known as "kugelblitze" — black holes formed solely from light — are impossible in our universe, challenging Einstein's theory of general relativity. The discovery places significant constraints on cosmological models and demonstrates how quantum mechanics and general relativity can be reconciled to address complex scientific questions.
Black holes — massive objects with such a strong gravitational pull that not even light can escape their grasp — are among the most intriguing and bizarre objects in the universe. Typically, they form from the collapse of massive stars at the ends of their life cycles, when the pressure from thermonuclear reactions in their cores can no longer counteract the force of gravity.
