Usually, black holes tear apart anything that approaches the horizon. But new work showed: if dark energy exists in the universe, a falling object could remain intact. So, the mysterious expansion of the cosmos can protect against destructive tidal forces.

🎯 The supermassive black hole Sagittarius A* at the center of the Milky Way holds onto a gas cloud, despite cosmic expansion—its gravity is stronger than the cosmic stretching.

🎬 In “Interstellar,” astronauts survive inside a black hole; perhaps dark energy in their universe acted as an invisible guardian.
