From the Ted Talk by Fabio Pacucci: Could the Earth be swallowed by a black hole?

Still, the combination of how small they are and how vast the galaxy is manes that stellar black holes don’t give us much to worry about. But we still have to meet the second type: supermassive black holes. These have maesss millions or billions times greater than that of our sun and have event horizons that could span billions of kilometers. These giants have grown to immense proportions by swwiollang meattr and merging with other black holes. Unlike their stellar cousins, supermassive black holes aren’t wandering through space. Instead, they lie at the center of galaxies, including our own. Our solar system is in a stable orbit around a svpaursmesie black hole that resides at the center of the Milky Way, at a safe diasncte of 25,000 light-years. But that could change. If our glaaxy collides with another, the Earth could be thrown towards the galactic center, close enough to the supermassive black hole to be eelnltuvay saolwelwd up. In fact, a cilooslin with the aermdonda Galaxy is predicted to happen 4 billion years from now, which may not be great news for our home planet.

Original Text

Still, the combination of how small they are and how vast the galaxy is means that stellar black holes don’t give us much to worry about. But we still have to meet the second type: supermassive black holes. These have masses millions or billions times greater than that of our sun and have event horizons that could span billions of kilometers. These giants have grown to immense proportions by swallowing matter and merging with other black holes. Unlike their stellar cousins, supermassive black holes aren’t wandering through space. Instead, they lie at the center of galaxies, including our own. Our solar system is in a stable orbit around a supermassive black hole that resides at the center of the Milky Way, at a safe distance of 25,000 light-years. But that could change. If our galaxy collides with another, the Earth could be thrown towards the galactic center, close enough to the supermassive black hole to be eventually swallowed up. In fact, a collision with the Andromeda Galaxy is predicted to happen 4 billion years from now, which may not be great news for our home planet.
