Example input
Black holes are very interesting objects in space. They are called black holes because they do not let any light escape from them. They are formed when a star dies and collapses in on itself. The gravity of a black hole is so strong that not even light can escape from it, making it invisible to telescopes. Scientists have been studying black holes for many years to learn more about them. They have found that black holes can be very large or very small. The size of a black hole depends on how much matter it contains. The larger the amount of matter, the larger the black hole will be. Black holes are also very powerful. They have a strong gravitational pull that can even affect nearby stars and planets. If a star gets too close to a black hole, it can be pulled in and destroyed. This is called a "spaghettification" because the star gets stretched out into long, thin strands. In conclusion, black holes are fascinating objects in space that have captured the imagination of scientists and the public alike. Despite their mysterious nature, we continue to learn more about them every day and they offer a unique opportunity to better understand the workings of the universe.
