Black holes are regions of spacetime exhibiting gravitational acceleration so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. 1. The term black hole was first coined by physicist John Archibald Wheeler in 1967. 2. The nearest known black hole to us is V616 Monocerotis, located around 1,000 light-years away. 3. The largest known black hole, named TON 618, has a mass over 66 billion times that of our sun. 4. Despite their reputation for consuming everything in their path, black holes can also give off radiation, known as Hawking radiation. 5. Black holes can merge together, creating even larger black holes. 6. There is a supermassive black hole at the center of our own Milky Way galaxy, called Sagittarius A, which has a mass of about 4 million times that of our sun. 7. The extreme gravitational forces near a black hole can cause time dilation, where time appears to pass differently depending on your distance from the black hole. 8. Some theories suggest that black holes could potentially be used as a source of energy in the far future, through technologies like black hole farming. 9. Black holes are not actually holes in space but rather incredibly dense objects with huge gravitational pull. 10. The study of black holes has revolutionized our understanding of the universe and continues to be a major area of research in modern astronomy.
