What is a black hole? A black hole is an area of space that has a lot of gravitational pull, and even light can’t escape it. A black hole is created when a star starts to die because of matter being held in a small space. We can’t see black holes because they are invisible. Special tools and space telescopes can see how close a star is and if it acts differently from the other stars around it. Black holes can move around through space, the very big ones stay at the center of their galaxy until something bad happens, like the collision of two galaxies. They could also move by the explosion of the Sagittarius A, which is a black hole in the center of the Milky Way. This black hole can move near Earth, but it won’t be able to for another million or billion more years. It may never happen, but we will never know. Did you know that 3 stars can create a stellar black hole, and the nearest is about 16,000 light years away or more, and there are about 100 million stellar black holes in the Milky Way, and if they stop, then there will be a supernova explosion which is really bad! And yes, there is a thing called a white hole. A white hole is the opposite of a black hole because, while black holes suck in energy and don’t let anything out, white holes don’t suck in anything, but it shoots out the matter that was sucked in through the black hole, and nothing can enter the white hole, only a black hole does that. There are now 2 black holes in the Milky Way, one in the center, while the other one is super big and is also by the center. This is super dangerous if they start to move towards Earth. The 2 black holes in the Milky Way may destroy Earth, while white holes (if they exist) can put us somewhere else, where there is a sun and hopefully not more black holes.
