Black Holes

Black holes, technically, are still not proven to exist but there is an exploding amount of evidence that they do. They were first calculated mathematically in the late 1700s and, since then, are still being studied. Even though we can’t see them, we know that they do exist. In fact, they were first named “invisible stars,” since these calculations showed that they have an exceedingly massive and therefore light can’t escape from it. Black holes are formed from very large, old stars that explode into a supernova and then collapse. When they collapse, all that hydrogen and helium gas compresses back inward so forcefully that it forms a really massive “hole” of which nothing can escape.
Usually, we think that the bigger something is, the more powerful it will be, and this proves itself right in some situations. But that is not always not true and especially with black holes. Actually, the smaller the black hole is, the more massive and powerful they are. It is theorized that some black holes, which suck up whole galaxies and stars 10,000 times our own star’s size, are no bigger than the size of a potato chip. Black holes maybe very small but are certainly very influential. These are one of the qualities that build a person’s curiosity about these super massive holes. It leaves us all in awe how something so small can be so powerful that not even light can escape from it. It will guzzle up anything that comes near it. In the end, it leaves you to wonder where all that material ends up. Is it lost forever in a dimension or hole, or does it end up somewhere else in the universe?
