Black holes have always been a mystery to me, but that also makes it so interesting. Now, what is a black hole? I wasn’t so sure of it either and had to research it myself. The definition of a black hole that the internet provided me with was an “Astronomical object so massive that anything falling into it, including light, cannot escape its gravity.” Just like how everything in the universe has gravity, so does the cause or seed of a black hole. To be clear, a black hole is not a matter like a planet or a star is. It is a place or an area in space where the gravity is too strong to escape. In the center of this “place” is the cause of the massive gravity, which is usually a matter that has been squeezed into a tiny space. A black hole is usually something that occurs when a star dies, and because even light cannot escape its gravity, a black hole appears black or invisible. With a special tool, however, you can find visually see black holes in space.
The size of a black hole varies greatly. The smallest black hole can be as small as just one atom, but its mass can be much larger, almost equivalent to the mass of a mountain. On the other hand, the world’s largest black hole ever discovered is so enormous that it cannot be described or measured. It has a mass of 1.6 billion suns and is located more than 13 billion light-years away from Earth, at the center of the universe. This black hole, also called the quasar, is thought to have been around since when the universe was only 670 million years old (which is only 5% of the universe’s current age). The discovery of quasar, which again was the first discovery of a black hole, was very significant to the scientists because the existence of such a thing called a black hole was first known to humans.
Although black holes are known to grow over time as they gobble matters around them, this black hole has been calculated that must have been at a starting mass of at least 10,000 suns. This explains that this particular black hole could not have been originated from the collapse of a star because a star can create black holes only a few thousand times more massive than the sun. XCiaohui Fan, a study co-author and an astronomer at the University of Arizona in Tucson, hypothesized that the seed of this massive black hole must have formed through “the direct collapse of vast amounts of primordial hydrogen gas.” Or another possible guess, maybe that these black holes can grow at a much more rapid speed than the scientist assumed. There are so many possibilities and hypotheses, but nothing has been yet to be proven.
