Black hole is a spots in the universe that cannot be escaped by light because the gravity is very strong. One of the black holes that confuses astronomers is how large they are. Researchers explain one category of black holes over 100,000 to 10,000,000,000,000,000 times, like the sun. Super Massive Black Hall。 These black holes are very large, so Whole galaxy! It generally exists in the center of the galaxy, including ourselves milky wayOur thing is a modest 4,000,000 sun. Scientists are wondering if the universe, which was formed only in the universe, has grown very much. 13.7 billion years ago Big bang.
Considering that the earth is only growing, it may seem like enough time for a huge heavenly object to grow. 4.5 billion years old. However, when they are formed, black holes can only be enlarged by fusing with others or waiting for things to fall. Astronomer estimates it Many black holes are fused every yearbut Only Super Massive Black Hall will join Rarely. Astronomers who use mathematics models for these events calculate that they can be taken. There were more time than the universe.。
Gas and dust falling in the black hole, Light flashing attachedIt also occurs slowly to explain the growth of the ultra -high MASSIVE black hole. For example, our Galaxy's super huge black hole grows with just one sun. 3,000 years。 However, assuming that the black hole grows at a constant speed, the huge hole has had to increase the mass of the sun more than the value of the sun every year since the Big Bang.
To solve this problem, astronomers theorize how Black Hall was born in the early universe. Super Massive Black Hall requires a good start compared to the conventional black hole cousin. There is a sun from 10S to 100 years。 Thus, astronomers assume that many black holes and many 100,000 solar sun must have been formed early in the universe. They call these early black holes seed。 Roughly speaking, astronomers propose two potential origin, a black hole species. Giant clouds of dust It collapses directly into the black hole Population III star explosion.
Columbia University's astronomers have recently explored how the seeds have grown to grow to today's size, and how they have appeared in a very large black hole. The first step of the astronomer was to find an appropriate formula to calculate the initial quantity of black holes. Researchers have indicated that black hole growth is almost completely exponential. Therefore, this astronomer began with a modified index growth ceremony, like the calculation. Compound interest。 He took this type of derivative and determined how fast the black hole grew. Astronomers have assumed that all super -large black holes formed between the Big Bangs between 100 and 200 million years will be formed.
Astronomers selected 132,539 ultra -large black holes with sufficiently measured mass, and calculated the characteristics of seeds using his new formula. He discovered that 54 % of the seeds could be less than 350 times the mass of the sun, and could occur from the explosion of the individual group III stars. Another 40 % was 350-2,000 times the mass of the sun, and only 2,000 to 30,000 times the mass of the sun was about 6 %. He suggested that the latter two categories could cause small seeds that fuse immediately after being formed. He pointed out that these results did not directly exclude the collapse of the dust in black holes, indicating that there was no need to explain the ultra -large black hole we are looking at today. I mentioned.
Astronomers suggested that these ultra -large black holes have accumulated most of their mass in the first 1.5 billion years of the universe. 。 He explained that the universe was very dense at the time. Later, the galaxies were approaching each other, so a large amount of materials could fall into the black hole. He concludes that the ultra -large black hole is ultimately the relic of the primitive universe, and has been in a very different way than today's organic stars, dust clouds, and galaxies. I did it.
