James Webb discovered a giant black hole that fell asleep!

The James Webb Space Telescope has discovered a massive supermassive black hole that existed in the early universe, when the universe was only 800 million years old. The discovery, published in the journal Nature, aroused great interest in the scientific world. In addition to having a mass equivalent to 400 million times the mass of the Sun, the black hole was recorded as one of the largest black holes observed at that time. Here are the details…

James Webb telescope discovers a cosmic ‘sleeping giant’ black hole

First of all, let’s point out that this huge black hole is currently in a “sleeping” state, that is, it is not actively swallowing matter. However, it is estimated that it grew by feeding its galaxy in the past. Interestingly, this black hole accounts for 40% of the total galaxy mass of its host. This rate has surprised scientists as it is generally around 0.1% in the modern universe.

According to scientists, such supermassive black holes go through intense growth and long rest phases. Researchers say black holes are “Eddington LimitHe thinks that they went through intense growth phases lasting 5 to 10 million years, exceeding their capacity to absorb matter, known as the “matter”, and then entered a period of stagnation for 100 million years.

In short, this discovery also showed that the early universe may have contained many dormant supermassive black holes. But these “silent” giants are very difficult to detect. Researchers say more such discoveries may be possible thanks to the sensitive observations of the James Webb Telescope.
