Scientists just found the super-massive quasar with a super-massive appetite, making it the “cookie monster” of astronomy. Astronomers discovered the fastest-growing black hole ever observed in the entire universe, and it is growing with such a remarkable speed that it can swallow two stars as big as the sun in every 48 hours.
This ultra-massive celestial object was first flagged by the scientists at the Australian National University based on the data gathered from telescope, SkyMapper. They used data from another satellite, European Space Agency’s Gaia Satellite, to find out its distance from the Earth. Evidently, by looking at this gigantic black hole, we are looking back over 12 billion years. This means we can now observe the cosmic dark ages of our universe. Moreover, according to scientists, this discovery questions some fundamentals about the science of the black holes. To determine how a black hole grows, scientists use speed limit formula. Every black hole has speed limit, which is proportionate to its mass. According to the speed limit formula, this new found black hole’s size is as big as the size of 20 billion suns. Therefore, more than 1.2 billion years ago, when the black hole was born, it was of the size of 5,000 suns. However, till now, scientists have observed that the scope of the average black holes is around 50 suns. Therefore, scientists are banging their heads thinking how this gigantic black hole became so… gigantic.
Christian Wolf, the lead author on the study said, “The light we see is the heat radiation from the matter falling into black hole, which is a few thousand times brighter than our Milky Way galaxy.” Moreover, he suspects two possibilities. One, the black holes can develop more rapidly than the speed limit, which scientists do not know how. Two, in the period of Big Bang, black holes as big as 5,000 suns were created in a mysterious way. However, we don’t know what was exactly going on during the early eons of the universe. Therefore, this discovery shades a little light on the Big Bang.
Wolf explained that though these are black holes, they have ability to shine, and therefore, can be used to study the formation of elements at the beginning of the universe. He said, “Scientists can observe the shadows of celestial objects in front of this ultra-massive black hole. Moreover, such massive black holes help to clear the fog around the revolving objects by ionizing gases, which makes the universe more transparent.” However, these are just theories without any significant proof.
It seems that the discovery of such super-massive black holes is creating more questions instead of solving the puzzle of Big Bang. Furthermore, there must be more gigantic black holes in the universe camouflaging themselves. Scientists must have overlooked them due to their unusual brightness till now. Therefore, researchers must continue the hunting for such massive black holes to understand the mystery of the origin of super-massive black holes.
