Black Holes grows after Big-Bang

Black Holes grows after Big Bang:

Black Holes Grows after Big Bang. Supermassive black holes are now known to be present at the center of the majority, if not all, galaxies. These cosmic titans have masses millions or even billions of times greater than the sun, but despite their enormous size, supermassive black holes, which are more common in the local universe and therefore more recent in cosmic history, don’t pose a threat.

However, supermassive black holes become a problem when they are observed in the early universe and have masses that are comparable to billions of suns. This is due to the fact that supermassive black holes must have some mechanism allowing them to rapidly gather mass and grow to such enormous sizes, but all of the currently known mechanisms for this growth suggest that this process proceeds too slowly for objects like these to exist just yet.

According to John Reagan, a Royal Society University Research Fellow at Maynooth University, “over the last two decades, astronomers have discovered supermassive black holes with the same masses as in the local and thus more recent universe — billions of solar masses — almost 13 billion years ago, less than a billion years after the Big Bang.”

Regan uses a disturbing analogy to describe the issue. It’s comparable to observing a family walking down the street with two six-foot teenagers and a six-foot toddler in tow. That poses a slight issue—how did the child grow to be so tall? The same holds true for the universe’s supermassive black holes.

The most remote and ancient supermassive black hole was found this year by the James Webb Space Telescope (JWST), which further complicated the situation. This black hole, which is at the center of the galaxy CEERS 1019, however, is comparatively small for a supermassive black hole because it has a mass 9 million times that of the sun.

Even so, the fact that this black hole exists only 570 million years after the Big Bang casts doubt on theories about how black holes grow. And it wasn’t just this 9 million solar mass black hole. The Cosmic Evolution Early Release Science (CEERS) Survey, the observing campaign that discovered this supermassive black hole, also found two other supermassive black holes that were both 1 billion years and 1.1 billion years old.

According to professor Shantanu Basu of the Canadian University of Western Ontario, “the constraints on our existing ideas become stronger with each new discovery.” “When supermassive black holes were discovered 800 million years after the Big Bang, we became concerned. The challenge is just greatly heightened by CEERS.

This puts more pressure on the search for a mechanism to explain how they got there because it suggests that supermassive black holes are not some cosmic rarity but rather common in the relative infancy of the universe.
