How big can a supermassive black hole (SMBH) get? A new estimate suggests absolutely plenty of freaking- or more high-brow phrasing them, “stupendously large.“ Depending on how big these ocean bodies could be – the task was to understand and try to put up some obstacles. In a study published in the Royal Astronomical Society’s Monthly Notices, researchers explored the potential properties, structure, and effects of this disproportionately large black hole, or SLABs.
Researchers have argued that there is no evidence for the existence of black holes that are larger than what we see at the center of the largest galaxy. That said, we don’t know how SMBHs form and there is almost speculation about the physical upper limit of their size, but it’s interesting to see what can happen outside of it without a fixed limit. The standard range for SMBHs will move from the size of the Milky Way to the size of our galaxy at one million speeds. The lowest limit we have ever discovered is 25 times larger than the largest SMBH.
Lead author Professor Bernard Carr from the Queen Mary University of London said in a statement, “We already know that black holes are over a wide mass of people, with an SMBH of four million solar masses at the center of our own galaxy.
Although there is currently no evidence of the existence of SLBS, it is possible that they may exist and that they may be spread out of the galaxy with interesting observational consequences. However, surprisingly, the concept of SLBS is still neglected.” “We’ve proposed alternatives to how these SLBs can be structured and hopefully our work will start to inspire discussion within the community.” We know that these things are not likely to get so big in the age of the universe, so one possible consideration is that they have always been here. There are ideas that immediately after the Big Bang there were conditions that would help form black holes.
These primitive black holes have been called upon to explain the dark matter, the rapid formation of superhuman black holes, and our other questions about the universe. But can we have any limitations? An interesting one is imagining that these objects are formed everywhere and they spread all over the world. These huge objects will significantly affect the speed of galaxies. Based on these ideas and the speed of the Milky Way, the team was able to estimate that if only one of these SLBs were present, it would be the largest of all time – about a billion times the Milky Way.
Another limitation is the effect of these primitive slabs on the cosmic microwave background shining the primordial SLABs of the universe. Anything 100 times larger than the Milky Way will leave a clear mark, so it’s a more reasonable ranger to consider. Black holes are not easy to detect, but these SLABs will have a gravitational effect. Nothing has been announced yet, so there is probably a higher limit to how large black holes can be found, and we haven’t found it yet.
