The outer space contains larger amount of black holes in terms of size and quantity. In the center of our galaxy the supermassive black holes have the mass of about 4 million suns but still it is small compared to galactic black holes. Galactic black holes have the masses of billions of solar and the extreme massive black hole found till now is estimated to have the mass of 70 billion suns. Just think how more can a black hole still get?
What a black hole needs to do in order to become massive? simple, it needs to consume large amount of matter in its early life. Because if it consumes slowly what happens is its surrounding galaxy will starts growing and settled itself into expanded universe and due to this black hole can’t be able to capture more matter. But also if the black hole has consumed large number of matter so quickly than this matter get super-hot and it will push the other matter away by which a black hole cannot grow more further.
The observations that has been carried out on the largest black holes and also the simulations on how the black holes formed gives a thought that the upper mass limit of the galactic black holes is expected to be around 100 billion solar masses. But the recent study shows that limit could be much higher.
The research team tells that the noted limit of solar mass of the galactic black hole is 100 billion and the larger black holes are formed independently during their early days. This ancient black holes have more mass of million times larger than the largest cosmic black holes. And this types of black holes are termed as Stupendously Large Black Holes or SLABs.
The idea behind the ancient black holes has been around since long as it is a solution of all the questions from dark matter to the hiding of imaginary ninth planet in our solar system. According to the theoretical models primitive black holes are even smaller than the stellar mass black holes that are formed by tiny density fluctuations in the early universe. Recent research shows that some of the factors make them to grow stupendously large.
A primitive black hole could have consumed large amount of dark matter to grow but in the early universe a form of dark matter known as Weakly Interacting Massive Particles (WIMPs) that doesn’t interact strongly with the light and because of that it doesn’t emit much light or heat that decrease the growth rate. Basically according to this the upper mass limit of the SLABs totally depends on WIMP dark matter interaction. So to understand the dark matter in detail it necessary to find the Stupendously Large Black Hole.
Till now the Stupendously Large Black Holes have not been observed yet as may be they are hiding in the hearts of distant galaxies or even they could be hiding between the galactic clusters or maybe they don’t exist and to find one is going to be the historic discovery.
