![]() If too many of these IMBHs develop in the same area, they may eventually collide to generate a supermassive black hole in the galaxy's center. Such entities could develop as a result of repeated collisions between stars in a cluster, in a type of chain reaction. Previously, scientists believed that black holes only occurred in tiny and big sizes. Research has shown that midsize or intermediate black holes (IMBHs) probably exist. The third and final primary black hole type is an intermediate or middle-sized black hole. We can directly detect this substance by its gravitational pull on other things, but we cannot observe dark matter directly thus, we do not know what it is made of. Lastly, vast collections of dark matter may give rise to supermassive black holes. Large gas clouds that collide and quickly accrete mass might possibly be to blame.Ī collapsing stellar cluster, or a collection of stars collapsing at once, is a third possibility. It's possible that hundreds or thousands of microscopic black holes can combine to form supermassive black holes. Once these giants have formed, they continue to increase in size by absorbing mass from the gas and dust surrounding them, which is abundant at the core of galaxies. The origin of such massive black holes remains largely a mystery to scientists. It is hypothesized that such black holes reside at the heart of almost every galaxy, including the Milky Way. They are millions or even billions of times more massive than the Sun, the diameter of these giant black holes is around the same. These are the smallest, but that doesn't mean they are benign.Īlthough many little black holes exist in the cosmos, supermassive black holes predominate. The first and most enigmatic are called stellar black holes. How many types of black holes are there?Īs far as scientists have been able to ascertain, there appear to be three main types of black holes. They may release intense gamma-ray bursts, devour neighboring stars, and stimulate or hinder the birth of new stars depending on where they are located. Recent findings provide fascinating evidence that black holes can profoundly impact the areas around them. The resulting heated and accelerated matter attracts matter by radiating x-rays into space as it accelerates and warms up. In this situation, when the star is being drawn toward the black hole, it may rip apart. A black hole will accrete matter, or pull it inward, for instance, if it passes through a cloud of interstellar matter.Ī regular star may experience similar behavior as it approaches a black hole. But, by observing how they affect nearby matter, we may deduce the existence of black holes and study them. These equations demonstrate that if the star's mass is greater than roughly three times that of the Sun, the force of gravity will outweigh all other forces and create a black hole.īlack holes are invisible to telescopes looking for light, x-rays, or other types of electromagnetic radiation - for the very reasons explained above. This is where they get their name.Įinstein's theory of general relativity, which demonstrates that when a big star of a certain size dies, it leaves behind a small, dense remnant core, is most famous for theorizing about the existence of black holes. For example, as a result, it generates a gravitational force that is so powerful that even light cannot escape.įor a long time, physicists had speculated about the possibility of an object in space so dense that not even light could not escape. For a typical black hole, imagine a star 10 times as massive as our Sun being crammed into a sphere the size of New York City! That is a lot of stuff in a relatively small "container".Ĭompressing this much mass into a small space significantly impacts the surrounding stuff around it. Instead, black holes are a lot of matter crammed into a very tiny space.
