![]() Some scientists believe that intermediate black holes form from a merging of miniature black holes. This type of black hole would have several hundred of thousands of solar masses, rather than millions, or even billions of solar masses, like their larger cousins. Like miniature black holes, intermediate black holes are only really theoretical. These tiny black holes are, to date, purely theoretical, and it is theorized that most of them may have already evaporated. These tiny black holes are thought to have masses of hundreds of solar masses or less. To date, scientists have managed to define at least four different kinds of black holes:Ĭurrent theories suggest that small, or miniature, black holes (some as small as an atom) probably formed in the earliest moments of the universe. How black holes form depends on their type and origin. Source: Kristof Wesely/Wikimedia Commons How are black holes made of, and what different kinds of them are there? Black holes can, however, be "seen" with some special analysis of data collected from a wide range of telescopes (more on this later). The gravity is so strong because matter has been squeezed into a tiny space."Īs light is unable to escape the black hole's gravity, it appears completely black - hence the name. What is the definition of a black hole?īlack holes can be defined, according to NASA, as " a place in space where gravity pulls so much that even light cannot get out. Let's see what, if anything, they've managed to learn about the "Great Devourers" of the cosmos. These are just some of the "big picture" questions some of the greatest minds of astrophysics have mulled over for many decades.
