Their masses range from five (5) to a hundred (100) solar masses and can be observed as either a gamma ray burst or a hypernova explosion. The third type, known as the stellar black hole or stellar mass black hole is formed when a massive star collapses. Although the existence of intermediate mass black holes has still yet to be proven, there is indirect evidence that they exist using various positions from known stars. The second type is the intermediate mass black hole which is a hypothetical class with a mass ranging from a hundred (100) to a million (1000000) solar masses. In our solar system, the SMBH is located at Sagittarius A*. This is usually found at the center of the largest galaxies in space. This is the largest type amounting to an unmeasurable amount of solar masses. The first is the supermassive black hole or SMBH. Types of Black Holesīlack holes are categorized into four (4) types. This is done by considering the orbit of these stars since black holes causes major changes in a stars orbit. The presence of stars can also aide in the identification of the location and size of a black hole. These disks are heated by friction and can brighten immensely. Accretion disks are usually formed when a black hole absorbs matter. Most black holes are discovered using their interaction with the electromagnetic radiation and matter in its vicinity. READ: Kinetic and Potential Energy: Examples and Differences Between Both of Them Scientists hypothesize that at the center of any galaxy is a supermassive black hole. Once a black hole forms, it continuously grows by absorbing all the mass from its vicinity and at certain times, can even merge with other black holes. The special tools can see how stars that are very close to black holes act differently than other stars.”īlack holes form when immensely massive stars suddenly collapse or dies. Space telescopes with special tools can help find black holes. Because no light can get out, people can’t see black holes. The gravity is so strong because matter has been squeezed into a tiny space. “A black hole is a place in space where gravity pulls so much that even light can not get out. Throughout the scientific community, black holes were always considered a mathematical mystery until 1960 when it neutron stars were discovered. It was Karl Schwarzschild who provided the first solution of general relativity that characterized black holes in the year 1916. Pierre-SImon Laplace and John Michell were the first ones to consider objects with strong gravitational fields that could trap light. This is defined as a black body with a temperature inversely proportional to its own mass. In addition, the quantum field theory predicts that black holes also emit a type of radiation called the Hawking Radiation. The tiny space is the event horizon, which is the boundary from where any form of matter becomes trapped. In Einstein’s general theory of relativity, he states that black holes compresses all types of mass into a tiny space. This includes all types of particles and even all forms of electromagnetic radiation. This is because a system at zero temperature exists in its ground state.Simply stated, a black hole is a place where the pull of gravity is so immense that not even light can escape. In 1973 Bekenstein suggested ln 2 0.8 π ≈ 0.276 cannot go to zero is analogous to the third law of thermodynamics, which states that the entropy of a system at absolute zero is a well defined constant. In 1972, Jacob Bekenstein conjectured that black holes should have an entropy, where by the same year, he proposed no-hair theorems. The increase of the entropy of the black hole more than compensates for the decrease of the entropy carried by the object that was swallowed. If black holes carried no entropy, it would be possible to violate the second law by throwing mass into the black hole. The second law of thermodynamics requires that black holes have entropy. 3 Quantum gravitational corrections to the entropy.
