Black Holes Research Papers

Gravity. We all know what it is, and we take that for granted. But, as all great discoveries, there was a time before “gravity”. Of course, it existed, just people didn't really know about it, or how it worked. That is, until the year 1687, when Isaac Newton came about. But first, let's back up.

​Black holes are associated with the destruction or dying of relatively large stars. Black holes do not happen every time such stars are collapsed. The collapsing of stars mostly result in

Gravity is the force which attracts an object to the center of the earth, and toward any other physical object having mass. Issac Newton and Albert Einstein both contributed to today's knowledge of gravity.Newton started working in 1687 by scratch, he knew nothing about gravity it until he saw an apple fall. Newton dint have much friends growing up because he would lock himself in his room and brainstorming ideas about how gravity could work. A few decades later Einstein started brainstorming off Newtons work to get an even better understanding of it.

Of course, as intriguing as a black hole’s effects within in and around galaxies could be, we must also keep in mind that some theorists believe black holes are responsible for producing, Dark Matter. As stated by the “The Gale Encyclopedia of Science”, in their article, “Dark matter”, Dark matter is, “material that does not emit or reflect light and that is therefore invisible” (The Gale Encyclopedia of Science). Scientists believe dark matter and black holes are in relation, because recent studies done by Russian astrophysicists Vyacheslav Dokuchaev and Yury Eroshenko, institute that, “dark matter could be made of microscopic — or quantum — black hole atoms (Dokuchaev, Eroshenko). In a sense, making it dark, however, as reported by the “World of Scientific Discovery”, in their article, “Dark matter”, “dark matter does not behave like ordinary matter, such as dust or gas, which leaves traces by emitting, deflecting, or absorbing electromagnetic radiation” (World of Scientific

We know of many stars that exist, but the main stars are White dwarfs, Pulsars, Neutron stars, Magnetars, Brown dwarfs, Black Holes, Cepheid Variable stars, Supergiants, Red Giants, Novas, and Quasars. Starting with White Dwarf, this star is usually the size of a planet and is last stage of a stars life, when it loses all its layers from the planetary nebula. This star is very dense and especially hot after it disables its nuclear fuel. It starts to cool done over the next billions of years. Pulsars, this star is practically a white dwarf star, but has electromagic ration beaming out of it. There are two steady lights (electromagic ration) that point in two opposite directions. It always seems to be blinking, but this is just from the motion

Active Galactic Nuclei (AGNs) are very luminous and dense regions in the center of galaxies believed to host Super Massive Black Holes (SMBHs). The electromagnetic radiation sent out from AGNs is conjectured to come from matter that the SMBHs accrete which then takes the form of an accretion disk circling the black hole. These accretion disks are best approximated with an irregular density and temperature distribution made up by very hot gas and plasma~\citep{skadowski2015global}.

A little more in depth: Black holes are the remnant of stars that have gone supernova and collapsed upon themselves. When the star explodes in a supernova, not only does it explode outwards but it pushes inwards on its own core as well. The pressure placed on the core causes it to implode upon itself, and that's where the black hole is formed. However, black holes are only formed by stars large enough to create one... for instance the sun, everyone's favorite star, will likely not become a black hole once it goes nova. A star 10 times the size of our sun probably will, depending on how much matter is lost in the supernova. Only those huge stars have enough gravity to create a black hole.

Normal stars (like the Sun) shine because there is nuclear fusion inside them, hydrogen nuclei fuse together to form helium nuclei, helium nuclei fuse together to form carbon nuclei, and so on. Nuclear fusion generates heat and light which make the stars shine. Also, this heat provides outwards pressure which balances the inward gravitational pull, making the star stable. This inward gravitational pull exist for every object - you, me, the earth, the sun, other stars, etc. Every atom of an object experiences gravitational pull towards its centre due to its own mass. But for small objects like the earth, this inward gravitational pull is negligibly small, but not for the stars. Remember the Sun is 333054 times heavier than the earth, and it is one of the

As more material is pulled into a black hole, it grows bigger and its gravity strengthens (Sipiera 29). Also, a black hole’s gravitational pull is so strong that light can even be pulled into the hole (Jefferis 4). Next, black holes are the last step of the life of a star. Although a black hole’s gravity is strong, only a small part of space will be swallowed. Because black holes are able to pull light into themselves, they cannot be seen. These are a few of the facts that scientists have uncovered.

Yesterday, NASA released news that will help us understand the formation of oval galaxies, specifically, the new data answered some old questions about why oval galaxies take so long to form. It turns out that the way a black hole controls the proto-matter of a baby galaxy actually regulates star birth as the galaxy takes shape around it.

First the mystery of the black holes and how they were created goes way back to when astronomers first discovered them. The astronaut said “he saw a blob of black matter and black holes are made when a star burns out or explodes but the astronaut never truly saw the actual thing. Black holes absorb light particles that are close enough to it so that it can thrive and continue. When a black hole goes away the light that it absorbed is turned into a new star. When an astronomer found a black sphere shaped cloud of matter in space he didn't really see it but he saw it pulling in large amounts of light that have been destroyed from an exploded star. If anything but light matter happens to get into a black hole it would just go through it rather

Black Holes are formed when massive stars, about 20 times the mass of our sun run out of fuel and nuclear fusion cannot take place. The gravity cause the star to collapse into itself and explode releasing a lot of gas and particles out into space. When stars explode this way, it’s called a supernova. In younger stars the nuclear fusion opposes the force of gravity which keeps the star stable. However now that there isn't any force to oppose the gravity, it keeps collapsing inwards until eventually all the mass gets concentrated to a single point. This single point is called

Black holes are celestial bodies so dense and strong that nothing can escape their pull. The idea of black holes is generally referred to the French mathematician, Pierre Simon Laplace. In 1796, Laplace who was studying the subject of escape velocity; this is the speed that something must be accelerated to in order to prevent being pulled back by the gravity of a larger body. For example, to escape the Earth’s gravitational pull we must accelerate our rockets to over 11 kilometers per second. If the rocket travels any slower then it will fall into a victim of earth gravity. If it travels any faster it will never return. When Laplace worked on this problem he noticed a relationship between the size of the object and its mass. Laplace noticed

This may help us understand where all the material that is sucked into a black hole ends up as, but it is just an untested theory. We can measure dark energy by using a specially made camera that “...has 74 CCD's(Charge-Coupled Device;used for electric charge movement) that are each 3 by 6 centimeters across and can detect five hundred megapixels in total.”(“Essay: Will Dark Energy Please Come to Light?”2016). When it was mounted on a telescope in Chile in 2011, the camera looked for evidence of dark energy.With the help of the Hubble Telescope, the camera proved the existence of dark

There are two types of black holes that exist in our universe. The first one being the Schwarzschild black hole which happens to be the simplest one of the two. This black hole is considered the simplest because its core does not rotate which means the black hole is completely stable at all times of the day. The next black hole is the Kerr black hole, which happens to be the most common in nature. This black hole in contrast to the Schwarzschild black hole does indeed rotate. When the rotating star dies out and collapses, the core continues to rotate and therefore, that carries over to the black hole. Scientists believe that the smallest black holes formed when the actual universe formed and began. They also have been led to believe that the supermassive black holes that exist in our universe were made at the same time as the galaxy that they
