The magnificent life of a black hole. The black hole is a mystery that you will want to learn about. A black hole does many wonderful things in outer space. Black holes in outer space have been a mystery for years. There are many questions such as how is a black hole born and how does a black hole grow. What is a black hole? A black hole is a dead star in outer space. It is where planets and stars disappear at. The gravity of a black hole is way too strong ( Aguilar 39). The black hole is a weird object in outer space and a black hole is formed when two giant stars or more collapse together and basically vacuum anything that comes near it ( Aguilar 39). It might be gases around the black hole. People call it a black hole because light can’t escape from it (Cool Cosmos). So the hole appears black and the volume of the black hole is zero (Cool Cosmos). The black hole may be dangerous the black holes are born from supernovas (Mack 31). You will not be able to see a black hole not even if you use a telescope because there is no light to see anything (Mack 31). They come in different sizes such as small, medium, and large (Mack 31). It is filled with a lot of material so they are squashed into an extremely small space that is what gives the hole super strong gravity. Since the light can’t escape from the black hole when the light is the speed of 186,000 miles then nothing that we know of can (Cool Cosmos). Black holes may be anywhere such as in the center of a milky way and the density is infinite or unlimited (Mack 32). A black hole can’t be measured because it has no region to measure but the black hole do rotate on an axis like the the earth and other planets (Mack 31). They use the name black hole because the objects look like bl... ... middle of paper ... ...ve to get to get close at all for a black hole to catch it so it can grow bigger and bigger and the more a black hole vacuums things the bigger they get (Science & Technology from the U). Stars, gas clouds, and any other materials are the black holes food basically they eat it the more they come near them (Science & Technology from the U). Black holes can be dangerous. They can be dangerous because they can suck anything up. There are large numbers of small stars being captured. They mostly grow from stars. The more they eat the bigger they get. This is how black holes grow (Science & Technology from the U). In conclusion, black holes can be dangerous. Black holes can grow very big. The bigger the black hole the more damage it may do. Black holes give off light at the very bottom of it. It gives off a very bight light. That’s why they call the bottom a black hole.
Starting with black holes, Khalili describes the creation of one. I found that a black hole is what remains when a massive star dies. Because stars are so massive and made out of gas, there is an intense gravitational field that is always trying to collapse the star. As the star dies, the nuclear fusion reactions stop because the fuel for these reactions gets burned up. At the same time, the star's gravity pulls material inward and compresses the core. As the core compresses, it heats up and eventually creates a supernova explosion in which the material and radiation blasts out into space. What remains is the highly compressed and extremely massive core. The core's gravity is so strong that even light cannot escape. This object is now a black hole and literally cannot be seen because of the absence of light. Because the core's gravity is so strong, the core sinks through the fabric of space-time, creating a hole in space-time. The core becomes the central part of the black hole called the singularity. The opening of the hole is called the event horizon. Khalili describes that there are two different kinds of black holes:
Within William Rowe’s Chapter two of “The Cosmological Argument”, Rowe reconstructs Samuel Clark's Cosmological Argument by making explicit the way in which the Principle of Sufficient Reason, or PSR, operates in the argument as well as providing contradictions of two important criticisms from Rowe’s argument.

The whole idea of time and black holes has been questioning scientist and many common people for decades. Whether or not the theories provided make it physically possible to allow us to ever use any type of a black hole to an advantage? Technology over these past years has allowed us to learn more and more about what black holes are and what they can do. While also allowing ourselves to discover new possibilities that they might bring forth to greater innovations in our near future. But we can only imagine, through our knowledge and technology, what a black hole could do for us, due to all the dangers they bring forth.
The responsibility of super massive black holes is to hold the galaxies together. (Millis 2014) Super massive black holes are very dense and its believed that their density can reach infinity in a way that even light can't pass through their gravitational force. (NRAO 2014)
A Black Hole is defined as an object in space that is so compact, that has a gravitational pull so powerful, not even light can escape its pull. In most cases Black Holes are formed when a massive star (much larger than our own) undergoes a supernova explosion. When this happens, the star may collapse on its own gravitational pull, thus resulting in a an object with infinitely large density and zero volume. As a result, the escape velocity (the speed required to escape the gravitational pull) becomes even greater than the speed of light, and because nothing can travel faster than the speed of light, nothing can escape a black hole.
Before I begin to speak about black holes, I will have to explain what the white glowing specks in the sky are. Without a star a black hole could not be formed. In the beginning of a star life a hydrogen is a major part of its development. Stars form from the condensation of clouds of gas that contain hydrogen. Then atoms of the cloud are pulled together by gravity. The energy produced from the cloud is so great when it first collides, that a nuclear reaction occurs. The gasses within the star starts to burn continuously. The hydrogen gas is usually the first type of gas consumed in a star and then other gas elements such as carbon, oxygen, and helium are consumed. This chain reaction of explosions fuels the star for millions or billions of years depending on the amount of gases there are.
The Main Strengths of the Cosmological Argument There are many strengths within the Cosmological Argument which have proven theories and ways to prove the existence of God. Many of these strengths have come from such scholars as; Copleston, Aquinas and Leibniz, all of which have put together major points to prove the existence of a non-contingent being. One of the main strengths of the Cosmological Argument is from Aquinas way I that was about motion. This would be a posteriori argument because you need to gather evidence from the world around you.
What is a brain aneurysm? One could define a brain aneurysm as bulging, weak area in the wall of an artery that supplies blood to the brain. Over time, weak areas in the walls bulge out causing the blood vessel walls to become weaker as the aneurysm grows (Simon). In most human beings, a brain aneurysm can go undetected for years even possibly ones entire life. Some people however are not so lucky, in some instances, the aneurysm can rupture or explode, causing a hemorrhagic stroke, which is known as the type of stroke that causes bleeding in the brain. It is a known fact that approximately 8% of all strokes occuring world wide, are caused from the rupturing of brain aneurysms. Those are the unlucky people, fortunately, about 94% of all brain aneurysms do not rupture at all, and people are able to live their lives normally, just of course being careful not to do anything to severely damage their head (Nisacara).
I believe that the meaning of life is to love and care for others despite their imperfections. It’s hard to imagine how God can love his children who are nothing but horrid, disgusting, and filthy. Everyone craves love, but even though, we chose not to give love. Romans 3:23: “For all have sinned and fall short in the glory of God.” I am sure that mostly everyone including myself has experienced the cold heartedness we possess when it comes to loving another person who is not perfect. Maybe it is your spouse who you are having a troublesome time loving, perhaps your own mother, a co-worker, your best friend or even your neighbor. The reason why it is hard for us to love imperfect people is because we ourselves are imperfect. Although some
A star begins as nothing more than a very light distribution of interstellar gases and dust particles over a distance of a few dozen lightyears. Although there is extremely low pressure existing between stars, this distribution of gas exists instead of a true vacuum. If the density of gas becomes larger than .1 particles per cubic centimeter, the interstellar gas grows unstable. Any small deviation in density, and because it is impossible to have a perfectly even distribution in these clouds this is something that will naturally occur, and the area begins to contract. This happens because between about .1 and 1 particles per cubic centimeter, pressure gains an inverse relationship with density. This causes internal pressure to decrease with increasing density, which because of the higher external pressure, causes the density to continue to increase. This causes the gas in the interstellar medium to spontaneously collect into denser clouds. The denser clouds will contain molecular hydrogen (H2) and interstellar dust particles including carbon compounds, silicates, and small impure ice crystals. Also, within these clouds, there are 2 types of zones. There are H I zones, which contain neutral hydrogen and often have a temperature around 100 Kelvin (K), and there are H II zones, which contain ionized hydrogen and have a temperature around 10,000 K. The ionized hydrogen absorbs ultraviolet light from it’s environment and retransmits it as visible and infrared light. These clouds, visible to the human eye, have been named nebulae. The density in these nebulae is usually about 10 atoms per cubic centimeter. In brighter nebulae, there exists densities of up to several thousand atoms per cubic centimete...

Stephen Hawking has been hailed as one of the most brilliant theoretical physicists since Albert Einstein. Hawking was born on January 8, 1942, which as he likes to point out is the 300th anniversary of Galileo's death. Hawking originally studied at Oxford University in England studying physics even though he would have preferred math. He moved onto Cambridge University to work on his PhD in cosmology. Hawking's career has focused upon the cosmic entities known as black holes, and has extended to specialized areas such as quantum gravity, particle physics, and supersymmetry.
Black holes are the result of the death of a massive star, leaving behind a dense remnant core that eventually collapses to create a gravitational force so strong that nothing, including light, can escape the force. The theory that black holes existed started back in the early 1900s and since then astronomers and scientists have been trying to get a better understanding of them. This phenomenon has been a working progress for astronomers and scientists for many years and as we develop a better understanding of our solar system, the more likely it is to make a significant discovery that can answer some of the most difficult questions about our incredible galaxy and solar system. The more information we are able to acquire about our universe, the more questions we might be able to answer about our existence. With advancements in technology we may be able to see some significant discoveries and insights into the world of black holes.
Astronomers believe that most galaxies consist of a supermassive black hole at the center, which attracts all constituents of galaxies such as, dust, gases (mainly Hydrogen and Helium), atoms, stars, interstellar clouds and planets to the center by force of gravity, but are not sure whether all galaxies contain a black hole in the center. Galaxies keep moving in relative motion to one another and intermittently can come so close that the force of gravitational attraction between the galaxies may become strong enough to cause a change in the shape of the galaxies, while in exceptional cases, the galaxies may collide. If two galaxies collide, they may pass right through without any effect or may merge, forming strands of stars, extending beyond 100,000 light years in space (World Book Online Reference Centre, 2005). Hence, neighboring and often other colliding galaxies induce the sha...
