Redd (2013) defined black holes as an area of space that has infinite density and very powerful force of gravity which pulls everything inside. Even light which is known with its rapidity can not get out from that force (p. 1). Due to the fact that is stated above, light is engulfed by black holes and that is the reason of why we can not see the black holes with unaided eyes (“What is Black Hole?”, 2008, para. 2-3). Even nobody can see the black holes with unaided eyes, there is no doubt about the existence of black holes by the help of observations made by space telescopes. As a result of all observations, scientists recognized that stars and gas behave extraordinary and create the high-energy light while rotating around the black holes and these are evidences of existence of the black holes (“What is Black Hole?”, 2008, para. 2-10). As mentioned before, black holes has infinite density, that phrase emphasizes that besides its extraordinary mass, the volume of black holes is approaching zero. Addition to that Redd (2013) compared the volumes of stars and the black holes and determined the volume of black holes are smaller than stars. Black holes are categorized according to their mass. Redd (2013) made an observation about the rate of existence in the universe for each type of black holes and emphasized the power of gravitational force . “Small black holes populate the universe, but their cousins, supermassive black holes, dominate. Supermassive black holes are millions or even billions of times as massive as the sun, but have a radius similar to that of Earth's closest star. Such black holes are thought to lie at the center of pretty much every galaxy, including the Milky Way.” (Redd, 2013, p. 2). Despite the constantly improving research data, scientists still don't know everything about black holes. In fact, Cain (2008) stated that, there is a theory

    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:

    To first understand a black hole, you must understand how it is created. Most black holes are produced by dying stars that have a mass twenty times greater than our sun. A star eventually becomes a black hole because the energy and pressure pushing outward is overcome by gravity that pushes inward. For big stars the gravity force causes a star to collapse under its own weight. The star then will explode as a supernova and some outer parts of the star are sent out into space. The core is still intact, and if it has collapsed under its own weight, it will have formed a star. This core is said to have nearly zero volume, but with infinite density, known as a singularity.

    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 idea of Black Holes was first proposed in the 1700s by scientists John Michell and Pierre-Simon Laplace, who argued, independant of each other, that there might be objects in the universe with such a large gravitational force, that even light could be trapped. Published in 1916 Einstein’s theory of general relativity which included how gravity does affect light’s motion, gave way to scientific discoveries involving black holes. In Einstein’s own theory, he was only able to approximate the solutions to some of his own equations, however Karl Schwarzschild was able to provide the solutions. These solutions described objects like black holes that had such massive density that nothing could escape them. Schwarzschild theorized that if an object had such a small radius, that the escape velocity will be greater than the speed of light. Because as previously mentioned, nothing is faster than the speed of light, the object would be sucked into itself by it’s own gravitational pull, which would cause the object to disappear.

    Such prospects are intriguing, and provide science fiction novelists with endless material for their writings. None of these theories have been proved, and since we can't get close enough to a black hole to study one, they're all perfectly valid. Perhaps one day mankind will discover the truths behind black holes.

    Black holes are points in space where there are extreme gravitational pulls that prevent anything, including light, from escaping. The reason for such a strong gravitational pull is due to vast amounts of matter being contained in a small amount of space. Stellar black holes form from stars with a mass greater than 20 solar masses and can be a result of gravitational collapse. Gravitational collapse is a result of the star’s internal pressure not being able to resist the stars own gravity. When the star is exhausted of its nuclear fuel such that it cannot maintain a high enough temperature it will begin to collapse under its own weight (Seidel 2011). As the star collapses it causes a supernova which blasts the outer layers of the star into space while the core completely collapses under its own weight. If the remnant core left behind exceeds 3 solar masses there are no known forces that can prevent the core from completely collapsing into a black hole (p. 568 Bennett et al. 2013)

    The American scientist John Wheeler coined the phrase “black hole” in 1969 to describe a massively compact star with such a strong gravitational field that light cannot escape. When a star’s central reserve of hydrogen is depleted, the star begins to die. Gravity causes the center to contract to higher and higher temperatures, while the outer regions swell up, and the star becomes a red giant. The star then evolves into a white dwarf, where most of its matter is compressed into a sphere roughly the size of Earth. Some stars continue to evolve, and their centers contract to even higher densities and temperatures until their nuclear reserves are exhausted and only their gravitational energy remain. The core then rushes inward while the mantle explodes outward, creating neutron stars in the form of rapidly rotating pulsars. Imploding stars overwhelmed by gravity form black holes, where the core hits infinite density and becomes a singularity (some estimate it at 10^94 times the density of water).

    Black holes were predicted by Einstein's theory of general relativity. According to Space.com “In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity. It introduced a new framework for all of physics and proposed new concepts of space and time. Einstein then spent ten years trying to include acceleration in the theory and published his theory of general relativity in 1915. In it, he determined that massive objects cause a distortion in space-time, which is felt as gravity.”

    Despite all our advances in particle physics and astrophysics, we still don't know what form of matter makes up 95% of the universe. Physicists have named this mysterious substance dark matter, for it can not be detected by observation (it does not emit visible or other frequency light waves). However, we know that dark matter must exist, following Newton's universal law of gravity.

    Black holes were originally thought to have only mere mathematical concepts. There was seemingly no possible way to compress any object into a space small enough to equal to its schwarzschild radius. Later however, astronomer Subrahmanyan Chandrasekhar calculated that stars much larger than our own sun should theoretically be able to collapse into a black hole (UTFC). A star is like a blown up balloon with the force of gravity trying to compress the balloon inwards and the air trying to push the balloon outwards. Likewise, stars are held in balance by gravity trying to collapse the star inwards going against the outwards pressure of the internal reactions of the star called nuclear fusion.

    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.
