Recommended: Key to understanding black holes
Like the boundaries on earth, mankind has always looked to the sky in awe for it seemed boundless in its ever growing horizon. Out of all the cosmos that’s being found and discovered every day, there is one object that stands to elude scientists still, the black hole. Albert Einstein, and all the brilliant scientists after his, help to design and create a part of the universe that’s very crucial to understanding existence. The perimeters of a black hole have been a great this that has been discussed and observed to the point where it eventually becomes clear as its compared to objects around or like it. The physics of the black holes existence is still unclear for it shows properties that support Einstein’s theory and quantum mechanics, but at the same time breaks them both.
In 1915, albert Einstein had proposed his theory of general relativity at the Prussian Academy of Sciences in Berlin. It took him three years to finally make the equations for his theories, but he still need to go in to the field and test it. To do so, he required a total solar eclipse, were the suns pull on space-time would still be affective but its luminosity wouldn’t block the light of the stars behind it. Sir Arthur Eddington, English astronomer and supporter of general relativity, had led an exploration to the Principe Island just off of West Africa. Tis easy to predict when the solar eclipse will happen, the problem is making sure you’re in the right place and time, and that the weather is in your favor. On May 29, 1919 was the day the eclipse was set to happen, so from there the team set up there equipment and hoped for the best. Just as the moon started to hit the suns edge, the clouds began to thicken, but right before totality there was a break. Si...

The origins of the super-massive black holes which concludes how they were formed and what caused them to form is an unsolved problem which is yet a mystery of astrophysics. ( Millis 2014)
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 - the strange scientific phenomenon that has astounded physicists and astronomers alike for decades. Popular subjects in science fiction novels, black holes are one of the greatest enigmas of the scientific world. Even today, the concept of a super-dense ball of matter that not even light can escape from is somewhat farfetched, and many scientists disagree with each other about nearly every aspect of a black hole. This project will attempt to shed some light on these mysterious formations, and will inform you the reader of the most popular and widely accepted theories surrounding them.
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. What r...
Just recently a major discovery was found with the help of a device known as The Hubble Telescope. This telescope has just recently found what many astronomers believe to be a black hole, After being focuses on a star orbiting empty space. Several pictures of various radiation fluctuations and other diverse types of readings that could be read from that area which the black hole is suspected to be in.

Nightfall can be considered one of the best sf short stories of all times, because of the writer’s ability to integrate theories, events, and beliefs of others, into a captivating fictional story. In that, Isaac Asimov, cleverly combined, one might say, “past, current, and future events into his storyline.” He included theories of gravitation, events predicted by those called, “Cultist,” in his story, and various beliefs of the different characters. Wikipedia states “Aton, one of the characters in the story, who formulated the Theory of Universal Gravitation, in-story discussion of this makes light of an article once written about Einstein's theory of relativity, referencing the false notion that "only twelve men" could understand it.”
A hundred years ago, a young married couple sat at a kitchen table talking over the items of the day while their young boy sat listening earnestly. He had heard the debate every night, and while there were no raised voices, their discussion was intense. It was a subject about which his parents were most passionate - the electrodynamics of moving bodies in the universe. The couple were of equal intelligence and fortitude, working together on a theory that few people can comprehend even to this day. Mileva Maric Einstein was considered to be the intellectual equal of her husband Albert, but somehow went unrecognized for her contributions to the 1905 Papers, which included the Special Theory of Relativity. The stronger force of these two bodies would be propelled into the archives of scientific history, while the other would be left to die alone, virtually unknown. Mrs. Einstein was robbed. She deserved to be recognized for at least a collaborative effort, but it was not to be. The role which society had accorded her and plain, bad luck would prove to be responsible for the life of this great mathematician and scientist, gone unnoticed.

A Solar Eclipse occurs when the moon crosses between the Sun and the Earth in a way in which the moon casts a shadow onto the Earth. This phenomenon has been occurring for as long as we can tell, and has been observed as early as 3340 BCE. Many civilizations have come and gone, studying these eclipses, trying to predict them, and even building their own lore around them. Each of these civilizations came up with different ways to predict the next eclipse. Some were able to successfully predict them, but few were able to do so consistently.

Einstein himself, working at Princeton with Nathan Rosen had discovered that the equations of relativity actually represent a black hole as a bridge between two regions of flat space-time, a phenomenon known as the “Einstein-Rosen Bridge”. Later on, in 1963, the New Zealand mathematician Roy Kerr found that if a black hole is rotating, a singularity still forms, but in the form of a ring, not a point. It was believed that in principle, a particle may be able to fall towards the singularity, but if at some point moved through the hole instead of the ring, the particle may not be lost forever. Therefore, with these theories in mind, a particle falling into a black hole will fall through the ring that the singularity has become, then going through the Einstein-Rosen Bridge, eventually being spewed out of the white hole into another space-time continuum.
In 1905, Albert Einstein wrote his paper on the special theory of relativity (Prosper). This theory has the reputation as being so exotic that few people can understand it. On the contrary, special relativity is simply a system of kinematics and dynamics, based on a set of postulates that is different from those of classical mec...
Evidence that the heavens house a previously unknown type of black hole was reported by scientists yesterday. Data from NASA’s Chandra X-Ray Observatory revealed a hole was some 600 light-years from the center of the starburst galaxy M82. The brightness of the x-ray source indicates that this moon-size hole has the mass of at least 500 suns, making it intermediate between stellar black holes and the supermassive black holes found at the centers of galaxies. “This opens a whole new field of research,” said Martin Ward, a lead author on one of three papers to be published on the subject. “No one was sure that such black holes existed, especially outside the centers of galaxies.”
