Einstein’s Theory of General Relativity originally came to him in 1907 while he was sitting in a chair in the patent office in Bern. Lost in thought, he began wondering what it would be like to drop a ball while falling off the side of a building (James Overdunn, Stanford Edu) Granting all this, he realized that the person who was falling would not be able to detect the effect of gravity on the ball whereas an observer could. Hence, he figured out the principle of Equivalence, that gravity pulling in one direction is completely equivalent to the acceleration in the opposite direction. Nevertheless, his work was only seen 8 years later when he published his theory in 1915.
Another key factor in Einstein’s theory of general relativity is that there is a “space-time”. Space-time is made up of four dimensions, three of the dimensions are made up of space and the 4th dimension is made up of time. He found that space-time is the same for everyone, but that at the higher altitudes time would actually go faster and at a lower altitude time goes slower. Another thing that he realized concerning space-time is that it is curved by matter that we see as gravity and that the denser an object is in space the more it distorts the space-time around it. Meaning that our sun will distort the space around it more than our planet or the moon does. This distortion is like a curvature, much like what happens around your feet when you stand on a trampoline. Now near a black hole, per Einstein’s theory, we have found that space-time is so curved that after an object passes through what we call “The Event Horizon” also known as the point of no return that the escape velocity will become so high that nothing can leave it.

Conclusion
Einstein’s theories of Special and General relativity have helped shaped the world that we live in today. By helping us not only know more about space but about the world around us. It helped us understand the laws of nature are the same for everybody and that the speed of light is the same for everybody also. It helped us understand more about space with his theories on space-time and the curvature of space-time. His theories have led to many discoveries that help us in our everyday life such as nuclear technology that we use for our power and medical field.
Since his birth, Albert Einstein has had the most beneficial effects on the events of the world. Albert Einstein was born in Ulm, Germany on March 14, 1979 and as a boy displayed an unquenchable curiosity for understanding science and all of its mysteries. As Albert Einstein’s life progressed, he found himself working as a patent clerk in Bern. While working as a patent clerk in Bern, Albert Einstein had a plethora amount of time which was devoted to formulating his theories. Also during this time, Albert Einstein received his Doctorate degree and started working on one of his most influential papers, which was the Special Theory of Relativity. After Einstein completed his Special Theory of Relativity, he moved onto creating the General Theory of Relativity which earned him the Nobel Prize in Physics in 1921. With the creation of both the General Theory of Relativity and the Special Theory of Relativity, Einstein was able to create his Theory of Relativity which comprises of both theories. Other scientific discoveries that Einstein made are the existence of the photon, the theory of Brownian motion, the concept of Mass-energy equivalence, the photoelectric effect, the first quantum theory of specific heats, the Einstein-Brilloui-Keller method for finding the quantum mechanical version of a classical system , Bose-Einstein statistics and Bose-Einstein condensates, the EPR paradox, and although his efforts were unsuccessful, in his last thirty years of life Einstein explored various classical unified field theories that could account for both electromagnetism and gravitation and possibly quantum mechanics.
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...
...ke for instance the two images below. The first is a two-dimensional representation of the gravity of a normal star. Imagine any object floating through space as a marble. Said marble rolling along the flat surface of the space will roll into the indentation made by the sun's gravity. If you flick the marble hard enough, it can roll out of the indentation and roll away. The second pic is a representation of the gravity made by a black hole. Notice that if the marble rolls into the hole, there's no way it can get out, since there is no end to the hole.
The theory of relativity is the basic theory about space-time continuum and gravitation which was mainly established by the greatest theoretical physicist Albert Einstein. According to the areas it aims to describe, Einstein’s theory of relativity can be classified into special relativity (space-time) and general relativity (gravitation) 1. The theory of relativity, as do quantum mechanics, brought a revolutionary impact on the foundation of modern physics, and thus had an impact on modern technology. And it impacted the “common sense” understanding that people had of the universe by its new concepts such as four dimensional spaces and curved space.
John Michell and Pierre de Laplace, in 1783, showed that when the escape speed from the surface of a body equals the speed of light, Newtonian theory breaks down. According to general relativity, spacetime is curved and the curvature is a measure of the strength of gravity. Thus as a star contracts, its surface gravity increases and spacetime becomes more curved. At the Schwartzschild radius (Rs=2GM/c^2) spacetime is so curved that the body is enclosed, becoming a black hole wrapped in curved spacetime where not even light can escape it. Also, as a mass contracts, its surface gravity increases in strength and light rays emitted from the surface are increasingly redshifted and deflected (gravitational redshift=(l...
"The release of atomic energy has so changed everything that our former ways of thinking have been rendered obsolete. We therefore face catastrophe unheard of in former times. If mankind is to survive, then we need a completely new way of thinking."
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.”
What was General Relativity? Einstein's earlier theory of time and space, Special Relativity, proposed that distance and time are not absolute. The ticking rate of a clock depends on the motion of the observer of that clock; likewise for the length of a "yard stick." Published in 1915, General Relativity proposed that gravity, as well as motion, can affect the intervals of time and of space.
The Theory of Relativity, proposed by the Jewish physicist Albert Einstein (1879-1955) in the early part of the 20th century, is one of the most significant scientific advances of our time. Although the concept of relativity was not introduced by Einstein, his major contribution was the recognition that the speed of light in a vacuum is constant and an absolute physical boundary for motion. This does not have a major impact on a person's day-to-day life since we travel at speeds much slower than light speed. For objects travelling near light speed, however, the theory of relativity states that objects will move slower and shorten in length from the point of view of an observer on Earth. Einstein also
Many scholars, researchers, and scientist claim that the greatest discovery in mankind’s history was actually made by Professor Albert Einstein and is called the “Theory of Relativity.” The reason they say this is that by being able to explain and understand how everything relates to everything else is the key to advancing or evolving our knowledge about everything. In other words if we know how a starfish relates to a star, in theory we can know or cause to be known everything in-between. So the very evolution of knowledge is at stake, never mind the methodology that is used.
In the early 1900’s, scientists learned that they had the ability to produce nuclear energy (Anderson 4). Though, throughout the early 1900’s how to produce this energy was still puzzling to most scientists. Leo Szilard, a Jewish man fleeing from Germany in 1933 figured out that colliding a neutron with a nucleus would start the chain reaction needed to produce massive amounts of energy. Then, this energy could be channeled into a weapon that could wipe out an entire city. Szilard was afraid that his new nuclear research might get into the wrong hands. Eventually, he turned to another German scientist that was known around the world, Albert Einstein. Einstein agreed that this research in the grasp of Germany could mean the end of days. Finally, they decided it was best to give it to a strong ally power, the United States (Anderson 12-17).
the outer part of it called space time curvature which is the beginning part of when the time in space starts differing. For example let's say a kid named timmy was thrown into a black hole, but let's pretend he is not dead yet. Then their is johnny who is outside of the black hole and watching timmy slowly die. The time difference would be morphed. Johnny would see that timmy’s time is slower than his, while johnny’s time would be accelerating in timmy’s view and this is only because of the fact timmy is in a black hole.

Initially, Albert Einstein was the person to predict the existence of black holes through his General Theory of Relativity, in which he had created several general equations that show the interaction of gravitation as a result of space being curved by matter or energy. In 1915, he published Einstein’s field equations, which specify how the geometry of space and time is influenced by whatever matter and radiation are present, and form the core of Einstein's general theory of relativity (Redd). The general theory relativity was the initial step in the process to finding out more information about black holes. As time went on, there were a few main contributors that solved these equations to help develop better theories on black holes. One of the most important contributors to the development of a better u...
