According to the theory of relativity, nothing can travel faster than the speed of light. There would be a region from which it would be impossible for anything to escape. This region is called a black hole. This paper will discuss the creation and discovery of black holes and many other questions about the inescapable black hole.
Pierre Simon first thought of black holes back in 1796. His initial findings were based on the now discredited theory of Newtonian gravity. Simon was still able to realize that light could not escape from the surface of a sufficiently massive body. Unfortunately, in Simon's time, there was no way to test his idea. This idea was not actually determined until 1939, when J. Robert Oppenheimer and his student, Hartland Snyder, showed that a cold and sufficiently massive star must collapse indefinitely, becoming a black hole. Oppenheimer and Snyder could have never figured this out without the earlier work of Einstein and his general theory of relativity, which states that nothing can travel at the speed of light or faster.
Further studies were taken by a German astronomer, Karl Schwarzchild. Using Einstein's equations as a guide, he found that the effects of relativity begin to soar until space curvature closes in on itself and light waves become infinitely long. Such a region would be completely cut off from the outside. His surprising discovery was that these effects occur before one reaches the hypothetical focus of gravitational attraction. If a mass comparable to that of the earth were concentrated into a point, the radius at which these effects occurred would be roughly one centimeter. This became known as the.

gravitational radius or the Schwarzchild radius. It is ultimately recognized that the .
Schwarzchild radius was the gate to the black hole.
So, what exactly is a black hole? A black hole is a region of space-time in which the gravitational field is so strong that any light or other signal is dragged into the region and cannot escape to the outside world.
A black hole is a place where the curvature is so strong that a black hole is formed. ... A typical mass for such a black hole would be about 10 times the mass of the Sun, or about 10^{31} kilograms. The black hole's is surrounded by the event horizon whose size depends on the mass of the black hole. ... Works Cited "Black Holes." ... "Black Holes." ...
Most Physicists like to tell us that black holes are bald or that they have no hair. Upon translation what they mean is, if we were able to observe black holes each one would look exactly the same: pitch black as can be, and in the shape of flawless spheres. ... Unlike the colossal black holes that already exist, the donut-holes made by humans would not be much bigger than the nucleus of a single atom. ... An ant walking from A to B in this diagram would take approximately 10 seconds. ... At the point of maximum oscillation the black hole will become highly unstable and dangerous. ...
That mystery happens to be that of the ever elusive, black hole. ... The black hole's surface is known as the event horizon. ... A spherically symmetric black hole with a point electric charge has the same essential features as a rotating black hole. ... In order to understand what exactly a black hole is, we must first take a look at the basis for the cause of a black hole. ... Such spinning black holes are known as Kerr black holes. ...

There are two types of black holes, one being the stellar mass black holes "Which means that their mass is comparable to that of a star " and supermassive black holes (SMBH's), which "Are millions or billions of times the Sun's mass and are way to massive to have formed in the explosion of a single star"" (e.g. ... Also the size of the black holes event horizon can be calculated using Schwarzschild radius. The size (radius) of the black hole=mass of the black hole X (2G(gravitational constant)/ c^2(speed of light)). ... Black holes consume all matter around them including light. ....
Black holes have been said to be the key to traveling into the past. A black hole is a star that is sufficiently massive and compact creating a strong gravitational field that even light could not escape. ... (Hawking pg. 94) Black holes gravitational force is said to be great that it even pulls time inward, slowing time on the other side. There is a problem when traveling into a black hole. ... (Gribbin pg. 15) There is a process that might be able to work in stabilizing a black hole. ...
At this point in time, astronomists have yet to actually see a black hole. So how do they know that black holes do in fact exist? ... Scientists today call such an object a black hole. ... Since a black hole is a region of space from which nothing can escape, the time-reversed version of a black hole is a region of space into which nothing can fall. In fact, just as a black hole can only suck things in, a white hole can only spit things out. ...
Astronomers believe that Machos are made up primarily of red dwarf stars and black holes. ... Black Holes on the other hand have an over abundance of matter. ... Since the black hole is so dense, nothing that comes close to it can escape it's immense gravitational field, including light. For this reason, Black Holes are truly black. ... It occurs when a red dwarf or black hole passes between a star or galaxy and an observer on Earth. ...
