Introduction
Black holes are incredible processes that happen in space that are capable of crushing anything unlucky enough cross paths with them. Black holes have caught the attention of millions of people around the world because of their incredible strength and the fact that so much is unknown about them. The theories of possible outcomes resulting in traveling into a black hole has been used in many science fiction stories, but what we think is science fiction could actually exist. With black holes being out of our reach, and even difficult for our greatest minds to understand, what happens within them may just stay science fiction. The more we learn about black holes the more questions we ask.
Wormholes are another spectacle of the universe that are thought to be found within black holes, but they are merely a theory and may or may not exist. Wormholes could be the way we could finally achieve many things that have been highly sought out for years. One of the many advances that could come from wormholes is that they have the potential of us finally being able to accomplish time travel, leaving us to wonder what we could do if wormholes truly exist. Black holes and wormholes are surrounded by mystery, but what are they really capable of? They are but one of the many

The birth and structure of black holes
Because one of the requirements for a black hole is a dense mass, it is only natural that they come from the death of a star. Stars go through a process called nuclear fusion that is what causes energy to be produced which results in light. The process of nuclear fusion uses hydrogen as fuel to keep the stars f...

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:

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)

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.

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...
