Astronomy

Within our universe there are millions upon millions of galaxies. Humans have known the existence of stars since they have had eyes. The mystery does not lie within what we can see, but what we cannot see. The theory that black holes have existed is not new at all.

All black holes are formed from the gravitational collapse of a star, usually having a great, massive, core. A star is created when huge, gigantic, gas clouds bind together due to attractive forces and form a hot core, combined from all the energy of the two gas clouds. This energy produced is so great when it first collides, that a nuclear reaction occurs and the gases within the star start to burn continuously. The hydrogen gas is usually the first time of gas consumed in a star and then other gas elements such as carbon, oxygen, and helium are consumed. This chain reaction fuels the star for millions or billions of years depending upon the amount of gases there are. The star manages to avoid collapsing at this point because of the equilibrium achieved by it. The gravitational pull from the core of the star is equal to the gravitational pull of the gases forming a type of orbit; however, when this equality is broken the star can go into several different


Physicists have speculated the existence of wormholes since the 1930's. These are gateways between different parts of the universe. A wormhole is made by linking a pair of black holes together. By doing this, a tunnel is created through time and space. If you traveled through one end, and exited out the other, you would be in a different time and place. The only difficulty in this is trying to keep the wormhole from closing while the traveler goes through. If it were to close, the traveler would not be able to survive to make it to the other end. Also, scientists have thought that it would be physically impossible to travel through the wormhole. One way it could be done is to use some sort of material that is capable of withstanding the great forces present.

stages. Usually if the star is small in mass, most of the gases will be consumed while some of it escapes. If the star was to have a larger mass however, then it may possibly Supernova, meaning that the nuclear fusion within the star simply goes out of control causing the star to explode.

A black hole is one of the last options that a star my take. Not any star can become a black hole. For instance, the possibility of our sun becoming a black hole is highly unlikely, simply because it is too small. If the core of the star is so massive then it is most likely that when the star's gases are almost consumed those gases will collapse inward, forced into the core by the gravitational force laid upon them. The hole is perfectly spherical and has only three attributes: it's mass, it's spin, and it's electric charge. After a black hole is created, the gravitational force continues to pull in space debris and other type of matters to help add to the mass of the core, making the hold stronger and more powerful. Most black holes tend to be in a consistent spinning motion. This motion absorbs various matter and spins it within the ring that is formed around the black hole. This ring is known as the "Event Horizon." This event horizon is the point where the black hole's gravitational pull begins. Once you cross the event horizon, there is no turning back. If an object were to approach the event horizon, time would slow down to the point in which it would take an infinite amount of time to reach the black hole.

Most black holes orbit around stars due to the f
