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.

As you get closer to the center, or what scientists call the "singularity", the theory of spaghetti effect comes into play. That is, the gravitational pull of the center of the black hole is greater at your feet than your head, thus pulling stronger at your feet and stretching you out to a point of infinite thinness. If you were to reach the singularity you would be in a place where time does not exist and all of Einstein's laws will fail. The core compacts into a mathematical point with virtually zero volume, where it is said to have infinite density. For instance, if the Earth were to be squeezed into a black hole, it would end up as the size of a marble. There are many effects that a person would feel as they entered a black hole. As they fell into the black hole, they would instantly be stretched out because the difference between the gravitational pull on his head and feet would be so powerful (the spaghetti effect). If they could look back as they fell, the entire history of the universe would flash before their eyes (but once inside they are unable to communicate with anyone outside the event horizon). And as they neared the singularity, they would feel themselves being torn apart atom by atom. Another example of what would happen around a black hole is that if you and your friend were outside the black hole for a while, then you went back to join your friend, you would find that the friend has aged more than you had during your separation.

Most black holes orbit around stars due to the fact that they once were a star, and this may cause some pro
