Space: the final frontierAstronomy is a word derived from Greek; comes from the fusion of two words, the first is "star" and the second is "law". As the name suggests, astronomy is the study of the stars, as well as countless other aspects of space and the universe in general. Being such a broad topic, there are obviously many different branches of astronomy. These include general astrophysics, theoretical astrophysics, astrobiology, physical cosmology, galactic astronomy… you get the idea. (wiki) There are many. But the general theme of all is space, especially the physics of space. And wherever there is physics, there is mathematics. Like mathematics, astronomy incorporates a healthy (or not so healthy, depending on your perspective) use of symbols. These symbols are often Greek letters, as in many other forms of equations. These symbols are commonly used in formulas. There is practically an astrological formula for everything; formulas to calculate brightness, distance, brightness and a host of others. (http://www.uncg.edu/cla/courses/shelmerd/grkalpha.gif) The formula in fig. 1 is used to calculate the kinetic energy (the energy an object has due to its motion) of an object. This formula is applicable in many ways. For example, it can be modified to find the energy of incredibly small units, such as molecules and atoms. This modified formula can be seen in fig. 2. Every object that moves in space has kinetic energy (http://m.teachastronomy.com/astropedia/article/Potential-and-Kinetic-Energy). Kinetic energy is everywhere around us, for example if you are driving down the street and you come across two cars of the same make and model, the car going faster will have more kinetic energy than the slower one. Kinetic energy is seen in the... center of the paper... based on their mass and size. They are listed as Supermassive, Stellar, and Miniature. The largest black holes are supermassive, which is the type of star found at the center of a galaxy. Astronomers believe that supermassive black holes grow when an object passes the event horizon (an imaginary sphere around the black hole where the escape velocity is greater than the speed of light). Stellar black holes are the remnants of large stars, as explained above. These are the most commonly formed type of black hole. Finally, there are miniature black holes, like the one mentioned in the Oreo analogy. A possible origin of these miniatures would be at the dawn of our universe, during the Big Bang. The matter would have been compressed into a single point and then rapidly expanded. Some parts may have expanded more rapidly than others, thus creating a miniature black hole.
