    Space: the final frontierAstronomy is a word derived from Greek; it comes from the fusion of two words, the first being “star” and the second “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 a very broad subject, there are of course 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 main theme of all these works is space, in particular 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 point of view) 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, luminosity and a myriad 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 several 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 moving in space has kinetic energy (http://m.teachastronomy.com/astropedia/article/Potential-and-Kinetic-Energy). Kinetic energy is all around us, for example if you are driving down the street and pass two cars of the same make and model, the car going faster will have more kinetic energy than the car going furthest. more slowly. Kinetic energy is visible everywhere in the middle of the paper......depending on their mass and size. They are listed as supermassive, stellar and miniature. Supermassive stars – the type of star located at the center of a galaxy – are the largest black holes among these. Astronomers believe that supermassive black holes develop 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 remnants of large stars, as explained previously. This is 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 expanded rapidly. Some parts may have grown faster than others, creating a miniature black hole..
