In modern day physics, Black Holes have dominated the spotlight for quite some time. While the concept has answered many questions, it has also introduced hundreds more. There is believed to be a black hole at the center of our galaxy, the Milky Way galaxy. Black holes were first proven to exist in the 1970’s when a few scientists identified a black hole called Cygnus X-1. Since then, an intense amount of study has been dedicated to discovering the various properties of black holes.
Merriam Webster defines a black hole as: a celestial object that has a gravitational field so strong that light cannot escape it and that is believed to be created especially in the collapse of a very massive star. The idea of a black hole was first proposed by a one John Michell in the 1700’s. The idea itself was not actively pursued until after Einstein’s theories of general relativity were accepted. Scientist pre-Einstein could not comprehend how a wave such as light could hypothetically be influenced by a force such as gravity. However, when Einstein opened the door, black holes suddenly became a possibility, and it took a better half of a century before their existence could be proven, let alone monitored. Now, we have a better understanding of what black holes are, and how they come to be.
Black holes are believed to be the result of the explosion of a very large star, at least 25 times larger than our own. When the star explodes, much of its matter is blown out into space, resulting in a supernova. However, some of it condenses into a black hole. The approximate mass of the resulting black hole is probably slightly larger than the mass of our sun. There are black holes of much larger sizes, however, and they are generally found at the center of galaxies. One such “supermassive” black hole resides at the center of our own galaxy. The origins of these are more or less left to conjecture, however scientists have some strong ideas. One such is that they have simply grown exponentially by sucking in gasses and stars that are in large supply at the center of a galaxy.
Black holes have strange properties that can be difficult to explain. A black hole is particularly...
