There are so many black holes in the universe that they are impossible to number. Although the expansive number, the closest black hole to earth is “1,600 lightyears away” (Marel). But what exactly is a black hole? A black hole is a place in space where matter has been compressed into a small space. This amplifies the force of gravity so much so that “even light cannot get out” (Dunbar). Black holes can vary in size, but their size does not determine the amount of mass inside of them. A “stellar” blackhole “can be up to 20 times more than the mass of the sun” , and a “supermassive” black hole can “have masses that are more than 1 million suns together” (Dunbar). Not only are black holes and supermassive black holes different in size but also …show more content…
Einstein saw gravity as a manipulation of space and time, and objects can distort the fabric of space-time the more massive they are. Jay GaBany describes this phenomenon like how a “bowling ball placed on a trampoline stretches the fabric and causes it to dimple or sag, so planets and stars warp space-time,” (GaBany). Each object that creates a “dent” in space-time has an escape velocity, the speed it takes to get out of the gravitational pull of that object. Some object’s “massiveness” (their mass related to their size) can cause their escape velocity to reach the speed of light, at which point “neither matter nor radiation can escape from the object's surface. Additionally, atomic or subatomic forces become incapable of holding the object up against its own weight.” (GaBany). The object then collapses into “an infinitesimal point” and creates a bottomless pit in the fabric of space time, or a black hole. (GaBany). While Einstein performed much of this research, the first to give the black hole its iconic name was astrophysicist, John Archibald …show more content…
However, stellar-mass black holes form when a star can no longer produce energy at its core. The radiation from inside the star maintains the outer layers until gravity forces it to collapse, then the outer layers may fall into the black hole or blast into space. At the center of every black hole, there is a singularity, a point where immense amounts of matter are compressed into a miniscule amount of space, so small that according to equations, has no dimensions. As a person approaches a black hole, if the event horizon- “the point at which the gravitational force precisely counteracts the light's efforts to escape it,”- is crossed, there is no escaping the black hole (McIrvin). If a person were to enter a black hole, they would be in free-fall until they got close enough to the singularity, in which forces due to the curvature of space-time will push and pull them in different directions until they “look like a piece of spaghetti”. (McIrvin). Then, at the singularity, all laws of physics cease to
