Black Holes Argumentative Essay

677 Words3 Pages

Black holes are areas in which huge amounts of mass are compressed together, creating a gravitational field so strong that when it crosses the black hole, not even light can escape. They are the final stage for stars 10-15 times as massive as our Sun, because after they explode into a supernova, the gravity causes them to collapse into themselves. They shrink and compress mass until the former star’s volume is at 0. When this happens, they become infinitely dense and the star’s own light becomes trapped inside. The black holes can only pull in objects of similar or lesser mass, since their gravitational pull is only as strong as their mass. Once a passing object (planets, light, etc.) crosses what is called the event horizon, or when there …show more content…

Stephen Hawking’s original theory, relating to quantum effects, stated that they cause black holes to have a temperature, which causes matter inside of black holes to eventually evaporate. However, this goes against Einstein’s general relativity that says that black holes can only grow in mass. The entire concept is based off of black hole radiation, something that creates a paradox against quantum theory. He also showed how, no matter what goes into a black hole, the radiation that comes out is random. This would make it impossible to tell what had gone inside a black hole. All of this came to mean, in his theory, that information could actually be lost inside black holes. Hawking was eventually proven, and publically said, that he was incorrect, but there were still many unsolved mysteries about black holes. A physicist, Juan Maldacena, came up with a mathematical formula that would explain the black hole evaporation. It used the superstring theory involving a 2D universe invisible to those existing in the 3D universe to explain it. This would keep the quantum laws intact for the issue of evaporation. However, it still didn’t explain how information was escaping from the black holes, as the information would remain whole even in the 2D world. Marolf, another person working with such concepts, showed that regardless of string theory, every model of quantum
