A black hole is a term that many people have heard in various fields of physics. However, few people are aware of the real meaning of the black hole. The problem with the black hole was surrounded by several issues, including what it really has when and how black holes are formed, possibly the researchers viewed a black hole and the “horizon of events” against a black hole. These questions arose because of these issues, including the arguments of scientists who advocate the sight and existence of a black hole
The black hole refers to the theoretical body, which is predictive of the relativity of the prophecy. Gravity activity results in a star with a significant mass swaying. All or most of the mass of the star is subsequently compressed into a small area. According to scientists, the collapse is followed by an infinite collapse of space. The screen-frequency is an obstacle to all, including light, from the horizon of events. This is also called boardder (Frolov, 1998)
People were always arguing about the attack and the existence of black holes, because no one had ever seen them directly. They are available only if their effects are predicted according to their observations. However, there are alternative theories. Some known theories include “Magnetic Eternally Collaping Objects” (MECO). This theory is trying to imagine scientific observations
Most alternative theories, however, will take away the existence of the space-time singularity found in the center of the black hole. However, the argument of most scientists favours an explanation of the black hole, indicating that this is a viable explanation that tries to determine what is going on (Hoft, 1985)
The problem with the black holes is not something new. The debate that can be traced to 18 years
John Michell has written an article in 1784 to predict an object whose radius is 500 times greater than the radius of the sun, even though their density is the same, but the sun can achieve the speed of escape that can be equal to the speed of light. According to Meade, the entity can become invisible. However, not so many people were interested in such a theory at the time. In the end, this theory was forgotten at time 20
The concept of black holes became known after Albert Einstein’s general theory of relativity was published in 1916. Karl Schwartzchild, the physicist didn’ t waste any time before coming to the solution of Einstein’s equation for the spherical mass. This is commonly referred to as Schwartzchild metrics. The results of this decision were unprecedented. The nature of the term used for the expression of radius was ultimately disoriented. For some radius the denominator must be zero. This factor makes mathematical calculations impossible or extremely difficult. Nevertheless, the approach aimed at highlighting the concept of the black hole
Over time, many people support the black hole theory. The deduces of Subrahmanyan Chandrashi, a prominent physicist, were that the stars with a solar mass of 1.44 and above should be charred in the general theory of relativity. In another physicist, called Arthur Eddington, there were some properties that could prevent the collapse. In personal ways, there was evidence that both physicists were right
The development of the theory also influenced Robert Oppenheimer’s physicist. In 1939 Robert predicted a massive star with the possibility of collapsing and creating a unique “frozen star” not only in the projection of mathematics, but also naturally. His prediction is that this collapse can slow down the process leading to freezing at a point in time when it crosses the Schwartztchild ®
radius.According to physics, the light that may emerge from this star will take a red shift in R
In 1967, nearly half a century after the discovery of Schwartchild Radius, Stephen Hawking and Roger Penrose showed that general relativity had caused black holes. Their work had further shown that the collapse had not been prevented in any way. This is an enhanced search function in Pulsary, which allowed John Wheeler to use the word of a black hole during a lecture that was in late 1967. The discovery of Hawking radiation was included in subsequent studies that confirm the ability of black holes to radiate radiation
Another issue is the speculations of the black hole. Theorists and researchers who want to challenge the concept are related to this speculation. An agreement that almost universally exists in today’s world. It’s an agreement on the existence of black holes. Nevertheless, it was always impossible for scientists to agree on the very nature of black holes
There are several unanswered questions about the nature of black holes. According to some staff, the material lost in black holes may appear again elsewhere in the universe. They claim that it’s like a wormhole case. In addition, significant changes have been made in the concept of black holes. Hawking-radiation is one of the most noticeable events by Stephen Hawking, the British physicist in 1974
Hawking radiation means a theoretical projection that focuses on the thermal properties of the black hole concept. Black holes are considered to be very powerful gravitational fields that allow them to draw matter and energy. Jacob Beckenstein tried to explain the theory even more, suggested that entropy of black holes must be clearly defined. This led to thermodynamic development for a black hole that includes energy emissions. In the end, Hawking’s radiation was developed, and it remains influential in the study of black holes (Hoft, 1985)
