Essay about Understanding Black Holes

After a time, the hydrogen runs out almost completely, and it collapses. New reactions begin to take place in the core and these reactions cause the star to expand rapidly. As the stars begin to deplete their new fuel, they switch to others. New elements are formed in the cores of stars but they become too heavy. The star has reached its end growth. When it reaches the end, a tremendous amount of energy is released and it begins to shed its outer layers, the gravity is too weak hold onto them anymore. Once the layers are removed, in the stars place is a fiery core called a planetary nebula. Eventually, the core runs out of fuel and it collapses. This star is now in a very dense state, and is called a white dwarf. Eventually, the white dwarf cools until it no longer shines. This dead star is called a brown dwarf.More massive stars, however, have more violent ways of dying. Some stars turn it into a supergiant. Supergiant stars are extremely bright, and are extremely large. Supergiant stars cores, can collapse violently and suddenly. This collapse causes a tremendous explosion, called a

After the core of a star has depleted all its hydrogen in fusion, it undergoes its final stages of its life, or in other words, its death. The process path of a dying star depends on its mass. Low mass stars, from about 0.4 up to 8 solar masses will evolve from a planetary nebula to a white dwarf. Stars with larger the 8 solar masses will form supernovae, than either a neutron star for intermediate stars (8-25 solar masses) or a black hole for high mass stars (greater than 25 solar masses).

The life cycle of the star is a long process that has taken place for billions of years and will continue to take place long after our star is no longer in existence. In this essay I will be explaining the magnificent process of how a star is first born till the end of its life cycle. First, I will be explaining how the star is first formed in all its beauty big or small. Then, I will be explaining the path of an average star like our own sun will take. After, I will be explaining the journey of a massive star in all its glory till its destructive end. All stars are first formed in clouds of gas called nebulae, turbulence deep within the nebulae causes cores to form as the mass begins to grow the nebulae begins to collapse upon itself due to

Prior to this symposium, physics was not very high on my interest list. However, due to both Dr. Neil Cornish and Dr. Nicholas Yunes, they ignited a strong interest in this field in me. Both professors discussed black holes and experimental tests on certain theories in an extremely enthralling manner. Not only were their presentations interesting, but they succeeded in altering my previous viewpoint on physics. Due to

“Black holes are perhaps the most exotic objects to impinge on the cosmic consciousness. They are formed when matter such as that from a dying massive star collapses in calamitously under its own gravity. forming a region of space in which the gravitational is so strong that it swallows all matter and radiation that come near it.” - Christopher Reynolds (Anderson, 2010).

Type II supernova results from the rapid collapse and explosion of a massive star. For a star to explode as a type II supernova it must be several times more massive than the sun. it is estimated that their mass must be at least 8 times greater than that of the sun, but no more than 40-50 times the suns mass.

During the condensing of the star’s core, the neutrinos are able to escape, but the neutrons are squished together so much that their density is the same of an atomic nucleus’ density. A violent explosion happens during this process and its called a “supernova”. To put this into perspective, imagine taking something the size of our sun, if not bigger, and compacting it into an area the size of a city. This is so dense that just a teaspoon of it would weigh about 1 billion tons! Crazy, right?

Black holes have been theorized since 1916. However, no scientist has ever discovered a black hole in certainty. In theory, A black hole is created when a star of three or more solar masses collapses. “One solar mass is equal to the mass of the sun,” (Mclintock 1). A star collapses when the outward push of the combustion reaction no longer has the required forces compete with the inward pull of gravity. Most astronomers believe that the Milky Way contains millions of theses invisible devils, which are massive stars that have collapsed. In theory, anything could become a black hole if it were simply compressed into its Schwarzschild radius. For instance, Mount Everest has a Schwarzschild radius that is less than a nanometer,

Mysteries of black holes always unknown as in where they come from. “Black holes form when the center of a massive star collapses in on itself.” When this occurs, it causes a supernova. A supernova is a star that increases greatly in brightness because of a catastrophic explosion that ejects most of its mass. The parts left over from the supernova collapse in onto itself forming a black hole. This well-known black hole is called a stellar mass black hole. “Scientists believe supermassive black holes have formed at

As more material is pulled into a black hole, it grows bigger and its gravity strengthens (Sipiera 29). Also, a black hole’s gravitational pull is so strong that light can even be pulled into the hole (Jefferis 4). Next, black holes are the last step of the life of a star. Although a black hole’s gravity is strong, only a small part of space will be swallowed. Because black holes are able to pull light into themselves, they cannot be seen. These are a few of the facts that scientists have uncovered.

I walk into the secret annex and all I hear is Mrs.Vaan Daan screaming bloody murder, and into where i hear the shrieks of pure terror and agony. I wounder what is going on? It was so loud i almost forgot that they were trying to hide. I heard the wails of

The gravitational radiation emitted by the Solar System is far too small to measure. However, gravitational radiation has been indirectly observed as an energy loss over time in binary pulsar systems such as PSR B1913+16. When two neutron stars merge or black holes’ form they create detectable amounts of gravitational radiation. Gravitational radiation observatories such as the Laser Interferometer Gravitational Wave Observatory (LIGO) have been created to study the problem. In February 2016, the Advanced LIGO team announced that they had detected gravitational waves from a black hole collision. On September 14, 2015 LIGO registered gravitational waves for the first time, as a result of the collision of two black holes 1.3 billion light-years from Earth. This observation confirms the theoretical predictions of Einstein and others that such waves exist. The event confirms that binary black holes exist. It also opens the way for practical observation and understanding of the nature of gravity and events in the Universe including the Big Bang and what happened after

When many people think of black holes they think of a giant portal in space eating galaxies and moving on to the next as most commonly seen in pop culture shows such as Star Trek. The reality is however that while we spend a lot of time studying them we know very little about Black holes. What we do know is that there are two types of black holes based on their relative size, there are Stellar black holes and Supermassive black holes. Stellar black holes are only a few times larger than our sun while Supermassive black holes are about a billion times larger than our sun. Both types of black hole are formed when a star implodes and there is nothing left to burn. This can be seen by observing how light and matter cooperate with the event horizon, a second way to detect black holes is through X-Rays by noticing when stars rotate around a gap in space. By studying the speed of stars orbiting, and calculating their paths it is possible to determine the mass and size of a black hole. Using these pieces of evidence we can determine that stellar black holes do exist and
