Informative Essay: The Physics Of Black Holes

Term paper outline-Death of stars http://www.space.com/6638-supernova.html http://en.wikipedia.org/wiki/Stellar_evolution Abstract (summar of paper) When observing a star, the lager it is the shorter its life is going to be. The smaller it is the longer the life. Shorter life is not saying much though, as the most massive stars live for billions of years. When a

Black holes are formed by an interesting phenomenon. When stars collapse on themselves, they create what we know as black holes. This collapse can cause a giant supernova, which can blast a part of the star into space. This largest black holes astronomers believe, were created when the “Big Bang” happened. This means black holes grow over time.

Black holes - the strange scientific phenomenon that has astounded physicists and astronomers alike for decades. Popular subjects in science fiction novels, black holes are one of the greatest enigmas of the scientific world. Even today, the concept of a super-dense ball of matter that not even light can escape from is somewhat farfetched, and many scientists disagree with each other about nearly every aspect of a black hole. This project will attempt to shed some light on these mysterious formations, and will inform you the reader of the most popular and widely accepted theories surrounding them.

They are scattered throughout the galaxies. A stellar black hole is the product of the death of a giant star such as a pulsar or a neutron star. Black holes in general are very rare because most stars are not massive enough to create them. When a star stops producing fusion energy, the equilibrium of the star no longer exists. Without the star producing any fuel, there is no pressure created that can hold the star in place. The pressure that a star creates is used to prevent the gravity from crushing the core. Now that there is no pressure pushing outward, the gravity becomes so violent that it crushes matter to the point that it is completely destroyed. At this point, black holes are born. Black holes are created in rare occasions. During the death of most stars, they slowly dim out or explode into trillions of microscopic particles. For example, the sun, which is a red dwarf, will slowly die out. Eta Carinae on the other hand, located 8,000 light years away from Earth, is likely to explode within the next several hundred thousand

Common types of black holes are produced by certain dying stars. A star with a mass greater than 20 times the mass of our sun can produce a black hole at the end of its life. Black holes are usually only created by the death of a very massive star. When a very massive star dies, it explodes into a supernova. The outer parts of the star are launched violently into space while the core completely collapses under its own weight. If the core remaining after the giant explosion from the supernova is very massive, there

​Black holes are associated with the destruction or dying of relatively large stars. Black holes do not happen every time such stars are collapsed. The collapsing of stars mostly result in

The SVU crew decides to throw a little get together at a local bar. You were relatively new to everyone, becoming another hired junior detective for Lieutenant Benson, who tells you to call her Liv on your off hours.

 1 H o w are Blackholes formed? A blackhole occurs when a giant or supergiant start dies. But before the star dies their is a fusion reaction going on constantly throughout its life time. This fusion reaction can be di erent from star to star ff depending on its age. For a young star the reaction is a proton to proton fusion, a middle aged star can have a carbon reaction and a much older star, which is collapsing on itself has a helium fusion reaction. Once a star has finished reacting all of the helium it has the core begins to 'eat' it's self instead of the helium. This makes the core have a stronger and stronger gravitational pull. After the core has 'eaten or suck up everything into its fusion reaction it collapses due to so much compressed mass in a small space which forms a giant explosion creating a supernova which then turns into a singularity. Thus

Black holes are a staple in the study of our unknown universe. The current understanding of general relativity allows something like a black hole to exist due to the strange properties surrounding them, as well as the effects on their surroundings. Black holes are defined by Chaisson's Astronomy as "a region of space where the pull of gravity is so great that nothing, not even light can escape" (Chaisson, 2013). This definition is very broad, simply stating the effects of what we call a black hole. Indeed, there is a lot of thoughtful assuming done when discussing this phenomena, however, what if everything we thought we knew about black holes was wrong and black holes didn't actually exists. That is exactly what a small group of scientists and astronomers think is the case.

When a giant star collapses upon itself it creates a supernova. After a supernova occurs, a neutron star appears. It is very small, but extremely dense. It is unknown what type of matter it is made of.

The formation of supermassive black holes has been questioned in physics since the day of their discovery. Just how is something so large and powerful formed? Are they a danger to us? What lies beyond the event horizon? These are all questions that have been asked and not yet answered

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

A black hole is remnant of a former star which has gone past its lifetime. They are one of the/if not the most mysterious phenomena that has ever existed in the universe. Black Holes are formed when massive stars, about 20 times the mass of our sun run out of fuel

If theories of their existence are true, black holes are the most powerful force in the known physical universe. Many people are familiar with the term black hole, but few people actually know anything about them. A black hole forms as a result of a massive star running out of fuel to burn (Chaisson, 193).
