What is a supernova?
- A supernova is a giant star that has an extremely high pressure core that contains vast amounts of heat. This causes atomic nuclei to get squeezed together and fuse, creating progressively heavier elements. (Hydrogen => Helium => Carbon).
- If the star has about 8x the suns mass, it can create temp in excess of 5x10^8°C causing carbon to fuse.
- Carbon the fuses into Ne, Mg and Na. Once the core heats up to around 1x10^9°C, Ne will fuse creating more Mg and some O. These elements build up and when the core reaches about 1.5x10^9°C, Oxygen fuses, creating Si. The core heats to around 2-3x10^9°C and Si fuses. As well as some other elements, Si fusion creates Fe.
- Because the star was born massive, it spent the time whilst …show more content…
This accelerates the shrinking process, creating an even more tightly compressed core which generates insanely large amounts of heat. On top of this, the Fe nuclei absorb any of the electrons that are roaming free inside the core, removing yet another support that helped the core sustain its self. This causes the Si nuclei to fuse into Fe in a fraction of a second. The massive gravity of the core causes the star to collapse at a significant fraction of the speed of light. The star goes from being a couple of hundred km across, to a few dozen km across in just a few thousandths of a second.
- At this point, one of two things can happen. If the star is less than 20x the mass of the sun, the collapse will stop at around 20 km wide, creating a neutron star. If the star is more than 20x the mass of the sun, then the collapse cannot be stopped and the core collapses all the way down to a point. A point that not even light can escape, creating a black …show more content…
It is impossible for heat to be moved in any other way as there is no air in space for convection or conduction to occur. Radiation is spread through tiny subatomic particles called neutrinos. These particles can travel through any object unhindered, only rarely interacting with matter making them extremely hard to detect. When a supernova collapses, it brings large amounts of matter towards it, and then sends out a shockwave. This sends all of this matter outwards, but more importantly, it sends the heat generated by the star outwards in every

Blace Hole

...BLACK HOLE A black hole is a theoretical region of space in which the gravitational field is so powerful that nothing, not even electromagnetic radiation (e.g. visible light), can escape its pull after having fallen past its event horizon. The term derives from the fact that the absorption of visible light renders the hole's interior invisible, and indistinguishable from the black space around it. . The idea of an object with gravity strong enough to prevent light from escaping was proposed in 1783 by John Michell, an amateur British astronomer. In 1795, Pierre-Simon Laplace, a French physicist independently came to the same conclusion. Black holes, as currently understood, are described by the general theory of relativity. This theory predicts that when a large enough amount of mass is present in a sufficiently small region of space, all paths through space are warped inwards towards the center of the volume, preventing all matter and radiation within it from escaping. While general relativity describes a black hole as a region of empty space with a point-like singularity at the center and an event horizon at the outer edge, the description changes when the effects of quantum mechanics are taken into account. [pic]Name The term black hole to describe this phenomenon dates from the mid-1960s, though its precise origins are unclear. According to Einstein’s general theory of relativity, as mass is added to a degenerate star a sudden collapse will take place and the intense...

Telescopes in Astronomy

...Telescopes in Astronomy Jennifer Boyer SCI/151 June 12, 2015 Robert Austin Telescopes in Astronomy What people currently know about the universe, along with all of its contents, is due in large part to the invention of telescopes. This paper discusses the science of sunlight and stars by explaining how the telescope has changed people’s view of the universe, as well as their place in it. This essay also discusses the major designs of telescopes, provides a list of each design’s strengths and weaknesses, describes the best places to build ground-based telescopes and why astronomers choose those places, and contrasts the strengths and weaknesses between building telescopes on Earth, in orbit, or even on the moon. Additionally, this paper explains how different frequencies of light tell more about the birth, life, and death in the nature and properties of the Sun, stars, and the universe. Lastly, this essay explains how telescopes operate in wavelengths of light that range from radio waves to gamma rays. How Telescopes Changed People’s View The invention of the telescope significantly impacts the way people in the past and present view the Earth, other planets and solar systems, as well as the universe as a whole (Bennett, J., Donahue, M., & Schneider, N., & Voit, M., 2015). Until the invention of Galileo Galilei's (1564-1642) simple telescope, many people thought that the earth was the center of our solar system (Bennett, J., Donahue, M., & Schneider...

...Evolution Through the Solar System Abstract Over the course the class has been about many different things through our solar system, land features, and more. This week we had to put together a paper describing how evolution has taken place through our solar system. The main objectives of the paper are to include the formation of the planets, the motion of the planets, the early revolution. Also, discussed is the scientists who discovered these properties of our solar system. For example Copernicus, Newton, Galileo, and Kepler. These scientists have all created or in some way helped to discover something new about our solar system. Evolution Through the Solar System Though scientists have been studying the solar systems for years. There are still discoveries made each year. Many of the discoveries have been interesting from the formation and motion of the planets, the early revolution of the planets, and the scientists who discovered what we know today. Formation Scientists have been studying the origin of our solar system for hundreds of years. Some findings are well supported while others are not as well received. The best news is we are not done concluding the formation of our solar system just yet. In 2006, the distant ice-covered body known as Pluto was reclassified as a dwarf and changed the model of our solar system from nine planets to eight. Today a planet is defined as, “A full-fledged planet is an object that orbits the sun and is large enough to have...

Old The Universe

...Approximately 14 billion years ago, the universe that stands today was born. There are various explanations for how it was created. Research shows that they are essential scientific questions and it stimulate scientists to debate their research. Many scientists from all over the world and different time periods work to find the reason behind its creation. The different theories on the origin of the universe have a great impact on the way humans view how the universe was created. The most known is the Big Bang theory and smaller theories include the String theory, the Incredible Bulk theory, the Times Arrow theory and the Steady State theory. (Tate) The universe is almost 14 billion years old. There are two common ways scientists use to calculate how old the universe is. The first method involves measuring the speeds and distances of the galaxies. Scientists interpret that the galaxies were closer together before in the past because all of them are slowly moving further from each other every second. Identifying the current speeds and distances of the galaxies, included with the rate at which the universe is accelerating, permits scientists to calculate how long it took...

Solar Tsunami

...“These eruptions occur when immense magnetic structures in the solar atmosphere lose their stability and can no longer be held down by the Sun’s huge gravitational pull. Just like a coiled spring suddenly being released, they erupt into space.” This means we have a very good chance of seeing major and prolonged effects, such as the northern lights at low latitudes.” The solar explosion that causes the tsunami has been observed by many satellites along with the Solar Dynamic Observatory, NASA. The blasts will reach to a maximum level in 2020 it is estimated. Along with this blast there was another blast of cold air circumference of the sun’s northern pole.  A huge cloud has been thrown in to the space with these related developments.

A Defense of Moral Error Theory

...Free from Error Abstract The type of Moral Error theory I shall defend in the following essay is the kind proposed by J. L. Mackie and later by Richard Joyce. Mackie first advances “error theory” by stating that when most people speak of their moral judgements they are implicitly claiming “ to be pointing to something objectively prescriptive,” but “these claims are false” (1977, p.35). In the first section of this essay i shall introduce and clarify the constituent of error theory I aim to defend. In the next section I consider and rebut stephen finlays recent attack on moral error theory. Finlay takes aim at Mackies conceptual claim that many moral judgements entail categorical reasons, but I find his shots misguided. Consequently I shall consider finlays most powerful rejoinders with the view of again refuting them and arriving at the conclusion that Mackies conceptual and ontological claims hold and moral error theory stands. Mackie endorses a second order moral theory regarding the essence of moral valuing and the character of moral values. Mackie believes that many of the moral judgements we make contain a catergorical imperative element and his thesis that “ there are no objective values” (1977, pg 58) is an explicit rebuttal denying that “ any such categorically imperative element is objectively valid” (1977, pg 69).[1] The objective values that Mackie wishes to refute would be action-guiding unconditionally, not contingently upon any particular agents desired...

Human Resource Management

...great advantages in working in a university which has top students is that you can ask them questions you are not quite sure how to answer yourself! The best students gave clear examples of such a link and then got stuck in to the ‘should’ part of the question often noting the critical difference between competitive strategy and business strategy. Some even went further into corporate strategy, the resource based, and knowledge based view as well as ethics, culture and institutional setting. Surprisingly none of them questioned what was meant by a firm’s HR system. I will follow the same line of argument in this paper with thanks to the students, very few of whom have any intention of becoming HR professionals. We start with some of the classics in strategy and HRM, go on to look briefly at some major studies, or the ones that have influenced my thinking. Thereafter the paper notes the problems with the assumed link with competitive strategy as a dominant, or the dominant, force in determining an HR system. Once the focus is widened to cover business strategy two very interesting, and linked, phenomena can be observed. First, what we thought strategy was all about has changed hugely. Second, our definition of what constitutes HRM (or the management of employment relations) has broadened beyond recognition. This is where the definition of...

Dinosaur Extinction

...Dinosaur extinction is still a major mystery of earth history. In this review article, extinctions in the geological record will be briefly mentioned. Many of the imaginative theories for the extinction of the dinosaurs will also be presented. Within the uniformitarian paradigm, the meteorite impact theory, once considered ‘outrageous’, now is the dominant theory. However, the volcanic theory is still believed by a majority of paleontologists. Both theories have their strengths and weaknesses. The unscientific behavior of those involved in the meteorite paradigm change will be briefly explored. Evidence that the dinosaurs died in a cataclysm of global proportions will be presented, such as the huge water-laid dinosaur graveyards found over the earth. Occasional nonspecific bone-beds and the rarity of fossils of very young dinosaurs suggest a catastrophic death and burial. The billions of dinosaur tracks recently discovered provide testimony to unusual, stressful conditions. Nests, eggs, and babies are a challenge to a Flood model, but there are enough unknowns associated with the data that solid conclusions are difficult to draw. The part that impacts and volcanism play in a Flood paradigm will be briefly discussed. The question of whether the K/T boundary and the extinction of the dinosaurs should be considered a synchronous event within the Flood will be considered. Introduction Dinosaurs bring wonder to children and adults alike. That such great beasts once roamed the earth...

I’m sure you have heard that one, anyone who knows about our solar system can thank the three old dogs. Well, they’re not dogs at all, and at their time they weren’t old but in our time their long gone. Of course, I am speaking about Ptolemy, Copernicus, and Kepler. Funny thing is each one of them challenged and changed their predecessor's work, for the better of course, but we will get to that later. We have these three men to thank for a whole lot of new tricks. To name a few would be, our solar system, the way we form our maps, and we can’t forget the numerous mathematical formulas used to make ideas come to life. In this research paper, we will touch base on the lives of three great astronomers and the tricks they have taught us. We will also see how astronomers of today contribute to our everyday lives. Some say that our first astronomer was a great astronomer. Other say, “Ptolemy was the only great astronomer of Roman Alexandria.” (Brown, 2016) It’s all a matter of opinion, but what we cannot deny was Ptolemy was a great astronomer of his time and today. We do not know much about Ptolemy’s personal life. What we do know about him came from his work. He was born around 85ce in Egypt to a Greek family even though he bore a roman name. To say Ptolemy was diverse is an understatement. He was also diverse in his studies being he was a mathematician, geographer...
