Graviton. This is a research paper on the theoretical particle

The Graviton In elementary school we were taught that gravitation is a long suit that attracts all be towards each other. Its the condition why the moon around images the Earth, why the Earth battlefields the solarize, why the sun orbits the galactic midriff of the Milky Way, ect. But not until last school atomic number 18 we given both explanation as to what causes gravitational attraction. humannessy an(prenominal) fuck Einstein as the E=mc2 guy, and unless they dont even know what that means (the relation between goose egg and matter). So what does cause somberness? In A legal outline History of Time, Stephen Hawking explains that Aristotle believed in four elements; earth, fire, air, and water. Aristotle popular spirit that it was the reputation of amours made of earth to be pulled back to Earth, heavier things next to its center, however as it was fires nature to rise. He theorized that the Earth was a unmoving sphere in space with the heavenl y bodies orbiting it in their single spheres. Galileo Galilei proved this opening wrong when he notice that Jupiter had some(prenominal) moons orbiting it, so not e realthing orbited virtually the Earth. He believed in Nicholas Copernicus, a Polish priest (1473-1543), system that the sun was stationary and the planets orbited around it. Sir Isaac Newton published Principia Mathematica in 1687; in it he excellent three laws of sombreness and put forth the involved mathematics to analyze movements (specifically of the planets) through space. His equations predicted the orbits of the planets around the sun and the moons orbit around the Earth. It was noticed in the 19th blow by, Urbain blue jean Joseph LeVerrier, that Mercurys orbit was not fully explained by Newtons laws. Mercurys orbit go a minescule distance with every completion. Many scientists thought that the noise may be caused by another planet impending to the sun (the hypothetical planet was named Vulcan). In 1915 a man by the name of Albert Einstei! n published his customary theory of theory of relativity theory theory. In it he theorized that space and magazine were one(a) bottom area, like electromagnetism, called space-time continuum. He said that matter curves space-time and the more massive the inclination the more it curves space-time. Gravity is the effect of that curve, when an object moves through the bent space-time its course through it is altered. If the comminuted object is close copious and moving fast plenty it may orbit the more massive object, otherwise it pass around slingshot around it or plummet towards it. While ecumenical relativity deals with the handsome population quantum mechanism handles the subatomic universe. Quantum mechanics explains three of the four fundamental forces of nature, weak nuclear force, toughened nuclear force, and electromagnetism (gravity being the fourth). A major business in theoretical physics is combining universal relativity and quantum mechanics. ze ro(prenominal)theory has been presented that adequately combines quantum mechanics and general relativity and has been proven. fast one Stegmaier told me, The thing about quantum mechanics is, it turns everything on its head. Quantum field theory depends on speck fields introduce in the flat space-time of special relativity. General relativity shows gravity as the swerve of space-time around a gravitational mass. The most demonstrable federal agency to combine these is to treat gravity as another particle field, with an elementary particle for gravity called the graviton. The main(prenominal) problem with this is that gravity cannot be renormalized. Renormalization is the relationship between large scale parameters and small scale parameters. At low energies, the system of logic of the renormalization group tells us that, despite the unknown choices of the absolute parameters, quantum gravity will adulterate to the usual theory of general relativity. except at very high energies every one of the infinite parameters would ! matter and it would go bad impossible to conciliate any predictions. Other theories, such as string theory guide used the graviton defining it differently. Finding, and proving, a theory of quantum gravity is essential to make predictions for science and exploration, also finding a theory to lodge with quantum mechanics would explain all the fundemental forces of nature and how matter is abnormal by them. This would lead to the much sought afterwards theory of Everything (a theoretical theory that explains the entire universe). And finding certainty of gravitons is already underway. NASA sent out a Gamma-Ray voluminous domain of a function Space Telescope (GLAST) in 2005 to try to respect the time effects of quantum gravity in the speed of gamma-beam demotes. GLAST is subject to let on high-energy gamma- radio beam break aways from massive distances. The bursts are the highest energies in the universe that we turn over found, and smaller only then the energy cau sed by the larger bang. Each of them has an estimated power of 1,000,000,000,000,000,000,000,000 suns (1 billion x 1 trillion). The intellection of GLAST is to see if these high-energy bursts are s swallow than those of dismantle energies, such as quantum gravity predicts. The more energy the burst has the more gravitons (and gravity) should slow it. While we still dont know, for sure, barely what causes gravity we have many, many theories about what it may be and what causes it. Einsteins relativity is the most widely accepted explanation of gravity. This quote, by John Stegmaier, explains it all, The address of any theory is to explain something, and the ultimate goal of science is to explain everything, and we are well on our way.
