Gravity and Its Theory - 2158 Words

Gravity and its theory, is relatively new. Scientists still discover new correlations that they attribute to Gravity. Greek philosophers attributed the â€Å"natural motion† of the planets and stars as a part of the gods’ realm. They did not realize that gravity was involved until astronomers like Galileo and Brahe in the 1500s, discovered that the Earth and other planets revolved around the sun. Kepler later showed that they moved in an elliptical orbit, not in a circular pattern, which brought speculation as to why it occurred that way. Gravity is a force of attraction that exists between any two objects such as the force between the Earth and the sun and between us and the Earth. It is the weakest of the forces of nature but also the most dominant force. The law of universal gravitation states that every object attracts every other object with a force that, for any two objects, is proportional to the mass of each object and inversely proportional to the distance between the objects squared. Gravity can be described by the formula: The latter which exemplifies the â€Å"inverse-square law†, which states that gravitational force varies as the inverse square of the distance between the two objects. As a result, the effect of Gravity falls rapidly as the distance increases between two objects. Weight is determined by gravity as it is the force of attraction between the Earth and you. Gravity also determines the â€Å"escape speed† for an object such as a rocket or space shuttle.

String theory is a theory that states that the universe is made up of vibrating strings. It is the best candidate for a quantum theory of gravity. String theory attempts to be a theory of everything. there are two types of string theories. the first time has strings that are in loops that can break into open strings and the other has loops that cannot break into open strings. the elementary strings have a number of excitation modes - that are the elementary particles observedRead MoreEssay about Physics of Black Holes845 Words   |  4 Pagesattempt to shed some light on these mysterious formations, and will inform you the reader of the most popular and widely accepted theories surrounding them. Karl Schwarzschild is credited with being the brilliant astronomer who developed the concept of black holes. In 1916, using Einsteins general theory of relativity, he began to make calculations about the gravity fields of stars. He concluded that if a huge mass, such as a star, were to be concentrated down to the size of an infintessimal pointRead MoreStephen Hawking1703 Words   |  7 Pagesphysics even though he would have preferred math. He moved onto Cambridge University to work on his PhD in cosmology. Hawkings career has focused upon the cosmic entities known as black holes, and has extended to specialized areas such as quantum gravity, particle physics, and supersymmetry. A field of study that Stephen Hawking is known for is cosmology. Cosmology is the metaphysical study of the origin and nature of the universe. A brief synopsis of Hawking indicates that, according to HawkingRead MoreString Theory925 Words   |  4 PagesString theory is defined by Merriam-Webster as, A physical theory in which one-dimensional loops travel through space and also merge and lyse as time elapses. This is in contrast to ordinary quantum field theory, which predicts point particles that emit and absorb each other. String theory is a candidate for a Theory of Everything. String theory would solve the long fight between Einsteins theory of relativity and Quantum Physics.

Einstein noticed this, and learned that space, gravity, and time work together like a Spiral Wishing Well. He says that space is flat with no matter, but when there is matter, like the earth, the fabric of space warps and curves. One must imagine the hole of the Spiral Wishing Well as the earth and the penny rotating around it is like the moon to see how space warps and how the medium that affects gravity is spaceRead MoreEssay about String Theory926 Words   |  4 Pagesnbsp;nbsp;nbsp;nbsp;nbsp;String theory is defi ned by Merriam-Webster as, â€Å"A physical theory in which one-dimensional loops travel through space and also merge and lyse as time elapses.

Regarding the laws of physics, relative gravity should be able to explain how the galaxies are moving. Relative gravity involves the force of gravitational energy as a universal law. As Alok Jha states, It encapsulates the idea that all the particles of matter in the universe attract each other through the force of gravity (Jha, 2013). In other words, gravitational attraction extends to planets attracting each other, not having
