How Did Isaac Newton Contribute To The Discovery Of Gravitational Waves

1. Identification: In the 17th century, various fields of science began to advance. Isaac Newton combined the ideas of earlier scientists, and developed the concept of gravity.

In 1916 Einstein proposed his new General Theory of Relativity that built upon Newton's Universal Theory of Gravitation which showed "that gravity is responsible for the motions of both planets and falling objects near the Earth" (Fix, p 86). Einstein' theory "describes gravity as a curvature in four-dimensional spacetime" (Singh, p. 502). The original intent of the theory was to explain the inaccuracies of Mercury's orbit when using Newton's law and the Sun's bending of light.

First, Sir Isaac Newton discovered gravity after observing an apple fall to the ground. However, one of his most notable contributions is not the discovery of gravity but his discovery that gravitation is universal. The force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers.

Before Newton talked about gravitation the main knowledge of scientists was a elementary knowledge of optics, mechanics and astronomy.Copernicus Kepler and Galileo provided the background knowledge of the stars and planets, but Newton used their data to discover the whole gravitational system.10Newton reasoned that the planets and all other physical objects in the universe moved through mutual attraction of gravity.Newton said that every other object in the universe affected every other object through gravity.This explained why the planets move in an orderly fashion. Newton found that “the force of gravity towards the whole planet did arise from and was compounded of the forces of gravity towards all it’s parts, and towards every one part was in the inverse proportion of the squares of the distances from this part.”Newton proves all of this mathematically. This was known to be the single most important contribution to physics that ever has been made.11

Have you ever heard the legend about Newton and how he discovered gravity? Legend has it young Newton was sitting under an apple tree and all of a sudden he gets hit on the head apple. This legend is supposedly the real reason how the laws of gravity were created but it’s not all true. The real story which was told by Isaac himself is, he was barely looking out the window when he happened to see the fruit drop. Even then, some Newton scholars think the story involving the apples was made up.

Gravity is known all around the world.All things are controlled by it.It keeps all things down.How much do you really know about the force and the founder though?Sir Isaac Newton was born on January 4,1643.Newton discovered the light spectrum and gravity.He published his discovery of gravity in his book in 1687.

Galileo also did experiments on gravity. Galileo demonstrated the laws of gravity “by dropping bodies of different weights from the top of the famous Leaning Tower, that the speed of fall of a heavy object is not proportional to its weight, as Aristotle had claimed”(“Galileo”). Galileo proved that Aristotle’s theory about gravity was incorrect and that no matter what size or weight all objects fall at the same velocity(Drake 22). He also helped improve the telescope. His improvements to the telescope allowed him to view not just stars but also Jupiter's moons, spots on the sun, and the uneven rough surface of our moon in 1608.

Sir Isaac Newton Rough Draft Sir Isaac Newton was the person who discovered gravity and the person that made the laws of motion. The laws of motion are very important because it helps us understand how gravity and movement work. Gravity is a major thing in our solar system. Without gravity the solar system won’t have the shape it is today. Not just in space is gravity important, but in Earth to.

The Scientific Revolution was a period when new scientific ideas where introduced into society. The Scientific Revolution laid down a foundation in which modern science is heavily based on. An influential figure of the Scientific Revolution is Sir Isaac Newton. He made many advancements in the field of science and mathematics, he discovered Gravity, developed the three basic laws of motion, and co-development of Calculus. Isaac Newton did several thing that positively affected the scientific community during the Scientific Revolution and still affect society today, he recognized the three laws of motion, discovered gravity, and co-developed calculus.

Hello! I appreciate the the statement that Isaac Newton was able to prove incomprehensible concepts, at the time [seventeenth century], by solving, proving, and supporting theories through scientific evidence and data. Moreover, he was the first scientist to benighted in England, which publicized even more his profession and level of intelligence in the field of science and mathematics. In addition, I agree that supply-and-demand is an essential principle for an economic prosper in consideration that the higher the price of a good or service, the less people will demand it; therefore, I understand why you are conflicted between choosing the “most influential” person of the seventeenth century.

I joke, of course. Though the apple never hit my head, its perpendicular descent to the ground is what inspired me. Though I technically did not discover gravity itself, I did develop three rules that can be used to observe how gravity works. These rules are not necessarily restricted to use when observing objects falling. They are also useful when studying orbits, friction, collision, and even prove useful when developing new technologies (Gleick 37).

Here the inspiration appeared and led to the fact of gravity that why the apple fell down and did not fall up? Then Newton formulated the law of universal gravitation.

Gravity and its theory, is relatively new. Scientists still discover new correlations that they attribute to Gravity. Greek philosophers attributed the “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.

Isaac Newton was a young, charismatic, and intelligent person when he found the biggest discovery of his life. Something so important that our society would not be as advanced or as prosperous as it is right now. It all began when Newton was sleeping on the stump of an apple tree when suddenly he woke up due to an unknown object falling on his head. When he saw the apple had fallen down by an unknown force, he began to speculate the causes of the fall. After a magnitude of research, he came to the conclusion that force that pulled the apple towards the ground is also the force which keeps us rooted to the ground as well. He coined the force ”Gravity” and began researching many unknown factors about it. With the help of other scientist and researchers, the understanding of gravity grew. We began to realize that gravity has a bigger role than making an apple fall and that its role has helped keep the ocean from being in the sky to keeping the lands from floating. When they began to apply it to space, they realized that earth is round because of gravity and that we actually circle the sun due to its immense gravitational pulls. Gravity is an important aspect of the human life that can be understood by learning its history, understanding the concepts, and realizing the enormous impact it has on life.

Primordial gravitational waves (GWs) are a theoretical stochastic background of gravitational radiation from the early universe which may be detected from their polarising effect on the cosmic microwave background (CMB) or by future generations of interferometers such as eLISA [1]. Able to propagate through the opaque primordial universe, they could allow us to determine the initial state of the universe as well as gaining a valuable insight into physical processes that occurred at this time. There are several theoretical processes in the early universe which could contribute to this background of GWs including cosmic strings, first-order phase transitions and inflation [2][3].
