For some distorting ideas, how do you think a man is snoring and an apple accidentally falls down to make such a great invention? The result of the process of "wait and see"? Not at all, it only comes with a genius mind that thinks about the laws of physics, namely gravity. Not only in gravity but Newton offers many other ideas ahead of time. In Newton's law of universal gravitation, Newton describes an enormous mountain whose top is in the Earth's atmosphere, on top of which a huge cannon is set that can shoot a bullet in the direction horizontal out of space.
Newton has no intention of creating a super weapon to shoot alien invaders! His gun is an experimental idea that explains how to put an object into a orbit around the Earth. According to Newton's prediction, if too few gunpowder is given, the shrapnel will fall back to Earth. If too much gunpowder is fired, the artillery shells will disappear into space. However, if fired with a sufficient amount of gunpowder, you will provide the artillery shell with enough velocity that it will fall into a curved orbit around the Earth. And then, the artillery shells will move around the Earth in a certain trajectory.
The experiment was presented in the Principia Mathematica in 1687, in which all particles produced an attractive force and were attracted by other objects. This interaction force depends on the weight and distance of the particle or object. This rule governs all phenomena from falling rain to the orbit of planets. This is a well-known work with many important contributions to classical physics and provides a theoretical basis for space travel as well as the development of future missions. Later, Einstein and 16th and 17th century physicists continued to reinforce Newton's theory to give us insights into gravity today.
