Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Many laws take mathematical forms, and thus can be stated as an equation; for example, the law of conservation of energy can be written as =, where is the total amount of energy in the universe. Similarly, the first law of thermodynamics can be written as d U = δ Q − δ W {\displaystyle \mathrm {d} U=\delta Q-\delta W\,} , and Newton's ...
Newton's law of universal gravitation, which describes classical gravity, can be seen as a prediction of general relativity for the almost flat spacetime geometry around stationary mass distributions. Some predictions of general relativity, however, are beyond Newton's law of universal gravitation in classical physics.
The fine-tuned universe hypothesis is the proposition that the conditions that allow the existence of observable life in the universe can only occur when certain universal fundamental physical constants lie within a very narrow range of values.
His law of universal gravitation implied there to be instant interaction among all objects. [3] [4] As conventionally interpreted, Newton's theory of motion modelled a central force without a communicating medium. [5] [6] Thus Newton's theory violated the tradition, going back to Descartes, that there should be no action at a distance. [7]
There is a philosophical debate within the physics community as to whether a theory of everything deserves to be called the fundamental law of the universe. [57] One view is the hard reductionist position that the theory of everything is the fundamental law and that all other theories that apply within the universe are a consequence of the ...

The laws of physics transform from one inertial frame to another according to Galilean relativity, leading to the following objections to absolute space, as outlined by Milutin Blagojević: [10] The existence of absolute space contradicts the internal logic of classical mechanics since, according to Galilean principle of relativity, none of the ...
