Gravity is what gives you weight. Of the universe’s fundamental forces, only one dominates every moment of our conscious experience gravity. Gravitation is what holds our world together. However, gravitation is not the same in every place of Earth.
Gravitation is one of the four fundamental forces in the universe, alongside electromagnetism and the strong and weak nuclear forces Despite being all-pervasive and important for keeping our feet from flying off the Earth, gravitation remains, in large part, a puzzle to scientists. Infamous 1687 treatise “Philosophiae Naturalis Principia Mathematica,” Newton described what is now called his law of universal gravitation.
F = Gm1m2/r2
Where F is the force, m1 and m2 are the masses of two objects and r is the distance between them G the gravitational constant, is a fundamental constant whose value has to be discovered through experiment. A perpetual force of mystery Gravity perplexes scientists in other ways, too.
Cosmically, gravity is just as consequential. From collapsing hydrogen clouds into stars to gluing galaxies together, gravitation represents one of just a few players that determine the broad strokes of the universe’s evolution.
Gravity and Relativity
Then Einstein gave updated theory which is famous as theory of relativity. I have already written a article on Gravity and Relativity.
