gravitaatiovuorovaikutus
Gravitaatiovuorovaikutus, often referred to as gravity, is one of the four fundamental forces of nature. It is the force of attraction between any two objects that have mass. The more massive an object, the stronger its gravitational pull. Similarly, the closer two objects are, the stronger the gravitational force between them. This force is responsible for keeping planets in orbit around stars, stars within galaxies, and galaxies within clusters.
The modern understanding of gravity is described by Albert Einstein's theory of general relativity. This theory
Newton's law of universal gravitation, developed centuries earlier, provides a very accurate approximation of gravity's effects
While gravity is the weakest of the four fundamental forces at the microscopic level, it is dominant
