Gravitaatioilmiö

Gravitaatioilmiö, commonly known as gravity, is a fundamental force of nature that attracts any two objects with mass. This attraction is what keeps planets in orbit around stars, holds galaxies together, and causes objects to fall to the ground when dropped.

The strength of the gravitational force between two objects depends on their masses and the distance between them. More massive objects exert a stronger gravitational pull. Conversely, the force weakens significantly as the distance between the objects increases. This relationship is described by Newton's Law of Universal Gravitation.

Albert Einstein's theory of general relativity provides a more comprehensive understanding of gravity. It posits that gravity is not a force in the traditional sense, but rather a curvature of spacetime caused by the presence of mass and energy. Massive objects warp the fabric of spacetime around them, and other objects moving through this warped region follow curved paths, which we perceive as gravitational attraction.

While we experience gravity daily as a downward pull, its effects are far-reaching, shaping the structure and evolution of the universe on the grandest scales. The study of gravitaatioilmiö continues to be a cornerstone of physics, with ongoing research exploring its role in phenomena like black holes and gravitational waves.
