üldrelatiivsust

Uldrelatiivsust, also known as general relativity, is a scientific theory that describes gravity not as a force, but as a curvature of spacetime caused by mass and energy. Developed by Albert Einstein and published in 1915, it is a geometric theory of gravitation. This means that massive objects warp the fabric of spacetime around them, and this warping dictates how other objects move. Instead of being pulled by a mysterious force, objects in free fall are actually following the straightest possible paths, called geodesics, through this curved spacetime.

Key predictions of general relativity include the bending of light by gravity, the existence of gravitational waves, and the phenomenon of time dilation in strong gravitational fields. These predictions have been repeatedly confirmed through various experiments and observations, such as the observation of starlight bending around the sun during solar eclipses and the detection of gravitational waves from colliding black holes. General relativity has become a cornerstone of modern physics, explaining phenomena ranging from the orbits of planets to the evolution of the universe. It is an essential tool for understanding cosmology and astrophysics, and it is also crucial for the precise functioning of technologies like the Global Positioning System (GPS).
