relativité générale

General relativity, formulated by Albert Einstein, describes gravity not as a force but as the curvature of spacetime caused by mass and energy. Imagine spacetime as a flexible fabric; heavy objects like stars and planets create dents or curves in it. These curves influence the motion of other objects, making them follow curved paths—what we perceive as gravity. This theory explains phenomena like black holes, gravitational waves, and how light bends around massive objects, providing a more comprehensive understanding of the universe’s structure and behavior compared to earlier Newtonian views.
