theory of gravitation

• Conception scientifique, initialement formulée par Isaac Newton puis affinée par Albert Einstein, qui décrit le phénomène naturel par lequel tous les objets possédant une masse ou une énergie s'attirent mutuellement. Elle explique pourquoi les objets tombent sur Terre et régit le mouvement des corps célestes.

A scientific framework, originally formulated by Isaac Newton and later refined by Albert Einstein, that describes the natural phenomenon by which all objects with mass or energy are attracted to one another. It explains why objects fall to the ground and governs the motion of celestial bodies.

1. Newton's Law of Universal GravitationC1formal

   A scientific law stating that every particle of matter in the universe attracts every other particle with a force proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

   • Newton's theory of gravitation explains why an apple falls from a tree.
   • The theory of gravitation is fundamental to understanding planetary motion.
   • Scientists used the theory of gravitation to predict the existence of Neptune.

2. General RelativityC2formal

   Einstein's modern theory of gravitation which describes gravity as a curvature of spacetime caused by mass and energy.

   • Einstein's theory of gravitation replaced Newton's for extreme conditions.
   • The theory of gravitation in general relativity predicts black holes.
   • Gravitational waves are a direct prediction of the theory of gravitation.
