I want to ask General Relativity is a force or Its a theory which explains how to space-time curve and space-time tells how to move
General Relativity is a theory, where mass/energy determines space-time geometry, and space-time geometry determines the paths of free falling objects. In General Relativity gravity can be seen as an inertial force, that appears only in accelerated reference frames. But it is not a direct attractive force interaction, like in Newton's theory of gravity. The difference between Newton and Einstein become clearer when curve-linear coordinates instead of inertial forces are used:Quarlep said:I want to ask General Relativity is a force or Its a theory which explains how to space-time curve and space-time tells how to move
General Relativity is a theory proposed by Albert Einstein in 1915, which explains the force of gravity as a result of the curvature of space and time caused by the presence of mass and energy.
General Relativity proposes that space and time are not separate entities, but rather are interconnected and can be affected by the presence of mass and energy. This concept is known as "spacetime" and has revolutionized our understanding of the universe.
In General Relativity, mass and energy cause a curvature in the fabric of spacetime, much like how a heavy object placed on a trampoline would cause the surface to curve. This curvature is what we experience as the force of gravity.
Newton's theory of gravity described gravity as a force between masses, while General Relativity explains gravity as a result of the curvature of spacetime. Additionally, General Relativity accounts for the effects of acceleration and motion on gravity, while Newton's theory does not.
One of the most famous examples of General Relativity being proven true is the observation of the bending of light by massive objects, such as stars. This phenomenon, known as gravitational lensing, is a result of the curvature of spacetime predicted by General Relativity.
