Question

Explain Einstein s field equations

Answer 1

The Einstein Field Equations are ten equations, contained in the tensor equation , which describe gravity as a result of spacetime being curved by mass and energy.  is determined byt he curvature of space and time at a particular point in space and time, and is equated with the energy and momentum at that point. The solutions to these equations are the components of the metric tensor , which specifies the spacetime.

where Rμν is the Ricci .Ricci curvature tensor, named after Gregorio Ricci-Curbastro, represents the amount by which the volume of a geodesic ball in a curved Riemannian manifold deviates from that of the standard ball in Euclidean space
