Because of this curvature, the paths that objects in [[inertia\|inertial motion]] follow can "deviate" or change direction over time. This deviation appears to us as an acceleration towards massive objects, which Newton characterized as being gravity. In general relativity however, this acceleration or [[freefall\|free fall]] is actually inertial motion. So objects in a gravitational field appear to fall at the same rate due to their being in inertial motion while the observer is the one being accelerated. (This identification of free fall and inertia is known as the [[Equivalence principle]].)

			The [[Einstein field equation]]s <!-- in units for which G=c=1 -->can be written briefly in [[abstract index notation]] as rank 2 symmetric tensors:

			:<math> G_{ab} = 8 \pi T_{ab} \ </math>

			where <math>G_{ab}</math> is the [[Einstein tensor\|curvature of spacetime]] and <math>T_{ab}</math> is the [[stress-energy tensor\|stress-energy]] within it. Many [[exact solutions of Einstein's field equations\|exact solutions of the Einstein field equations]] are known. The solutions to the field equations are [[metric tensor (general relativity)\|metrics of spacetime]]. These metrics describe the structure of spacetime given the stress-energy and coordinate mapping used to obtain that solution.
