Einstein field equations in empty space, question about non-zero curvature
In four dimensions, however, ... it is therefore possible to satisfy the field equations in empty space with
a non-vanishing curvature tensor."
"... we conclude that it is only in four dimensions or more … Now, if the $\underline{\text{curvature of spacetime}}$ is related to the $\underline{\text{matter and energy density}}$, then how is it possible that in 4+ dimensions there can be a non-zero curvature …
