# Can the Universe be spatially closed and expand forever?

In the lambda-CDM model, the Universe is spatially flat, and will expand forever. Is possible that a spatially closed Universe expands forever?

$\Lambda > \frac{4\pi G \rho}{c^2}$
Where $\rho$ is the critical energy density (of matter) of the Universe, will cause it to expand forever.
NB Where $\Lambda$ is equal to this value you get the (unstable) Einstein static Universe.
