The critical density determines the Universe evolution along time. So, by measuring this density, we could know about the finite or infinite age of the Universe.(adsbygoogle = window.adsbygoogle || []).push({});

But we don't know from General Relativity if our Universe isspatiallyfinite or infinite.

As far as I know, such question could be only answered from Topology.

If so, are there enough observational evidences to sustain any topology?

What would be the observational keys to elucidate this topology?
