I did some investigations and my conclusion is that it is a virtual volume. But volume is an extensive variable. The trick is then to make it intensive. I dont know how to do that.
You are not alone there,neither do I!

OK that went over my head. I thought I heard or read that Euclidian geometry was being used for our universe though, or is that wrong also?
Best,

It depends what you mean here. If you're talking about the everyday person, calculating everyday things on the surface of the earth then yes, they would use Euclidean geometry. However, cosmologists or more specifically astrophysicists do not. This is due to Einstein's theory of relativity which says that space(time) is curved by objects sitting in the space-time. Thus, if one wants to study the universe, then one will need to use Non-Euclidean geometry. More specifically, such people would use Riemannian geometry which is basically a version of non-Euclidean geometry in which the curvature of the space-time varies from point to point.
I hope this helps, and wasn't unnecessarily complicated!
