In accordance with Friedmann-Lemaitre-Equation there are three different possibilities of space curvature which can be described mathematically and imparted graphically or analogously (Closed, Openend or Flat Universe). In the poster attached a fourth (only) graphical based possibility is plotted. Is this sketch even describable within Friedmann-Lemaitre-Equations? How can we interpret this sketch? A Universe that is truly infinite, although it has a defined start and a defined end point? Does it suggest a universe which goes back in time when asymptotical limit of Expansion is exceeded? And a collapse when asymptocial limit is exceeded again, but backwards? What would be a 3-Dimensional mathematical object to describe the plot (closed hypertorus, while closed means without a connection in the center?)? Is it even describable mathematically without Paradoxons, or is it an example of a plot that can be plotted abstractly but not defined abstractly in accordance with logic equations? What numbers for curvature parameter k and density Parameter Ω make sense for this sketch?
Thankful for every form of discussion!
