                         classical cosmological singularity. It is based on a generalized 
                         function f(x,y) = x 2 + y 2 = (1 \− z)z n which consists of 
                         a cusped coupled isosurface. Such a geometry is computed and 
                         discussed into the context of Friedmann singularity-free cosmology 
                         where a pre-big bang scenario is considered. Assuming that the 
                         mechanism of cusp formation is described by non-linear 
                         oscillations of a pre-big bang extended very high energy density 
                         field (> 3 × 1094kg/m 3), we show that the action under the 
                         gravitational field follows a tautochrone of revolution, 
                         understood here as the primary projected geometry that 
                         alternatively replaces the Friedmann singularity in the standard 
                         big bang theory. As shown here this new approach allows us to 
                         interpret the nature of both matter and dark energy from first 
                         geometric principles.",
