Friedman Equation What is pdensity.
What are the three models of geometry? k=-1, K=0, k+1
Omega=the actual density to the critical density
If we triangulate Omega, the universe in which we are in, Omegam(mass)+ Omega(a vacuum), what position geometrically, would our universe hold from the coordinates given?
I am not sure if it is proper to take such expressions of dark energy and dark matter as they are perceived in the universe and apply them to a "dynamical movement of a kind," as an expression of that Universe?
Part of that "Toposense" you might say?
***IN their figure 2. Hyperbolic space, and their comparative relation to the M.C.Escher's Circle Limit woodcut, Klebanov and Maldacena write, " but we have replaced Escher's interlocking fish with cows to remind readers of the physics joke about the spherical cow as an idealization of a real one. In anti-de Sitter/conformal theory correspondence, theorists have really found a hyperbolic cow."
