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.“
