Penrose conformal diagram of Morris-Thorne wormhole
Consider the classical Morris-Thorne wormhole solution:
$$\tag{1}
ds^2 = dt^2 - dr^2 - (r^2 + a^2) \,d\Omega^2,
$$
where $a$ is a positive constant, $r > 0$ for one asymptoticaly flat spacetime, ...

How (if) can we connect a 2D "throat" piece of a wormhole to two hyperbolic 2D manifolds?
This question wad closed on the mathematics site, as it lacked clarity. So I try my luck here. My question is cosmology-inspired.
Imagine two 2D hyperbolic manifolds. I connect them by a manifold like ...

Trying to solve Einstein's Field equation , i.e Finding each components of the equation
Does knowing the $FRW$ metric equation is required first so as to solve Einstein's field equation ?
$\Rightarrow$ First FRW, then the christoffel symbols, then the riemann tensor, then the ricci ...
