I’ve often wondered, if the the universe is expanding from the initial big bang, does that mean that there is a far edge and beyond that nothing exists yet?

With a little effort and a TI calculator, maybe you can get some clue to the answer using Albert's equation to solve for the appropriate metric tensor:

R_μν - 1/2g_μνR + g_μνΛ = 8 π G/c⁴T_μν

Where:
R_μν==>Ricci Tensor (Derived from Riemann Tensor)
g==>Metric Tensor
R==>Ricci Curvature Scalar (Derived from Ricci Tensor)
Λ==>lambda = Universal Constant (Expansion/Dark Energy)
π ==> PI (8 decimal places is OK)...
G==>Gravitational Constant
c==>Speed of Light
T==>Stress-Energy Momentum Tensor 😲
