Deriving cosmic expansion from Einstein: The slide shows how Einstein's field equations R_μν − ½ g_μν R = 8π G_N T_μν + Λ g_μν, for a perfect fluid T_μν = −p g_μν + (p + ρ) u_μ u_ν, yield the Friedmann-Lemaître equation H² ≡ (Ṙ/R)² = 8π G_N ρ/3 − k/R² + Λ/3. Here H(t) is the Hubble parameter and Λ the cosmological constant. The equation powers models of universe evolution, helps estimate its age and density from observations, and underpins studies of dark energy with telescopes like Hubble and JWST.
