Volume of curved space (continued) -- evaluating integrals
Intuitive ideas of volume in curved space
How to add dynamics to the RW metric: field equation
Friedmann and local energy conservation equations
How does pressure come in to energy conservation?
Calculate pressure from galaxy motions
Pressure from cosmological constant term
Rewriting Friedmann equation in terms of rho_lambda
"Dust" universe : pressure is negligible
Ignore cosmological constant too, for a while
Evolution of Hubble parameter H with time
Now get redshift vs time in terms of observable parameters........
Einstein-de Sitter model (Omega=1)
Redshift vs time for different Omega
Age of the universe from the Hubble constant, with Omega=1 and Lambda=0
Parametric form for solution when k=+/-1
