Einstein’s
Field Equations
|
|
|
|
– |
Under
ideas discussed previously (cosmological
|
|
|
principle,
Weyl’s postulate, isotropy, homogeneity) the
|
|
|
field
equations reduce to the simple pair of independent
|
|
equations:
|
|
|
|
– |
R
is the scale factor, ρ is total inertial mass density of
|
|
|
matter
& radiation, p the associated pressure.
Script R
|
|
|
is
the radius of curvature, and there’s lambda.
