For example, de Sitter’s solution for an empty universe could be written in apparently stationary form, or as an exponentially expanding solution. By 1935, the problem was solved independently by Robertson and Walker. They

A second complementary and independent approach involves studies of the CMB, both for understanding the origin of the light elements and its consequences for determining the b

Claudia Fisher-Buttinger,Christine Vallasterese models can account for the observations, particularly the limits imposed in the early 1980s on the amplitude of temperature fluctuations in the CMB. Something was seriously missing—more than simply baryons are needed to account for the observations.
