The static from CSMR is used by cosmologists for ; estimating the age of the universe ( C )
Cosmologists are scientists that study the universe ( the age , evolution and possible expansion of the universe ).
A static in cosmology is the model indicating that the universe is infinite ( spatially and temporally ), this model simply suggest that the universe is neither expanding nor contrasting ), The first cosmologists suggested that the universe was static without a spatial curvature.
Therefore the static from CSMR is used by cosmologists to estimate the age of the universe since the static cosmology model of the universe was suggested by the first cosmologists.
Hence we can conclude that The static from CSMR is used by cosmologists for ; estimating the age of the universe
