In studying galaxies of various morphological types, scientists have estimated equivalent mass-to-light ratios (M/L) of about 1-30 in solar units (1 MSUN/1 LSUN), with ratios being lower for spiral galaxies and higher for elliptical galaxies.In galaxy clusters, however, the typical total mass-to-light ratio is estimated in the range 300-600 (MSUN/LSUN).What is the implication of these numbers?
