2nd piece of evidence to support the big bang theory
nebula (dust, gas, H) - Protostar (H-He) - Main Sequence (Gravity, fusion) - Red giant (He-C,fe) - White dwarf (He-C) - Black dwarf (nothing)

nebula (dust, gas, H) - Protostar (H-he) - Main sequence (Gravity, fusion) - Supergiant (H-He-c,fe) - Neutron star (fe) -or- black hole (fe)
