Very interesting report showing how detailed spectroscopic work can be done concerning stars and their chemical composition. The report said:
"Further analysis showed that the stars seem to be made of unusual ingredients given their segment of the galaxy. The bands of light that reached Earth suggested that at least the 27 brightest stars in the cluster had unusually low metal content, indicating that the material that produced them came from outside the Milky Way."
Nothing in the report shows Einstein Special Relativity is wrong or that the chemical composition of distant stars cannot be determined. The explanation of *low metal content* is based upon stellar evolution and p-p chain fusion in the stars as well as Big Bang, primordial gas cloud composition.--Rod
