Creation Date Measure Based on U/Th Ratio

An astronomer at the University of Chicago has developed a new, more precise method for dating the cosmic creation event. This radiometric method also buttresses the biblical cosmic creation model by showing that all cosmic dating methods consistently produce the same cosmic creation date. The big uncertainty in the radiometric date for the birth of the universe had been the amount of uranium (U) and thorium (Th) produced by supernovae. The astronomer used measurements of the U/Th ratios in meteorites and in low-metallicity stars and population statistics of low-metallicity stars to precisely determine the U/Th ratio produced by supernovae. Armed with this data, he calculated that the cosmic creation date = 14.7±2.5 billion years, a date that is consistent with the 13.7 billion years derived from the WMAP, the Sloan Digital Sky Survey, and models of stellar burning. Moreover, his new method will soon yield radiometric dates for the cosmic creation event as good as or better than the other cosmic dating measuring tools. His research also shows that the solar system formed at the moment of maximal uranium and thorium cosmic abundance, a critical feature for the existence of advanced life.
