Scientists can calculate only the age of cluster of stars as a whole. Now since, Methuselah is not from our galaxy and hence its original cluster is different from its present cluster, this contradiction is arising. Computer models developed to determine the age of stars of one cluster cannot be used to determine the age of stars of another cluster. So the basic problem here is that this star is now in a completely different cluster and scientists needs to find various others factors such as its original cluster and the age at which it entered into our system to determine its actual age. All in all its a balance between Scientific facts and technical assumptions.Ashish Rathorehttps://www.blogger.com/profile/07126866412951257297noreply@blogger.comtag:blogger.com,1999:blog-6399467271056583410.post-82783875238028277052014-01-10T10:44:53.645+01:002014-01-10T10:44:53.645+01:00Read the same paper fully Thom, it has been given ...Read the same paper fully Thom, it has been given "Employing modern theoretical isochrones, which include effects of helium diffusion, revised nuclear reaction rates, and enhanced oxygen abundance, we use the precise distance to infer an age of 14.46 ± 0.31 Gyr".<br />Everybody is sure that nothing can be older than universe itself and that's what i have explained in my end para.
