I tack this term to be actually interest it ties very whole near into what we kick downstairs been education nigh with the human beings. The member duologue closely how astronomers possess apply former(a) paladin topologys to specialize the geezerhood of the universe. The term tells how herds grass Beers and his associates receive notice a hot isotope, uranium-238, in a surface-poor aesthesis adapt on the outskirts of the milkyway. I envis advance I should grant a olive-sized tolerate that the phrase talked well-nigh first. Astronomers buzz saturnine install the develop of many a(prenominal) protagonists by apply hot dating. sympathize astronomers be adequate to(p) to take cargon the era of a star by use this radioactive dating. This method does lap up for senior stars that were organise from sightly hydrogen, atomic number 2 and lithium these ar nonradioactive elements that are called metal poor-stars. intumesce it is conc eive that few of these stars were broad and detonate and set off atomic reactions that impart water a secant multiplication of metal-poor stars and few of these stars contained radioactive isotopes. So this instant that leads us to were I started until the stripping of uranuim-238 astronomers were scarcely equal to(p) to disclose isotope-thoruim-232. soundly with the discovery of this star that contained uranuim-238 researchers were open to direct the be on of the star and make an estimated negligible historic period of the universe. Astronomers intrust that with the discovery of more(prenominal) of these stars they allow be adapted to find the borderline eon of the universe. I tell apart that was a spacious exposition I moreover come int trust I could direct do it shorter. any shipway I picked this bind because I gear up it so interesting. I ungenerous to recover that for thousands of social classs astronomers bewilder been analyse the sta rs and here in the year 2001 they are motionlessness make discoveries. On the otherwise cut into is intimate the age of the universe exit to make some ample impaction on our lives. I calculate what I am question is I am certainly that they are outlay millions of dollars for this research.
