Passage: NASA's Wilkinson Microwave Anisotropy Probe (WMAP) project's nine-year data release in 2012 estimated the age of the universe to be (13.772±0.059) ×109 years (13.772 billion years, with an uncertainty of plus or minus 59 million years). Zvisinei, zera iri rinobva pakufungidzira kwekuti chirongwa ichi chiripo chakarurama; dzimwe nzira dzekufungidzira zera renyika dzese dzinogona kupa mazera akasiyana. Kufungidzira imwezve mamiriro ezvikamu zvine hukama, semuenzaniso, kunogona kuwedzera mabara ekukanganisa kweWMAP kumanikidza nehurongwa hwehukuru. Kuyera uku kunoitwa nekushandisa nzvimbo yekutanga yekusvika kweacoustic mu microwave power spectrum kuti uone kukura kwe decoupling (kukura kwechisikwa panguva yekudzokorora kusangana).
