“Po, duket se di\u00e7ka mungon n\u00eb kuptimin ton\u00eb t\u00eb universit,”<\/em> shtoi Riess, nj\u00eb laureat i Nobelit n\u00eb fizik\u00eb n\u00eb vitin 2011 p\u00ebr bashk\u00ebzbulimin e zgjerimit t\u00eb p\u00ebrshpejtuar t\u00eb universit.<\/span><\/p>\n

“Kuptimi yn\u00eb p\u00ebr universin p\u00ebrmban shum\u00eb padituri p\u00ebr dy element\u00eb – materien e err\u00ebt dhe energjin\u00eb e err\u00ebt – dhe k\u00ebto p\u00ebrb\u00ebjn\u00eb 96% t\u00eb universit, k\u00ebshtu q\u00eb kjo nuk \u00ebsht\u00eb \u00e7\u00ebshtje e vog\u00ebl.”<\/em><\/span><\/p>\n

Materia e err\u00ebt, q\u00eb mendohet se p\u00ebrb\u00ebn rreth 27% t\u00eb universit, \u00ebsht\u00eb nj\u00eb form\u00eb e hipotezuar e materies q\u00eb \u00ebsht\u00eb e padukshme, por supozohet se ekziston bazuar n\u00eb efektet e saj gravitacionale n\u00eb l\u00ebnd\u00ebn e zakonshme – yjet, planet\u00ebt, h\u00ebnat, t\u00eb gjitha gj\u00ebrat n\u00eb Tok\u00eb – q\u00eb llogaritet p\u00ebr af\u00ebrsisht 5% t\u00eb universit.<\/span><\/p>\n
