N\u00ebse dikush q\u00eb udh\u00ebton n\u00eb koh\u00eb do t\u00eb kthehej pas dhe do t\u00eb takonte gjysh\u00ebrit, a do ta parandalonte lindjen e tij?

Nj\u00eb grup shkenc\u00ebtar\u00ebsh ka krijuar, p\u00ebr her\u00eb t\u00eb par\u00eb, nj\u00eb simulim, me an\u00eb t\u00eb t\u00eb cilit do t\u00eb mund t\u00eb shohin si mund t\u00eb nd\u00ebrveprojn\u00eb dy fotone q\u00eb udh\u00ebtojn\u00eb n\u00eb koh\u00eb.

N\u00eb simulim, k\u00ebrkuesit ekzaminuan dy rezultate t\u00eb mundshme p\u00ebr nj\u00eb foton q\u00eb udh\u00ebton n\u00eb koh\u00eb.

Koha dhe hap\u00ebsira mund t\u00eb p\u00ebrkulen dhe t\u00eb shformohen. Nevojitet nj\u00eb sasi e madhe materieje dhe energjie, p\u00ebr t\u00eb krijuar shformime t\u00eb tilla, por teorikisht, ato jan\u00eb t\u00eb mundura.
