Gadiem ilgi zin\u0101tnieki ir spekul\u0113ju\u0161i par Zemes likteni – pateicoties progres\u012bvajiem p\u0113t\u012bjumiem un superdatoru simul\u0101cij\u0101m, tagad mums ir skaidr\u0101ks priek\u0161stats par to, k\u0101 var\u0113tu izv\u0113rsties m\u016bsu plan\u0113tas n\u0101kotne un kad ir sagaid\u0101ms pasaules gals, raksta \u201cThe Daily Galaxy\u201d.<\/p>\n
Nesen veikts p\u0113t\u012bjums, ko veica NASA kop\u0101 ar Toho Universit\u0101ti Jap\u0101n\u0101, sniedz p\u0101rsteidzo\u0161as prognozes.<\/p>\n
Izmantojot sare\u017e\u0123\u012btus mode\u013cus, zin\u0101tnieki ir lab\u0101k izpratu\u0161i mijiedarb\u012bbu starp Zemes atmosf\u0113ru, Saules starojumu un neizb\u0113gamo Saules izple\u0161anos, kas ir \u013c\u0101vis noteikt, cik daudz laika mums paties\u012bb\u0101 ir atlicis, pirms Zeme k\u013c\u016bs neapdz\u012bvojama, un ko tas noz\u012bm\u0113 cilv\u0113ces n\u0101kotnei.<\/p>\n

Zin\u0101tniekiem jau sen bija skaidrs, ka Saule k\u0101du dienu p\u0101rv\u0113rt\u012bsies par sarkanu milzi, izplet\u012bsies izm\u0113ros un k\u013c\u016bs daudz spo\u017e\u0101ka. \u0160is process s\u0101ksies p\u0113c vair\u0101kiem miljardiem gadu, ta\u010du izmai\u0146as, kas notiek pirms t\u0101, padar\u012bs dz\u012bv\u012bbu uz Zemes neiesp\u0113jamu jau krietni \u0101tr\u0101k.<\/p>\n
