E nj\u00ebjta pyetje \u00ebsht\u00eb dhe \u201cfrik\u00eb\u201d, Discovery na thot\u00eb se shkenca e paska mund\u00ebsin\u00eb p\u00ebr \u201cv\u00ebrtetim\u201d mir\u00ebpo q\u00ebllimisht u anashkaluaka v\u00ebrtetimi.

Thuase don\u00eb t\u2019na thon\u00eb: m\u00eb mir\u00eb hipoteza e nj\u00eb Dick-u t\u00eb s\u00eb kaluar\u00ebs t\u00eb ngelet \u201cmarr\u00ebzi\u201d, sesa t\u2019na shembet realja si\u00e7 e njohim, bota e shkencave dhe ajo e imagjinat\u00ebs.<\/p>\n

Discovery sikur na sugjeron q\u00eb disa gj\u00ebra m\u00eb mir\u00eb t\u2019mos i dim\u00eb kurr\u00eb. Ndoshta thjesht sa m\u00eb shum\u00eb teori, sa m\u00eb shum\u00eb hipoteza, sa m\u00eb shum\u00eb artikuj e revistash shkencore, nj\u00eb oqean teorik, dhe sa m\u00eb shum\u00eb entuzias\u00ebm. P\u00ebrndryshe, n\u00ebse t\u2019v\u00ebrtetohej se jemi krijesa simulative, holograme biologjike, \u201csimulacione\u201d t\u00eb ndokujt tjet\u00ebr, mbase tutje s\u2019do na nevojiteshin as dijet as shkencat, do \u00e7oroditej ai kodi virtual i \u00ebndrrave tona, do shembej i gjith\u00eb qielli holografik, do ishte di\u00e7 si \u201cp\u00ebrmbysje zhg\u00ebnjimtare\u201d e universit humanist\u2026<\/p>\n

<\/p>\n

Bazuar n\u00eb entuziasmin e Quanta, sikur na imponohet t\u00eb zgjedhim mes 2 \u201cp\u00ebrfundimeve\u201d konkluzive. 1) Duhet pranuar se teoria e Philip K. Dick paska qen\u00eb (dhe dmth. ende \u00ebsht\u00eb) mund\u00ebsi e v\u00ebrtet\u00eb, e mundshme, fare leht\u00eb t\u00eb vuloset me shkenc\u00ebn e mir\u00ebfillt\u00eb. 2) E qart\u00eb se \u201centuziasmi shkencor\u201d sot p\u00ebr sot \u00ebsht\u00eb duke na u rritur e zgjeruar jasht\u00eb mase, ndoshta m\u00eb \u201cgjer\u00ebsisht\u201d se zgjerimi i vet\u00eb universit.

Natyrisht, si opsion i p\u00ebrhersh\u00ebm, si opsion \u201ckonstant\u201d, na ngelet dhe buz\u00ebqeshja : ) E megjithat\u00eb, ja q\u00eb kemi shkuar aq \u201clarg\u201d, nj\u00eb simulacion kompjuterik dhe voila, do ta zb\u00ebrthejm\u00eb \u201ckoh\u00ebn\u201d dhe \u201chap\u00ebsir\u00ebn\u201d, qoft\u00eb ndaras a qoft\u00eb s\u00eb bashku, si \u201cmodel\u201d ajnshtajnian. Duke e sqaruar koh\u00eb-hapesir\u00ebn do jemi aq af\u00ebr, mbase do e kapim dhe gravitein p\u00ebr \u201cbishti\u201d. Q\u00ebkur koh\u00eb-hapesira ajnshtajniane ka kuptim vet\u00ebm si e lidhur me misterin e gravitetit. Q\u00ebkur s\u2019mund t\u2019ket\u00eb as \u201cvrim\u00ebzeza\u201d pa gravitetin, q\u00ebkur ky i dyti \u00ebsht\u00eb shkaktari i t\u00eb par\u00ebs. E kape bishtin dtth. e ke kapur dhe dhelpr\u00ebn.<\/p>\n

Shkurt, si fillim i p\u00ebrmbylljes, pritet ta sqarojm\u00eb \u201ckoh\u00eb-hap\u00ebsir\u00ebn\u201d ajnshtajniane, jo se na ngutet me entuziasmin por sepse kaloi nj\u00eb shekull nga profecia e plakut. Pastaj pak ngelet, t\u00eb tjerat pothuaj vetiu do qart\u00ebsohen, sepse gj\u00ebrat t\u00eb \u201clidhura\u201d.
