Me aq sa dihet deri sot, shkenc\u00ebtar\u00ebt thon\u00eb se natyra na “flet” me dy gjuh\u00eb t\u00eb pakuptueshme p\u00ebr nj\u00ebra-tjetr\u00ebn. K\u00ebto dy “gjuh\u00eb” nuk merren vesh reciprokisht, nuk komunikojn\u00eb mes vete sipas parapritjes shkencore. K\u00ebshtusoj edhe shkenc\u00ebtar\u00ebt kan\u00eb v\u00ebshtir\u00ebsi t’i kuptojn\u00eb ato. Ndoshta “gjuh\u00ebt” e natyr\u00ebs dhe komunikojn\u00eb mes vete, qart\u00eb e “kristalisht”, ama p\u00ebr shkenc\u00ebn ende ka ngelur enigm\u00eb. Thelbi i gjith\u00eb k\u00ebsaj problematike “gjuh\u00ebsore” sot p\u00ebr sot \u00ebsht\u00eb graviteti misterioz. S’\u00ebsht\u00eb ekzagjerim n\u00ebse thuhet se t\u00eb gjitha problemet rreth (pa)kuptim\u00ebsis\u00eb \u00ebsht\u00eb duke i shkaktuar graviteti.<\/p>\n

Si duket natyra nj\u00eb “gjuh\u00eb” e ka rezervuar enkas p\u00ebr gravitetin, dhe nj\u00eb tjet\u00ebr “gjuh\u00eb”… p\u00ebr gjith\u00e7ka tjet\u00ebr t\u00eb universit.
\nP\u00ebr gjuh\u00ebn e par\u00eb (p\u00ebr at\u00eb t\u00eb gravitetit) fizikan\u00ebt teorizojn\u00eb duke i rrudhur supet – mir\u00ebfilli shkenc\u00ebrisht s’e kan\u00eb iden\u00eb. Tekefundit k\u00ebshtu “qahen” vet\u00eb shkenc\u00ebtar\u00ebt. Nd\u00ebrsa “gjuh\u00ebn” e dyt\u00eb, dor\u00ebn n\u00eb zem\u00ebr, dhe jan\u00eb n\u00eb gjendje ta “kuptojn\u00eb” relativisht mir\u00eb. Sa her\u00eb \u00ebsht\u00eb fjala p\u00ebr “gjuh\u00ebn” e dyt\u00eb dhe vet\u00eb shkenc\u00ebtar\u00ebt buz\u00ebqeshin m\u00eb shpesh.<\/p>\n

Fizika na m\u00ebson se ekzistojn\u00eb kat\u00ebr nd\u00ebrveprime themelore, q\u00eb jan\u00eb baza e t\u00eb gjitha bashk\u00ebveprimeve t\u00eb njohura n\u00eb natyr\u00eb. E k\u00ebto jan\u00eb forca gravitacionale, forca elektromagnetike, forca e fuqishme b\u00ebrthamore, dhe ajo e dob\u00ebta b\u00ebrthamore. Anise ka teori spekulative q\u00eb kan\u00eb propozuar madje + nj\u00eb forc\u00eb t\u00eb 5-t\u00eb (p\u00ebr t’i shpjeguar v\u00ebzhgimet e ndryshme t\u00eb \u00e7uditshme, anormale, q\u00eb nuk p\u00ebrshtaten me teorit\u00eb ekzistuese). Mir\u00ebpo neve s’na duhet, do e mohojm\u00eb t\u00eb “pest\u00ebn”, do mjaftohemi me 4 sosh.<\/p>\n

Dhe bukur, nga kjo kat\u00ebrshe del q\u00eb s\u00ebpaku p\u00ebr 3 t\u00eb fundit shkenc\u00ebtar\u00ebt e kuptojn\u00eb sadopak “gjuh\u00ebn” e universit (u mor\u00ebm vesh q\u00eb ajo e para, forca gravitacionale ngelet misterioze).
\nMe “gjuh\u00ebn e dyt\u00eb” e dim\u00eb se modeli standard i mekanik\u00ebs kuantike na thot\u00eb q\u00eb 3 forca themelore t\u00eb fizik\u00ebs nd\u00ebrmjet\u00ebsohen nga bozonet. Psh. p\u00ebr forc\u00ebn elektromagnetike si nd\u00ebrmjet\u00ebsues i kemi fotonet – elektromagnetizmi i p\u00ebrdor fotonet p\u00ebr t’i shtyr\u00eb a t\u00ebrhequr grimcat (q\u00eb zot\u00ebrojn\u00eb ngarkes\u00eb). Tutje, thuhet se bozonet W dhe Z nd\u00ebrmjet\u00ebsojn\u00eb p\u00ebr forc\u00ebn e dob\u00ebt b\u00ebrthamore. Tutje thuhet se gluonet (psh. kuarket) nd\u00ebrmjet\u00ebsojn\u00eb p\u00ebr forc\u00ebn e fuqishme b\u00ebrthamore.<\/p>\n

Bukur. Mir\u00ebpo akoma m\u00eb bukur, m\u00eb e bukura e gjith\u00eb k\u00ebsaj mrekullie \u00ebsht\u00eb se k\u00ebto 3 forca themelore t\u00eb natyr\u00ebs jan\u00eb t\u00eb “unifikuara”.
\nMe fjal\u00eb t\u00eb tjera, fizikan\u00ebt mund ta p\u00ebrshkruajn\u00eb \u00e7do event si nj\u00eb sekuenc\u00eb grimcash (dmth. cilindo event q\u00eb i p\u00ebrfshin k\u00ebto 3 forca). Edhe pse ka pafund\u00ebsisht nd\u00ebrveprime q\u00eb mund t\u00eb ndodhin (imagjino pak\u00ebz marramendjen e shp\u00ebrthimeve nukleare, ose p\u00ebrshpejtimin dhe ndeshjen e grimcave n\u00eb kushtet laboratorike me q\u00ebllim p\u00ebr t’i “p\u00ebr\u00e7ar\u00eb” ato), asgj\u00eb… no problemos, fizikan\u00ebt jan\u00eb m\u00ebsuar tashm\u00eb si b\u00ebhen parashikimet relativisht t\u00eb sakta p\u00ebr t’u dh\u00ebn\u00eb p\u00ebrpar\u00ebsi sekuencave m\u00eb t\u00eb thjeshta (q\u00eb atyre iu nevojiten p\u00ebr t’i sqaruar fenomenet).<\/p>\n

Nd\u00ebrsa, p\u00ebr fat t\u00eb keq, graviteti thjesht rebelohet kund\u00ebr ak\u00ebcilit trajtim si m\u00eb lart. Nuk i p\u00ebrfill as parashikimet, as parapritjet, e ndoshta madje as spekulimet. Si p\u00ebr inat graviteti ishte dhe ngeli ashtu kryene\u00e7, vazhdon me gjuh\u00ebn e vet t\u00eb pakuptimt\u00eb. Le q\u00eb forca gravitacionale s’m\u00ebrzitet rreth “unifikimit” me 3 forcat simotra, por dhe i p\u00eblqen t\u00eb ngelet totalisht misterioze. Hyn n\u00eb kat\u00ebrsh\u00ebn e forcave themelore t\u00eb natyr\u00ebs, ama \u00e7’e do, vazhdon me veset e veta fantomike.<\/p>\n

Ve\u00e7 e tham\u00eb m\u00eb lart, me k\u00ebt\u00eb “gjuh\u00eb” t\u00eb natyr\u00ebs shkenc\u00ebtar\u00ebt ende s’jan\u00eb mir\u00ebkuptuar, ende s’jan\u00eb n\u00eb sintoni ashtu shkenc\u00ebrisht si\u00e7 u ka hije. Tani p\u00ebr tani vet\u00ebm teorizojn\u00eb se grimca hipotetike “gravitoni” do ishte nd\u00ebrmjet\u00ebsi ideal p\u00ebr forc\u00ebn gravitacionale. Grimc\u00eb hipotetike, entitet teorik, ama n\u00ebse t\u00eb zbulohet… her\u00ebdokur, gravitoni pritet t\u00eb jet\u00eb pa mas\u00eb (ngjash\u00ebm si fotoni). Pritet t’mos ket\u00eb mas\u00eb sepse “gravitoni” vepron aty p\u00ebr aty, madje as distancat e m\u00ebdha s’i prishin pun\u00eb gravitonit.
\nOse shkurt, dmth., e qart\u00eb, po ta dinim se \u00e7’\u00ebsht\u00eb s’do ishte nevoja p\u00ebr asnj\u00eb “supozim”!<\/p>\n

E cek\u00ebm se 3 nga forcat themelore t\u00eb natyr\u00ebs ve\u00e7 jan\u00eb t\u00eb “unifikuara”. Jo se i kan\u00eb “unifikuar” shkenc\u00ebtar\u00ebt, ato ve\u00e7 ishin t\u00eb unifikuara… por dmth. dikur s’e dinim as k\u00ebt\u00eb – tashm\u00eb s\u00ebpaku dihet sigurt se jan\u00eb t\u00eb “unifikuara”.
\nImagjino tani sa bukur do ishte sikur dhe forca gravitacionale t\u00eb “unifikohej” me treshen. S’e mohon kush, do ishte ajo qershiza n\u00eb maj\u00eb t\u00eb tortes s\u00eb \u00ebmb\u00eblsis\u00eb.<\/p>\n

Andaj nj\u00eb teori e quajtur “Graviteti Kuantik” impenjohet ta ofroj\u00eb ndihm\u00ebn e vet n\u00eb k\u00ebt\u00eb drejtim. “Graviteti Kuantik” \u00ebsht\u00eb nj\u00eb term i p\u00ebrgjithsh\u00ebm p\u00ebr teorit\u00eb q\u00eb p\u00ebrpiqen ta “unifikojn\u00eb” gravitetin me forcat e tjera themelore t\u00eb fizik\u00ebs. Natyrisht, asfare e leht\u00eb… Graviteti \u00ebsht\u00eb tep\u00ebr i “ve\u00e7ant\u00eb”, tep\u00ebr misterioz.
\nJo vet\u00ebm se “gravitoni” \u00ebsht\u00eb nj\u00eb grimc\u00eb virtuale, por e qart\u00eb se gjith\u00e7ka e k\u00ebsaj teorie \u00ebsht\u00eb thjesht nj\u00eb “koncept teorik”. Madje ka dhe teorizime q\u00eb klasifikohen si “teori t\u00eb gravitetit kuantik” por q\u00eb s’kan\u00eb patjet\u00ebr nevoj\u00eb p\u00ebr “gravitonin”.
\nKjo qasje na sugjeron se jo medoemos gravitoni do duhej ta luante “rolin kryesor”. Pakashum\u00eb ngjash\u00ebm sikur t\u00eb thoshim “natyrisht q\u00eb Donald Trump \u00ebsht\u00eb Superman, ama jo medoemos duhet t’jet\u00eb Super”. Apo m\u00eb mir\u00eb t’mos e p\u00ebrmendim… pasi logjikisht do na e ngat\u00ebrronte vet\u00eb l\u00ebmshin logjik : )<\/p>\n

Teorikisht, teoricien\u00ebt s’e mohojn\u00eb q\u00eb ndoshta ka dhe Supergravitet, e kan\u00eb shpikur nj\u00eb teori enkas p\u00ebr t\u00eb. Pse jo! Pa\u00e7ka se ka ngelur dhe shum\u00e7ka p\u00ebr t’u qart\u00ebsuar rreth origjin\u00ebs s\u00eb koh\u00eb-hap\u00ebsir\u00ebs (ajnshtajniane). Gjithsesi, studiuesit e Gravitetit Kuantik (dmth. si teori e p\u00ebrgjithshme) thon\u00eb se graviteti \u00ebsht\u00eb nj\u00eb bashk\u00ebveprim kuantik. Rishtas, t\u00eb sigurt\u00eb s’jan\u00eb rreth k\u00ebtij pohimi, as q\u00eb e kan\u00eb sqaruar “sigurin\u00eb” e tyre – ama ata k\u00ebshtu pohojn\u00eb.<\/p>\n

S’ka asgj\u00eb t\u00eb keqe t\u00eb pohohet as t\u00eb teorizohet. Por ata e din\u00eb q\u00eb, madje dhe vet\u00ebm teorikisht, “Graviteti Kuantik” ballafaqohet me probleme serioze. Kjo sepse gravitacioni tani p\u00ebr tani shpjegohet p\u00ebrmes teoris\u00eb s\u00eb Relativitetit t\u00eb P\u00ebrgjithsh\u00ebm (t\u00eb Ajnshtajnit), e cilia teori p\u00ebr universin makroskopik thot\u00eb di\u00e7 krejt tjet\u00ebrfare, na “flet” p\u00ebr gj\u00ebra q\u00eb n\u00eb shkall\u00ebn mikroskopike nuk p\u00ebrputhen me ato t\u00eb mekanikes kuantike.<\/p>\n

Dihet po ashtu q\u00eb teoria e “Gravitetit Kuantik” ballafaqohet me problemin kryesor n\u00eb vetvete – me faktin q\u00eb testimet eksperimentale jan\u00eb t\u00eb pamundura. Teorit\u00eb n\u00eb k\u00ebt\u00eb drejtim k\u00ebrkojn\u00eb nivele energjitike t\u00eb paarritshme, ose t\u00eb pakap\u00ebrthyeshme me eksperimentet laboratorike. Si t\u00eb testohet bie fjala “String-teoria”, ose “Superstring-teoria”, ose “M-teoria” (sa p\u00ebr t’i p\u00ebrmendur disa sosh q\u00eb klasifikohen si “teori t\u00eb gravitetit kuantik”)? Apo ndryshorja jasht\u00ebzakonisht komplekse, e ashtuquajtur “Tuistor-teori” (p\u00ebrdoret nga disa fizikan\u00eb t\u00eb cil\u00ebve, p\u00ebr ta p\u00ebrshkruar koh\u00eb-hap\u00ebsir\u00ebn, iu p\u00eblqen t\u00eb teorizojn\u00eb “matematikisht” )?<\/p>\n

Tani p\u00ebr tani s’e ka kush iden\u00eb si t\u00eb testohen t\u00eb tilla teori! Graviteti kuantik \u00ebsht\u00eb aq misterioz, aq i pakuptuesh\u00ebm, aq i pakapsh\u00ebm, aq i paduksh\u00ebm… aq sa disa shkenc\u00ebtar\u00eb madje dyshojn\u00eb n\u00ebse ekziston apo dhe fare. Ka sa t\u00eb duash shkenc\u00ebtar\u00eb skeptik\u00eb, t\u00eb cil\u00ebt e v\u00ebjn\u00eb n\u00eb pik\u00ebpyetje ekzistenc\u00ebn e “gravitetit kuantik”. Psh. ka me dekada q\u00eb fizikani Freeman Dyson pohon se ndoshta universi vet\u00ebm shtiret si univers “dualist”, ku fusha gravitacionale (e Relativitetit t\u00eb P\u00ebrgjithsh\u00ebm) \u00ebsht\u00eb thjesht nj\u00eb fush\u00eb klasike pa “veti kuantike”, anise e gjith\u00eb materia brenda k\u00ebsaj vazhdim\u00ebsie kohore-hap\u00ebsinore kuantizohet n\u00eb grimca q\u00eb u binden rregullave t\u00eb probabilitetit.<\/p>\n

Sipas Daniel Harlow (Instituti i Teknologjis\u00eb s\u00eb Masa\u00e7usets) – “…nuk ka dhe aq kuptim t\u00eb p\u00ebrpiqesh ta kesh nj\u00eb teori n\u00eb t\u00eb cil\u00ebn graviteti \u00ebsht\u00eb klasik, nd\u00ebrsa pjesa tjet\u00ebr e fizik\u00ebs na qenka kuantike. Argumentet teorike kund\u00ebr modeleve t\u00eb p\u00ebrziera kuantike-klasike jan\u00eb t\u00eb forta (anise jo p\u00ebrfundimtare). Nga ana tjet\u00ebr, teoricien\u00ebt kan\u00eb gabuar dhe m\u00eb par\u00eb, k\u00ebshtu q\u00eb n\u00ebse mund t\u00eb testohet (n\u00ebse graviteti \u00ebsht\u00eb nj\u00eb ‘forc\u00eb kuantike’) at\u00ebher\u00eb, pse jo? N\u00ebse kjo do ua mbyllte goj\u00ebn njer\u00ebzve (t\u00eb cil\u00ebt e v\u00ebjn\u00eb n\u00eb dyshim kuantizmin e gravitetit) at\u00ebher\u00eb pse jo?”.<\/p>\n

Sidoqoft\u00eb (e cek\u00ebm dhe m\u00eb par\u00eb q\u00eb) teoricien\u00ebt e Gravitetit Kuantik as q\u00eb e v\u00ebjn\u00eb n\u00eb dyshim se graviteti \u00ebsht\u00eb bashk\u00ebveprim kuantik (i aft\u00eb p\u00ebr nxitjen e “binjak\u00ebzimit” kuantik (apo “nd\u00ebrlidhjes” – entanglement).
\nKa ngelur dhe shum\u00e7ka p\u00ebr t’u sqaruar, mbeten p\u00ebr t’i kuptuar mir\u00ebfilli dhe shum\u00eb gj\u00ebra, mir\u00ebpo mekanika kuantike duhet t\u00eb p\u00ebrfshihet n\u00eb \u00e7\u00ebshtjet e gravitetit – thon\u00eb teoricien\u00ebt. Graviteti patjet\u00ebr duhet t\u00eb jet\u00eb “kuantik”, jo “klasik”…<\/p>\n

N\u00eb rregull, ama si ta dim\u00eb. P\u00ebr fat t\u00eb keq me mjetet aktuale laboratorike eksperimentet t\u00eb “pakapshme” . Tekefundit s’mund t’i v\u00ebrtetojm\u00eb teorit\u00eb komplekse rreth e rrotull “Gravitetit Kuantik… Mir\u00ebpo s’duhet varur vetullat, kurr\u00eb s’duhet th\u00ebn\u00eb kurr\u00eb. N\u00eb v. 2018, fizikani Sougato Bose s\u00eb bashku me + 9 bashk\u00ebpun\u00ebtor\u00eb (University College, Lond\u00ebr) dhe + 2 t\u00eb tjer\u00eb (Universiteti i Oksfordit) ia b\u00ebn\u00eb t\u00eb ditur publikut nj\u00eb plan fort ambicioz. Kishin vendosur q\u00eb gravitetit kuantik t’i qasen eksperimentalisht.<\/p>\n

Anise eksperimenti i tyre mund ta “haj\u00eb” dhe nj\u00eb dekad\u00eb t\u00eb t\u00ebr\u00eb, Sougato Bose me bashk\u00ebpun\u00ebtor\u00ebt propozonin p\u00ebr nj\u00eb eksperiment i cili eventualisht do konfirmonte se graviteti \u00ebsht\u00eb nj\u00eb “forc\u00eb kuantike”. Sipas tyre \u00ebsht\u00eb e mundur q\u00eb n\u00eb kushtet laboratorike t\u00eb arrihet “graviteti kuantik” – qoft\u00eb dhe pa ditur asgj\u00eb p\u00ebr t\u00eb. Dmth. ata do i qaseshin k\u00ebsaj pune pa e zbuluar kurr\u00eb “gravitonin”, as pa e ditur \u00e7’\u00ebsht\u00eb graviteti.

Sipas “Quanta Magazine”, Miles Blencowe qenka shprehur: “M\u00eb e bukura n\u00eb k\u00ebt\u00eb argument: s’\u00ebsht\u00eb nevoja t\u00eb dihet \u00e7’\u00ebsht\u00eb teoria kuantike, e gjitha \u00e7far\u00eb k\u00ebrkohet t\u00eb besosh \u00ebsht\u00eb se duhet t\u00eb ket\u00eb nj\u00eb aspekt kuantik…”.

\nSipas “Quanta…”, eksperimenti i propozuar do p\u00ebrcaktonte n\u00ebse dy objekte (2 mikrodiamante) mund t\u00eb “binjak\u00ebzohen” kuanto-mekanikisht.

\ni supozojm\u00eb 2 kokrra t\u00eb di\u00e7kaje… ta z\u00ebm\u00eb 2 kumbulla, ato ekzistojn\u00eb lidhur n\u00eb “superpozicion”, qofshin… nj\u00ebra n\u00eb xhepin e kozmonautit n\u00eb H\u00ebn\u00eb e tjera n\u00eb xhepin ton\u00eb, nj\u00ebra kumbull\u00eb e ka vesin t\u00eb “rrotullohet” majtas, kjo n\u00ebnkupton q\u00eb shansi i “rrotullimit” t\u00eb tjetr\u00ebs do jet\u00eb djathtas (nj\u00ebkoh\u00ebsisht gjithmon\u00eb vlen dhe anasjell\u00ebza), paraprakisht shkenc\u00ebtari s’mund ta ket\u00eb iden\u00eb e rrotullimit t\u00eb grimcave ve\u00e7 e ve\u00e7, por ai \u00ebsht\u00eb i sigurt se rrotullimi i tyre n\u00eb cilindo segment t\u00eb reciprocitetit do jet\u00eb i kund\u00ebrt.<\/p>\n

Fizikani Bose dhe bashk\u00ebpun\u00ebtor\u00ebt e tij pat\u00ebn th\u00ebn\u00eb: “n\u00ebse me eksperimentin ndodh\u00eb binjak\u00ebzimi, at\u00ebher\u00eb mund t\u00eb konkludohet se graviteti \u00ebsht\u00eb i kuantizuar”. Sepse dmth, e qart\u00eb, dy objektet (2 mikrodiamantet) mund t\u00eb binjak\u00ebzohen vet\u00ebm n\u00ebse forca q\u00eb vepron mes tyre (si parapritje graviteti) \u00ebsht\u00eb nj\u00eb bashk\u00ebveprim kuantik i nd\u00ebrmjet\u00ebsuar nga gravitonet q\u00eb mund t\u00eb mbajn\u00eb superpozicione kuantike.<\/p>\n

Gjithsesi, pyetja e fundit (pakashum\u00eb si p\u00ebrmbyllje shakalogjike – Ajnshtajni dyshonte, pse t’mos jemi kureshtar\u00eb dhe ne ngapak) p\u00ebr eksperimentuesit ambicioz do ishte si vijon:
\nvall\u00eb si e dini q\u00eb dhe t\u00eb ashtuquajturit “gravitone” merren me superpozicione kuantike? \u00c7far\u00eb n\u00ebse jo! Kurr\u00eb s’i keni par\u00eb, kurr\u00eb as prekur, akoma s’i keni zbuluar, jan\u00eb vet\u00ebm grimca virtuale “gravitacionale”… t\u00eb imagjinat\u00ebs! \u00c7far\u00eb n\u00ebse “gravitoneve” (derisa t\u00eb zbulohen) u mbushet mendja ta ndryshojn\u00eb taktik\u00ebn mashtrimtare, ta p\u00ebrdorin ndonj\u00eb “\u00e7udi” totalisht t\u00eb \u00e7uditshme, akoma m\u00eb t\u00eb \u00e7uditshme sesa “binjak\u00ebzimi” : )<\/p>\n
