Prie\u0161 kiek daugiau nei trejus metus danguje pasirod\u0117 keistas objektas 2017 m. Objektas, pavadintas 'Oumuamua, suskald\u0117 astronom\u0173 bendruomen\u0119 ir suk\u0117l\u0117 diskusij\u0173 d\u0117l jo prigimties.<\/p>\n\n\n\n

Viena tyr\u0117j\u0173 grup\u0117 teigia, kad tarp\u017evaig\u017edinis k\u016bnas atsirado i\u0161silaisvinus i\u0161 kitos planetos gravitacinio lauko, o kiti teigia, kad galb\u016bt tai gali b\u016bti ateivi\u0173 laivas, nes jo savyb\u0117s labai skiriasi nuo vis\u0173 jau matyt\u0173.<\/p>\n\n\n\n

Kuri teorija yra teisinga, lieka neai\u0161ku.<\/p>\n\n\n\n

Viename podkasto \"Joe Rogan Experience\" epizode teorin\u0117s fizikos specialistas, Harvardo universiteto profesorius Avi Loebas kalb\u0117josi su amerikie\u010di\u0173 komiku ir podkasto ved\u0117ju Joe Roganu, gindamas ateivi\u0173 laiv\u0173 teorij\u0105.<\/p>\n\n\n\n

Joe Rogano podkaste Loebas paai\u0161kino ir aptar\u0117, kas j\u012f paskatino padaryti toki\u0105 i\u0161vad\u0105.<\/p>\n\n\n\n

\"Kaip ir \u0160erlokas Holmsas, seku \u012frodymais ir bandau rasti sprendim\u0105\", - sako Loebas, podkasto ved\u0117jo paklaustas apie 2020 m., kuriuos u\u017ekariavo Oumuamua polemika.<\/p>\n\n\n\n

\u0160is tarp\u017evaig\u017edinis k\u016bnas buvo pirmasis Saul\u0117s sistemai nepriklausantis k\u016bnas, apsilank\u0119s m\u016bs\u0173 apylink\u0117se.<\/p>\n\n\n\n

I\u0161 prad\u017ei\u0173 astronomai man\u0117, kad tai gali b\u016bti kita kometa ar asteroidas. Ta\u010diau 'Oumuamua charakteristikos neatitiko komet\u0173 ir asteroid\u0173 parametr\u0173.<\/p>\n\n\n\n

Loebas ai\u0161kina, kad \"Oumuamua\" nebuvo \u012fprastas objektas, jis tur\u0117jo tam tikr\u0173 anomalij\u0173, tam tikr\u0173 savybi\u0173, kurios nebuvo pana\u0161ios \u012f kitus jau matytus \u012fprastus kosminius objektus.<\/p>\n\n\n\n

Kadangi \u012fprastos kometos atkeliauja i\u0161 Saul\u0117s sistemos pakra\u0161\u010di\u0173, kitos \u017evaig\u017ed\u0117s taip pat turi (ar bent jau tur\u0117t\u0173 tur\u0117ti) savo kometas. Be to, \u0161ie komet\u0173 gabalai periferijoje yra silpnai suri\u0161ti, tod\u0117l gali lengvai pab\u0117gti nuo savo \u017evaig\u017ed\u0117s \u0161eiminink\u0117s ir keliauti \u012fvairiomis kryptimis.<\/p>\n\n\n\n

D\u017eo Roganui Loebas paai\u0161kino, kad Oumuamua yra kometa: \"Kometos - tai ledu padengtos uolienos, kai jos priart\u0117ja prie Saul\u0117s, j\u0173 pavir\u0161ius \u012fkaista ir ledas virsta garais, o u\u017e j\u0173 matoma gra\u017ei kometos uodega... Tuo tarpu asteroidai yra tiesiog uolienos, ant kuri\u0173 n\u0117ra daug ledo.\"<\/p>\n\n\n\n

Buvo sunku pasakyti, kad 'Oumuamua buvo kometa, nes nebuvo jokios kometos uodegos.<\/p>\n\n\n\n

Be kometos uodegos nebuvimo, buvo dar viena ne\u012fprasta savyb\u0117, kurios \u012fprastin\u0117 astronomija negal\u0117jo paai\u0161kinti:<\/p>\n\n\n\n

Tarp\u017evaig\u017edinis k\u016bnas 'Oumuamua tur\u0117jo papildom\u0105 post\u016bm\u012f kelyje nuo Saul\u0117s.<\/p>\n\n\n\n

Loebas ai\u0161kina, kad \u0161\u012f papildom\u0105 post\u016bm\u012f paprastai sukelia kometos uodega.<\/p>\n\n\n\n

Ledo garavimo procesas (kaip ir raketos kuro deginimas) suteikia papildom\u0105 post\u016bm\u012f uoliniam objektui \u012f prie\u0161ing\u0105 pus\u0119, ta\u010diau 'Oumuamua netur\u0117jo jokios kometin\u0117s uodegos, tad i\u0161 kur atsirado papildomas post\u016bmis?<\/p>\n\n\n\n

Loebas su Joe Roganu pasidalijo mintimis, kad tuo metu jis prad\u0117jo galvoti, jog Oumuamua gal\u0117jo b\u016bti ne kometa ar asteroidas, o kas nors kita, pavyzd\u017eiui, ateivi\u0173 laivas.<\/p>\n\n\n\n

Be to, dar viena keista tarp\u017evaig\u017edinio objekto savyb\u0117 buvo jo ry\u0161kumas.<\/p>\n\n\n\n

'Oumuamua ry\u0161kumas pakeit\u0117 saul\u0117s \u0161viesos atspind\u012f de\u0161imt kart\u0173, o tai gal\u0117t\u0173 reik\u0161ti tam tikr\u0105 geometrin\u012f format\u0105.<\/p>\n\n\n\n

\"Pagalvokite apie labai plon\u0105 popieriaus lap\u0105, kuris krenta v\u0117jyje ir kei\u010dia m\u016bs\u0173 matom\u0105 plot\u0105. De\u0161imteriopai pasikei\u010dia to popieriaus lapo projekcinis plotas, kai \u012f j\u012f \u017ei\u016brime. B\u016btent toki\u0105 i\u0161vad\u0105 padar\u0117me i\u0161 \u0161io objekto, besisukan\u010dio kas a\u0161tuonias valandas\", - apie keist\u0105 tarp\u017evaig\u017edinio objekto ry\u0161kum\u0105 pasakojo Loebas.<\/p>\n\n\n\n

\u0160is veiksnys leido daryti i\u0161vad\u0105, kad 'Oumuamua tikriausiai turi specifin\u0119 geometrin\u0119 form\u0105 ir grei\u010diausiai yra plok\u0161\u010dia, kaip popieriaus lapas.<\/p>\n\n\n\n

\"Tarp\u017evaig\u017edinio<\/a><\/figure>\n\n\n\n

Apibendrinant visus pirmiau pateiktus duomenis, nustatyta, kad tarp\u017evaig\u017ediniame objekte n\u0117ra dulki\u0173, duj\u0173 ar kit\u0173 med\u017eiag\u0173, kurios gal\u0117t\u0173 paai\u0161kinti papildom\u0105 post\u016bm\u012f. Be to, jis buvo ne\u012fprasto ry\u0161kumo, kur\u012f l\u0117m\u0117 jo forma.<\/p>\n\n\n\n

Loebas ir jo komanda dom\u0117josi, kuo b\u016bt\u0173 galima paai\u0161kinti visas \u0161ias ypatingas savybes.<\/p>\n\n\n\n

Savo ruo\u017etu jie i\u0161k\u0117l\u0117 teorij\u0105, kad galb\u016bt tarp\u017evaig\u017edin\u012f objekt\u0105 stumia jo pavir\u0161iuje atsispindinti saul\u0117s \u0161viesa. Kaip \"pardavim\u0105 stumia v\u0117jas, taip ir plon\u0105 objekt\u0105 galima stumti \u0161viesa, tai vadinama \u0161viesos bur\u0117mis, ir mes i\u0161 tikr\u0173j\u0173 dabar naudojame \u0161i\u0105 technologij\u0105, kurdami j\u0105 kosmoso tyrimams\", - sako Loebas D\u017eo Roganui.<\/p>\n\n\n\n

Be viso to, 'Oumuamua greitis buvo labai ne\u012fprastas.<\/p>\n\n\n\n

Kosminis objektas buvo toks greitas, kad astronomai negal\u0117jo sugalvoti, kaip j\u012f persekioti ir surinkti daugiau informacijos.<\/p>\n\n\n\n

Palyginti su i\u0161 \u017dem\u0117s paleistomis raketomis, 'Oumuamua buvo nepaprastai greitesn\u0117, tod\u0117l astronomai atmet\u0117 galimyb\u0119, kad tai gal\u0117jo b\u016bti \u017dem\u0117s kilm\u0117s technologija. <\/p>\n\n\n\n

Surink\u0119 vis\u0105 i\u0161 kosminio objekto surinkt\u0105 informacij\u0105, Loebas ir jo komanda pri\u0117jo prie i\u0161vados, kad galb\u016bt \u0161is objektas gali priklausyti kitai civilizacijai, dar \u017einomai kaip ateiviai. <\/p>\n\n\n\n

\u0160i i\u0161vada suk\u0117l\u0117 daug nesutarim\u0173 tarp astronom\u0173, tod\u0117l 2020 m. prasid\u0117jo diskusijos apie \u0161\u012f keist\u0105 objekt\u0105, kuris danguje pasirod\u0117 2017 m. <\/p>\n\n\n\n

Ar Oumuamua priklauso ateiviams, ar ne, galb\u016bt mums prireiks de\u0161imtme\u010di\u0173, kad tai su\u017einotume. O gal niekada nesu\u017einosime, tik laikas parodys.<\/p>\n\n\n\n

Vis d\u0117lto, remiantis Loebo tyrimais, 'Oumuamua nebuvo atsi\u0173stas \u012f m\u016bs\u0173 Saul\u0117s sistem\u0105 ateivi\u0173, kad \u0161nipin\u0117t\u0173 \u017dem\u0119.<\/p>\n\n\n\n

Galb\u016bt tai buvo tik svetim\u0173 laiv\u0173 technologija, kuri nety\u010dia pasiklydo, kaip kosmoso \u0161iuk\u0161l\u0117s.<\/p>\n\n\n\n

Galiausiai, i\u0161 to, kas pasakyta, turime suprasti, kad visi tur\u0117tume b\u016bti atviri ir m\u0105styti apie visas galimybes, \u012fskaitant ir apie gyvyb\u0119 u\u017e m\u016bs\u0173 Saul\u0117s sistemos rib\u0173.<\/p>\n\n\n\n
