Ehia na hoku i loko o ka poe lń? I pono ua eo i kēia lā, i ka hiʻona o ka lawelawe kūkākūkā a me nā Hoʻohana o Runet hiki pinepine loaʻa i ka like nīnau / kino. IeAUPIIe, IAa IO, ka mea, ua pu ma ka manaʻo e pili ana i manao compatriots i fundamentally e maopopo i ka 'ole o ko mākou cosmic hale. Ua, pono ehia na hoku i loko o ka poe lń? He aha kekahi i hawawa, nīnau? Ia mea no ka hana o no ehia na hoku i loko o mākou Wiliau Hōkū, a me ka mea makemake e oi paakiki, a me ia mea kupono e waiho aku. Akā, i na mea a pau ka ai mea! Ke kemu i loko o ka naʻau o ka mea, oe e hele mai ma loa kamahaʻo mea. Ua huli mai ia i waena o ke kālā no haumana seriously ka ninau mea, ehia na hoku i loko o ka poe lń. A me ka ninau manawa mea,ʻaʻole e pili ana i ke kaulana ka waiʻona ma imi, a pseudoscientific theories e pili ana i ke kumu o ko ke ao nei, malihini kipa paha global kipi, akā, he nō ā ina astrophysicist.
Kuiper kāʻei, a me ka Oort ao
Inā ole a pau, a laila, heʻoiaʻiʻo nō, uaʻikeʻia ka uie kekahi hapanui hewahewa o nā poʻe i noho ma planetary haku mele 'ana o ko mākou poe lń: ano honua kahi kŘhele, hoʻokaʻawale, mai ka koena o ka asteroid kāʻei kinoea kanaka nunui Dia, hoʻopuniʻia e apo o Saturn, ka mamao Neptune, a pela aku. Ālai 'uuku kanaka, ina ia mea,ʻaʻole he kūikawā hoihoi i loko o keia kumuhana, ka mea, ua ikeia e hoʻonele Pluto mai ka Honua you. Ka mea o ia i loko o ka thousandth makahiki elua i ke kino i 'ike akula ma waho o kona Astronomical, Pluto mea i emi iki mahope o ka nui. No ka mea manawa mua mai i nā lā o kahiko Greece, ke ninau ala ae la mua astronomers: "A o ia, nae, legitimately e kapa i ka Honua?" E like me ka hopena o ka nui maliuʻia kona manaʻo ma a me ka apono ana o ka helu o nā ana hoʻohālike, Pluto i koho i ka dwarf Honua, me svezheotkrytye Eris, Sedna, a me na mea e ae. Kēia mau mea i lehulehu, a mau hamama maka o nā kānakaʻepekema hou, a nui kino. Ka mea, i kia i nā manawa aku, mai ka Sun ma mua o ka Astronomical o Neptune, a ua lilo aku ia me ka Kuiper kāʻei. Eia naʻe, hoi study ua mau komo i ka poe lń comets hoomaopopoia astronomers i kā lākou kumu - i ka Kuiper kāʻei. E like me ke kālā no manaÿo, no hoʻokahi tausani manawa hou aku, ma ke kaawale ana o kekahi malamalama makahiki o kekahi iwi kuamoʻo o ka lehulehu o ka p ÷ haku ano lani kahi. Ua ua i kona kāʻeoʻeo, a hiki aku i ka papa'āweʻaweʻa kemika intrusion i loko o ka pā ke kahahńnai o ka poe lń comets literal bombardment o e like Saturn, Mars a me ka Honua kŘhele. Presumably nā mea i loko o ka Oort ao, he lōʻihi manawa kahiko i hana ma ka Sun, akā, ma hope hoopuehu hohonu i loko o ka lewa, spinning ka manawa ma luna o ka lōʻihi ka Astronomical. Akā, i ke kumu o ka haunaele o kēia mau kino, a ke kumu no ia i kekahi manawa e hele aku hoʻi i ka lā?
Nemesis
A 'aneʻi no ka ninau e pili ana i ehia na hoku i loko o ka poe lń i waiwai ai ka mea,ʻaʻole nui, akā, he kaumaha. Ma ka hapalua like-80s ma paleontologists Jack Sepkoski a me David Raup ua haiia mai ka manaʻo i ke ola ma ka Honua ka mea i like loa, i na hoopai ana a hiki i ka nui ia'na me enviable regularity - i loko o ka 26-30 tausani makahiki. Naʻe, i nā kumu o kēia mau ia'na, paleontologists i hiki ole e hoʻouka. Ma keia kumu ka mea i hanau i ka kumumanaʻo o ka extraterrestrial kumu o catastrophes - a, e, i ka meteorite. A helu o nā kānakaʻepekema i ka lā paipai i ka Sun i i ka hoku-papalua, a mea he pōwehiwehi ulaula dwarf (no ka mea, mea nō i kekahi i kekahi), a perturbs ka Oort ao i hoakaka iaʻanuʻu, i hiki aku ai i ka cosmic bombardment o ka Honua a me ka luku aku ia a pau ke ola . Mea hypotheticalʻulaʻula dwarf ka inoa Nemesis. Ma fairness mea e e hoʻomaopopo i ka mea mahuʻi o maoli-ola nemesis i kēia mau lā hou, a hou aku nō kona nāwaliwali. Kēia ka poʻea pau i ka nele o ka pomaikai i loko o kona manaopaa, a me ka hoʻokō 'ole' e hooiaio i ka papa'āweʻaweʻa kemika bombardment, a me ka hope skepticism e pili ana i ka mana o keia mau ia'na o ke ola? Ueo ma ka Honua. Ma ka kekahi lima, loa kaulana hoku e pono i ka ia hoa. No ka laʻana, mākou kokoke galactic hoa - he aeaie hoku ano o Alpha a me Proxima Centauri. A ehia na makahiki o ka hoku, e like me ka mea, ka Astronomical puni o ka hoʻomaopopo like mawaena konu o ka umekaumaha.
