Radiation kit e: te ngaro kore kē

Stiven Hoking - te cosmologist rahi me te ahupūngao ariā o to tatou wa. Fanauhia i roto i te 1942, ka anga te pūtaiao i mua nei kua i roto i te tau 20 ki te wheako raruraru hauora. Kei te kaha arai Amyotrophic sclerosis lateral mātauranga i te Tari o te Ahupūngao Mā te i Oxford, Heoi, kihai i ārai Tepene arahi i te kaha rawa, ki tonu i te takahanga ora. moea e ia i roto i 1965, ka he mema o te Royal Society i roto i 1974. I tenei wa ia kua i te tamahine, me te rua tama. I te tau 1985, mutu te pūtaiao korero. I teie mahana, i roto i tona nekeneke tinana puritia te kotahi anake uaua kanohi i runga i te paparinga. E au ra te reira i e tino immobile me tangata wahangu whiua. Heoi, i roto i te 1995 marena ano ia, a ka i roto i 2007 ... rere i roto i te weightlessness.

I te whenua, kahore he tangata kahore ona o te nekeneke, e kua e noho na ki tonu o te ora whai hua, me te ngā.

Otiia e kore e katoa te e. whanaketanga nui o Hawking ko te ariā o rua pango. Kua whakapai "te ariā o Hawking," kia rite ki te huaina ana a reira i teie nei, e rave rahi tau o ngā whakaaro pūtaiao 'e pā ana ki nga rua pango o te ao.

I te timatanga o te mahi i runga i te ariā o te ako, rite tokomaha o ana hoa, tohe ia e rua pango whakangaromia tūturu mea katoa e taka ana ki a ratou. mahue tenei lēsoni mōhiohio i te hōia, me pūtaiao katoa i runga i te ao. I whakapono te reira e tetahi āhuatanga o ngā wāhi, me te haunga o te taimaha, e kore te mea te reira.

He kua whai wāhi i roto i te ako o rua pango i roto i te 1975, i kitea Hawking e ratou emit tonu te awa o pūaho ki wāhi me etahi atu matūriki timatanga. Heoi, i whakaaro noa te kaipūtaiao ia e "Hawking radiation" he tupurangi, ohorere. pūtaiao Ingarangi tuatahi whakaaro e kore e tenei radiation kawe tetahi mōhiohio.

Heoi, ko te kounga ngingila o te ngakau - ki ruarua tonu te kaha. tonu Hawking rangahau me kitea e te whakaetonga o rua pango (arā, te radiation Hawking) ko te āhua aronui. Tenei whakahohea ia ki te faaoti e ka te mōhiohio ki te poka pango, kahore te ngaro, ka puta ke. Ko te ariā e te āhua o te poka tonu, he mea pono, ki te whakaaro tatou i te reira i te wāhi o te tirohanga o te ahupūngao kore-aronui.

I roto i te tirohanga o te ariā aronui, ki tonu te korehau te ki "mariko" matūriki e emit mara tinana rerekē. rerekē kaha marama tonu. A, no te riro te reira rawa kaha, tika i te mārua i runga i te pae hui (rohe) o BH e whanau ai takirua matūriki-antiparticle. Ki te he pai, me te rua o nga pūngao katoa o te matūriki kotahi - kino ki te mea kua hinga te matūriki ki te poka mangu, timata ratou ki te tikanga rerekē. tīmata antiparticle tōraro ki te whakaiti i te pūngao o te toenga o BH, a whangai ana te korakora pai ki te mutu-.

I runga i te wahi o tenei tukanga titiro rite te whakaetonga, e haere mai ana i te poka pango. Ko tenei whakaetonga me te huaina "Hawking radiation." Kua kitea Scientists e tenei "whakaetonga" mōhiohio fakakehei he tona wera ake, whakaaro kitea, hihinga, he tetahi pāmahana.

Kit e radiation, rite ki te pūtaiao, e whakaatu ki te meka i ngaro kore katoa ngā mōhiohio e ka riro ake i roto i te poka pango. Ko tino e ia ahupūngao aronui io te eita o te whakangaromanga oti mate o ngā mōhiohio ranei. Tenei te tikanga e taua mōhiohio, ahakoa i roto i te puka whakarerekētia, kei Hawking radiation.

Ki te he tika nga pūtaiao, e taea kia uia rite pai te mua, me te heke mai o rua mangu rite te hītori o te tahi atu aorangi.

Kia aroha mai, dismisses reira te ariā o te pea o haere i roto i te wā, me te ki atu universes te whakamahi i rua pango. Ko te aroaro o Hawking radiation te akapapu e, kua hinga tetahi ahanoa ki te poka, ka hoki ki to tatou ao i roto i te puka o te mōhiohio ke.

Ehara i kaiputaiao katoa faaite te mau ti'aturiraa o te ahupūngao Ingarangi. Heoi, wero hoki ratou e kore e kitea e ratou. I teie mahana te tatari i te ao katoa mō te tānga hou Hawking, i roto i nei i korero ai ia ki te taipitopito me te convincingly whakaū i te objectivity o ratou ao pūtaiao i roto i tahuri ariā.

Ko te atu e kua taea ki te tiki Hawking radiation i roto i te taiwhanga pūtaiao. tupu tenei i roto i te 2010
