Godka madow iyo safar wakhti

Back in -1795, Pierre-Simon Laplace saadaaliyay jiritaanka xiddigaha la cufnaanta weyn iyo mass in khatarta ka imaanaya iyaga ka ma ogola in ay gudbaan by fallaaraha qorraxda ee ay u gaaraan dusha dhulka ee. Si kastaba ha ahaatee, ereyga ah sumalka uguma "godka madow" galay isticmaalka kaliya ee 1968 mahad Wheeler, laakiin ilaa waqti in loo isticmaalo magaca "star qaboojiyay" ama "collapsar".

godad Black - waa gobolka noocan oo kale ah oo meel iyo waqti, kaas oo u dhaqmo duurka ku gravitational ee sida awoodda weyn in shay kasta (xitaa dogob ray) uma baxsan karo Xaggeeda.

Sidee god madow

horumar ah ee xiddigaha sida ay mass waxay dhacdaa siyaabo kala duwan. cirbixiyeyaasha ayaa aaminsan in xiddiga-madow godka waxaa la aasaasay ka burburkii xiddigaha aad u weyn. Ugu danbayntii ayay waxay ku gubanayso hydrogen dhacdaa, markaas helium, ka dibna waxaa jira yimaado hal dhibic "x", marka khatarta of layers dusha sare mar dambe lagu dheelitiri karaa by cadaadiska gudaha iyo habka riixo miisaanka culus bilaabo. Haddii mass xiddigta waa 1.2 ilaa 2, 5 tacsida qoraxda, ka dibna qarax awood dhacaya. Inta lagu jiro musiibo ugu xiddigta la tuuraa, oo luminosity ee korodhka star ee boqolaal milyan oo jeer ka.

dillaacay Tani waa mid aad dhif u ah, sida laga soo xigtay Ugu yaraan in our Galaxy, waxa dhacaya ku saabsan boqol kasta hal sano. Waxaa jira xiddiga cusub oo aad u dhalaalaya, sidoo kale loo yaqaan "supernovaer". Si kastaba ha ahaatee, haddii ka dib markii sida qarax of mass oo ah walaxda weli waa ka weyn yahay 2.5 qoraxda, natiijada awood ciidan gravitational qaniinaa, xiddiguhuna inay tirada yar. Ka dib dhammaadka thermonuclear maaraysa xiddigtii mar dambe ma noqon kartaa in xaalad xasilooni - waxaa si buuxda Tifaftirayaasha, iyo zoo ah runtan ku darayaa indhaha geli godka madow kale. Tani waxay ifafaale waa on maskaxda saynisyahano badan.

Black Hole - Mashiinka waqti?

saynisyahano badan ayaa madaxooda iyagoo weli xoqidda ka badan, waxaa suurtagal ah ama in aadan isticmaalin godka madow safarka waqti. Qofna ma yaqaanno waxa ka baxsan this Uubo runtan. In 1935, Einstein iyo Rouzenom ayaa hypothesized in meesha la qalay a yar oo god madow laga yaabaa sidoo kale in lagugu xiro qaybta kale ee godka madow oo kale, oon la xirrira tunnel cidhiidhi ah iyada oo loo marayo goobta iyo waqtiga.

Ku saleysan aragtida this, astrophysicist Kip Thorne abuurtay geynta in la isticmaalayo a formula xisaabeed adag qeexayaa mabda'a hawlgalka iyo physics markii mishiinka. Si kastaba ha ahaatee, si ay u dhisaan portal ku meel gaar ah ee heer farsamada casriga ah, hoogtay, ma filan.

Isla mar ahaantaana, cosmologist ah oo awood leh British Stiven Hoking ayaa aaminsan in shayga qabtay godka madow ma si buuxda u baaba'aan - ay mass, tamarta lagu celiyaa caalamka ee foomka macluumaadka. Isla mar, aragtida ah asalka ah ee godadka madow Hawking noqday xal dhab ah oo duurka ku ah jaamacadaha UCLA. Haddaba, sida ay aragti cusub, godadka madow adeeco shuruucda physics galmada. aragti cusub la soo jeediyay by S. Hawking, taas oo aan la isticmaali karin godad madow in safarka ama dhaq-time in meel bannaan oo.

waan arki doonaa mishiinka waqti Kip Thorne iyo u leeyihiin in ay la aragti Stephen Hawking ee ku nool? Sida ay iyagu yidhaahdaan, waqtiga ayaa sheegi doona. Dhanka kale, waxaan qiyaasid karaa oo kaliya oo rajo ka saynisyahano cilmi cusub.
