The black rami da kuma tafiya, ta hanyar lokaci

Back a 1795, Pierre-Simon Laplace annabta da wanzuwar taurari da wata babbar yawa da salla da cewa nauyi emanating daga gare su ba da damar auku da rana ta haskoki su isa ƙasa ta surface. Duk da haka, da astronomical Kalmar "black rami" zo a cikin yin amfani kawai a 1968 godiya ga Wheeler, amma har zuwa wannan lokaci amfani da sunan "daskararre star" ko "collapsar".

Black ramuka - wannan shi ne yankin na tsawo da kuma lokaci, a da abubuwa da gravitational filin daga irin wannan babban damar cewa babu abu (katako haske ko da) ba zai iya tserewa daga barinta ne.

Ta yaya baki rami

A ci gaba da taurari , bisa ga taro na faruwa a hanyoyi daban-daban. A ilmin Taurari yi imani da cewa star-baki rami da aka kafa a sakamakon wani rushewar sosai m taurari. Ƙarshe da ta hydrogen kona auku, sa'an nan helium, sa'an nan kuma akwai zo da wata ma'ana "x", a lokacin da nauyi na surface yadudduka iya ba a adalci da ciki matsa lamba da kuma nauyi matsawa aiwatar farawa. Idan da taro na star ne daga 1.2 zuwa 2, 5 hasken rana talakawa, sa'an nan mai iko fashewa da ya faru. A lokacin wani bala'i mafi yawan star aka jefa fitar, da kuma luminosity na star ƙaruwa a cikin daruruwan miliyoyin sau.

Wannan fashewa ne sosai rare, bisa ga A kalla a cikin galaxy, shi ya faru game da sau daya a kowace shekara ɗari. Akwai wani sabon da sosai haske star, kuma ake kira da "supernova". Duk da haka, bayan wannan idan wani fashewa da taro na abu shi ne har yanzu mafi girma daga 2.5 hasken rana, da sakamakon iko gravitational karfi compresses taurari zuwa kankanin masu girma dabam. Bayan karshen thermonuclear tafiyar matakai na star iya daina zama a Jihar kwanciyar hankali - shi ne cikakken matsa, da cosmic zoo in ji wani m idanu baki rami. Wannan sabon abu ne a kan zukatan masana kimiyya da dama.

Black Hole - wani lokaci inji?

Masana kimiyya da dama har yanzu tõno kawunansu a kan, yana yiwuwa ko ba don amfani da baki rami don lokaci tafiya. Ba wanda ya san abin da ya ta'allaka bayan wannan cosmic vortex. A 1935, Einstein da Rouzenom an hypothesized cewa wani karamin incision a baki rami iya da kyau a haɗa zuwa wani sashe na wani baki rami, game da shi, ya kafa wani kunkuntar rami ta hanyar sarari da kuma lokaci.

Bisa wannan ka'idar, astrophysicist Kip Thorne ƙirƙira da algorithm cewa ta amfani da tsaurara ilmin lissafi dabara ya bayyana manufa da aiki da lokaci inji kimiyyar lissafi. Duk da haka, don gina ta wucin gadi portal zamani fasaha matakin, alas, bai isa ba.

A lokaci guda, da iko Burtaniya cosmologist Stiven Hoking yi imanin cewa abu kama a baki rami ba bace gaba daya - da taro da makamashi da aka mayar da su zuwa sararin samaniya a cikin nau'i na bayanai. A lokacin, asali ka'idar baki ramuka Hawking ya zama real nasara a filin daga astrophysics. Yanzu, a cewar wani sabon ka'idar, black ramuka biyayya ga dokokin jimla kimiyyar lissafi. A sabon ka'idar samarwa da S. Hawking, yin shi ba zai yiwu ba a yi amfani da baki ramukan zuwa lokaci tafiya ko motsi a cikin sarari.

Za mu gani a lokaci inji Kip Thorne ko su rayu tare da Stephen Hawking ka'idar? Kamar yadda suka ce, lokaci zai gaya. A halin yanzu, za mu iya kawai yayata da kuma fatan domin sabon bincike da masana kimiyya.
