Abaphenyi abavela eHarvard Smithsonian Center of Astrophysics (USA) okokuqala baqopha icala lokuhamba komgodi omnyama omkhulu endaweni yangaphandle. Imiphumela yomsebenzi wabo ishicilelwe kumagazini we-astrophysical iphephabhuku.
Ososayensi bake bacabanga ukuthi izimbobo ezimnyama zingahamba. Kodwa-ke, kwavela ukuthi "Ukubamba" le nto. Ngokusho kwekhanda locwaningo, uDominica Pheshe, ezimweni eziningi, izimbobo ezimnyama zihlala endaweni eyodwa ngenxa yesisindo sazo esikhulu.
Njengokuqhathaniswa, wahola isibonelo ngebhola lebhola kanye nebhola le-bowling - owesibili ukuze asuke nzima kakhulu. Ngokwesilinganiso esingaphandle "Ibhola" yinto eyizigidi ezimbalwa ezingaphezu kwelanga.
Umgodi omnyama yindawo yesikhathi esiningi ehlukaniswa amandla amakhulu amakhulu adonsela phansi ukuthi ashiye imingcele yawo awakwazi ngisho nokudanisa okuhamba ngejubane lokukhanya. Ososayensi babela izimo ezimbili ezinengqondo zokwakhiwa kwezimbobo ezimnyama:
- ukucindezelwa kwenkanyezi enkulu;
- Isikhungo sokucindezela se-Galaxy (noma i-protoclactic gesi).
Endabeni yenkanyezi, umgodi omnyama kuphela isinyathelo sokugcina sokugcina. Kwakheka lapho inkanyezi isebenzisa wonke uphethiloli we-thermonuclear futhi iqala ukuphola. Ngasikhathi sinye, ingcindezi yangaphakathi enikela ekucindezelweni ngaphansi kwethonya lamandla adonsela phansi incishisiwe. Kwesinye isikhathi lokhu kucindezelwa kuba ngokushesha kakhulu - kuya ekuweni kwengcuphe. Umgodi omnyama ungavela kwinkanyezi, isisindo sawo okungenani izikhathi ezi-3 inqwaba yelanga.
UPheshe nabanye ababambiqhaza bephrojekthi baboshwe kwizimbobo ezinkulu ezimnyama (105-1011 ilanga) iminyaka emi-5. Usayizi omkhulu womgodi enkabeni yesethi yemithala. I-Milky Way ayifani. Maphakathi ne-Galaxy yethu yi-Supermassive Black Hole Sagittarius A *, evulekile ngo-1974 irediyo yayo ayidluli ku-45 a. e., Kepha hhayi ngaphansi kwamakhilomitha angaba yizigidi eziyi-13.
Ukubuka ijubane lemithala nezimbobo ezimnyama, ososayensi bazamile ukuthola ukuthi bayalingana yini. Ama-Missets azokhombisa ukuthi noma iziphi izinguquko ezenzekile ngomgodi omnyama. Njengengxenye yocwaningo, imithala eyi-10 nezimbobo ezimnyama zafundwa e-nuclei yazo.
Ukuze kuboniswe, izinto zazingafanele kangcono kumadiski we-Accretion (ukujikeleza okujikelezayo) kwawo amanzi aqukethe. Iqiniso ngukuthi lapho amanzi ejikeleza emgodini omnyama, ugongolo lwe-radiosvel luvela, lifana ne-laser. Lapho usebenzisa indlela ye-interferometry, le misebe isiza ukukala ijubane lomgodi omnyama.
Ucwaningo luveze ukuthi omunye umgodi omnyama ovela ku-10 uvelele ngokumelene nabanye bonke abanye. Itholakala enkabeni ye-Galaxy J0437-2456 (iminyaka engama-230 elula yokukhanya evela emhlabeni). Isisindo sento singamahlandla ama-3 aphakeme kunesisindo selanga. Qinisekisa ukucabanga ngokunyakaza komgodi omnyama kutholwe ngenxa yokuqhubeka nokubona, okwenziwa e-Arecibo naseGemini Observatory. Ososayensi basungule ukuthi umgodi omnyama weSupermassive uhamba ngejubane elingamakhilomitha angaba ngu-110,000 ngehora.
Kusho ukuthini ngempela ukunyakaza kwento namanje akukaziwa. Kepha abacwaningi banokucabanga okuningana. Lokhu kungaba ukuhlanganiswa kwezimbobo ezimbili ezimnyama ezinkulu, noma into iyingxenye yohlelo oluphindwe kabili.
