'''Lubang hirang''' ({{Lang-en|black hole}}) adalah bagian matan ruang waktu nang marupakan gravitasi nang takuat pada nang lain, cahaya gin kada kawa bukah matan lubang hirang. Teori relativitas umum mamparkiraakan bahwa parlu massa nang ganal gasan maulah sabuting '''lubang hirang''' nang baandak di ruang waktu.<ref name="wald 1997">{{cite book |last=Wald |first=R.

Suhu ngini babanding tabalik lawan massa lubang hirang, jadinya ngalih amum handak maitihi lubang hirang bamassa bintang atawa labih. Lubang hirang tabagi manjadi 4: lubang hirang bamassa manangah, lubang hirang primordial, lubang hiranh bintang, wan lubang hirang supermasif nang rancak banar ada di pusat sabuting galaksi.<ref>{{Cite web|date=2018-09-21|title=Black Holes, Explained|url=https://www.nationalgeographic.com/science/space/universe/black-holes/|website=Science|language=en|access-date=2020-09-29}}</ref>
