Schwarzschild black hole

Pronunciation: /ˈʃvɑːtsˌʃiːlt/
Pronunciation: /ˈʃwɔːtsˌtʃʌɪld/


A black hole of a kind supposed to result from the complete gravitational collapse of an electrically neutral and non-rotating body, having a physical singularity at the centre to which infalling matter inevitably proceeds and at which the curvature of space-time is infinite. A Schwarzschild radius is the radius of the boundary of a hole of this type.
Example sentences

  • By the ‘size’ of a black hole we typically mean the Schwarzschild radius (or ‘event horizon’ as people like to say).
  • If an object exists entirely within its Schwarzschild radius then it is referred to as a black hole.
