Definition of Schwarzschild black hole in English:

Schwarzschild black hole

noun

Physics
  • A black hole of a kind supposed to result from the complete gravitational collapse of an electrically neutral and nonrotating body, having a physical singularity at the center 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.

    • ‘For an object with the mass of our Sun, the Schwarzschild radius is approximately three kilometres, much smaller than the Sun's current radius of about 700 000 kilometres.’
    • ‘If an object exists entirely within its Schwarzschild radius then it is referred to as a black hole.’
    • ‘If a mass is squeezed smaller than its Schwarzschild radius it becomes a Black Hole.’
    • ‘By the ‘size’ of a black hole we typically mean the Schwarzschild radius (or ‘event horizon’ as people like to say).’
    • ‘If a massive object lies entirely within its Schwarzschild radius then no light can escape from the surface of the object.’

Origin

Named after Karl Schwarzschild (1873–1916), German astronomer.
