cosmic censorship



  • The principle that a singularity such as a black hole is never directly visible. Black holes, e.g., are obscured by the material falling into them or by radiation or matter trapped around them Singularities are a problem area for science, and the need to explain the fact that none are seen has produced two schools of thought – censorship and the rival opinion that ‘naked’ singularities might sometimes be visible in the universe, when unusual physical effects would become apparent.
