white hole
  سوراخ ِ سفید، سفید‌چال  
surâx-e sefid, sefid-câl
Fr.: trou blanc  

A hypothetical opposite of the → black hole, from which particles and light pour out. However, there is a basic problem with white holes. Contrarily to black holes, no physical processes justify their existence. The appearance of a white hole is not due to any cause, it is acausal.

See also: → white; → hole.
