white hole

The reverse of a black hole: a region where matter spontaneously appears. Early calculations on black holes indicated that the extreme distortion of space and time inside the event horizon should connect our Universe with another through an Einstein–Rosen bridge (or wormhole). Matter falling into the black hole should then correspondingly appear in the other Universe as outpouring of material through a white hole. It now seems likely that such links, and hence white holes, do not exist.
