white holes
Cosmic matter fountains
White holes are hypothetical objects in physics—the theoretical opposite of black holes.
Where black holes pull matter in and allow nothing to escape, white holes would expel matter and energy while preventing anything from entering.
They emerge from equations in general relativity but have never been observed, and most physicists doubt they exist in nature.
