SUMMARY

White holes are theoretical constructs that serve as the opposite of black holes, functioning as time reversals that eject matter instead of absorbing it. They arise as solutions to Einstein's equations of general relativity and are considered to exist only under ideal conditions. The concept suggests that if matter survives a black hole, it could potentially be expelled through a white hole into another universe. Current understanding of white holes remains limited due to their purely theoretical nature.

PREREQUISITES
  • Understanding of Einstein's equations of general relativity
  • Familiarity with the concepts of black holes and event horizons
  • Basic knowledge of theoretical physics
  • Awareness of cosmological theories regarding the universe
NEXT STEPS
  • Research the implications of Einstein's equations on black and white holes
  • Explore the concept of event horizons in greater detail
  • Study the theoretical frameworks surrounding multiverse theories
  • Investigate current scientific perspectives on the existence of white holes
USEFUL FOR

Astronomers, physicists, and students of theoretical physics interested in the concepts of black holes, white holes, and the fundamental laws of the universe.

what r white holes

White holes are the opposite of black holes...or maybe they are the same:

see

http://en.wikipedia.org/wiki/White_Holes

If anything survives getting sucked into a black hole it might be ejected at a distant white hole end and into another universe...
 
White holes are basically theoretical anti-black holes- meaning, they are a time reversal of the black hole and eject any matter that has crossed into the event horizon.

The reason we really don't know a lot about them is that they are purely theoretical- they only arise as a solution to one of Einstein's equations, and can only exist under ideal conditions.
