what is black , white and worm holes
Answers
Answer:
Schwarzschild wormhole
The complete Schwarzschild geometry consists of a black hole, a white hole, and two Universes connected at their horizons by a wormhole. The negative square root solution inside the horizon represents a whitehole. A white hole is a black hole running backwards in time.

Answer:
Black Holes- black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
White holes-in general relativity, a white hole is a hypothetical region of spacetime and singularity which cannot be entered from the outside, although energy-matter, light and information can escape from it. In this sense, it is the reverse of a black hole, which can be entered only from the outside and from which energy-matter, light and information cannot escape. White holes appear in the theory of eternal black holes. In addition to a black hole region in the future, such a solution of the Einstein field equations has a white hole region in its past.[1] However, this region does not exist for black holes that have formed through gravitational collapse, nor are there any observed physical processes through which a white hole could be formed.
Worm holes-A wormhole can be visualized as a tunnel with two ends at separate points in spacetime (i.e., different locations, or different points in time, or both).
