Difference between black hole solutions and wormhole solutions

Click For Summary
SUMMARY

The discussion clarifies the distinction between black hole solutions and wormhole solutions, specifically referencing the Schwarzschild wormhole within the context of general relativity. It highlights that the maximally extended Schwarzschild solution can be analyzed using a Kruskal diagram, which effectively differentiates between black holes and white holes. Furthermore, it is established that while Schwarzschild wormholes exist theoretically, they cannot be traversed due to the presence of a singularity, and traversable wormholes necessitate exotic matter.

PREREQUISITES
  • Understanding of general relativity concepts
  • Familiarity with Schwarzschild solutions
  • Knowledge of Kruskal-Szekeres coordinates
  • Basic principles of exotic matter in theoretical physics
NEXT STEPS
  • Research Kruskal diagram applications in general relativity
  • Explore the properties of traversable wormholes
  • Study the implications of exotic matter on wormhole stability
  • Examine the differences between black holes and white holes in detail
USEFUL FOR

The discussion is beneficial for theoretical physicists, astrophysicists, and students studying general relativity, particularly those interested in black hole and wormhole dynamics.

How do we know which one is a black hole solution(metric) or a wormhole solution(metric)? what is its feature?

Are you talking about Schwarzschild wormholes in particular? In the maximally extended Schwarzschild solution, the region represented by the black hole can easily be differentiated from the region represented by the so called white hole through a Kruskal diagram: http://en.wikipedia.org/wiki/Kruskal–Szekeres_coordinates
 
I'm not quite sure what the OP wants. Just in case, I should point out that you can't actually traverse the Schwarzschild wormhole, the singularity gets in the way. There are such things as traversable wormholes, but they generally require exotic matter.
