A few questions on black holes...please describe your answers

Assuming that black holes have entropy as per hawking
then does it follow that so too would a white hole?

Would spontaneous symmetry breaking be an example of light/white body radiation?

What is the difference gravitationally between a white hole and negative matter?

Um I only am answerin to try to understand even since ya kinda explain it and yer first answer does. So where does stuff go? is it like it just disappears to never if it gets in a black hole?
Yowee this way above me.

White holes appear as part of a solution to the Einstein field equations known as the maximally extended version of the Schwarzschild metric describing an eternal black hole with no charge and no rotation. Yahoo answers might not be the best place for getting the answer you are looking for. Not many people here are familiar with Einstein's work in depth.

Yet, if you refer to Hawking it is implied that black holes and white holes are actually the same object.

The Hawking radiation from an ordinary black hole is then identified with the white hole emission.

Considering all of this is only hypothetical, it would only be possible to give you our opinion on the theories. Until science can actually prove something, these questions can not be answered.
