They don't. No white hole has been found, it's a theoretical construct - it answers the question: 'what would happen if a black hole went back in time?' It has been theorized that they COULD be the other side of a black hole (if there is one.) White holes are like tachyons: tachyons are particles that go faster than the speed of light and can never slow down to the speed of light.

No, it does not mean that.Black holes and white holes are two different "solutions" of the equations of General Relativity; but that doesn't imply that one, or the other, actually exist. It is now almost certain that black holes exist; as for white holes, there are theoretical problems that may make them impossible, such as: * A white hole is, in many aspects, there reverse of a black hole. And just as there is no way to destroy a black hole, there is no way to CREATE a white hole. * It seems that in a white hole, entropy would decrease over time.
The existence, or possibility, of white holes has not been confirmed. Any ideas about white holes are very speculative.
Black holes have been detected (or at least evidence of their activity) White holes have never been observed, and remain theoretical for the time being.
Hypothetical celestial bodies that behave in an opposite manner to black holes and rather than pulling everything in they spit matter out. White holes also have a unstable gravity and collapse and turn into black holes.
White-holes are a theoretical hypothesis that they are the opposite of a black-hole, in which case they would push matter out into space yes.
Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.
no. but if you are worried about this, check in with a doctor just to make sure

Well first of all white holes aren't proven to exist yet so nobody knows if they pose a threat at all. Unlike black holes, white holes repel everything and spit stuff back into space, so they wouldn't really pose a threat unless they spat out a large amount of mass right at the earth.
no. white holes are actually an object predicted by scientists to exist on the other side of a black hole. it is predicted to spit out objects that entered a black hole.
