Question

What if I COLLIDE BLACK HOLE AND WHITE HOLE??WILL IT CREATE A WORMHOLE???

Answer 1

Heya...Empress Here...

> As you know that Black holes eat up matter and white spit up. And acc. to me when both collide a wormhole won't be taking place.

• The black hole, having a much higher gravitational pull and density, will eat up the white hole itself resulting in explosions are the "death" of the white hole.

Answer 2

collison of this two holes is just like collison of matter and antimatter.
 collision of a small wormhole with a black hole. wormhole spacetime severely distorts the black hole event horizon and then is destroyed at the singularity. if a blackhole enters a wormhole, the most probably this is what will happen :

The blackhole will bend up the already bent space time structure of space time will lead to extreme bending and creation of new space or matter wil result this high bending will lead to severe implications. a white hole is an area of spacetime or universe where nothing could enter from the outside, or mathematically thinking, it is a maximum extension of a black hole 

by the way A non-spinning, equally massive black hole and white hole experience a direct collision.say physicist but i think it is wrong

Mathematically it is a black hole under inverted time. This can be interpreted as a black hole in an universe where second law of thermodynamics is inverted, that is the entropy always decreases

Since second law of thermodynamics has probablistic nature, one can see a white hole as a highly unimaginable state of black hole: the state where it consumes high-entropy Hawking radiation and exhales low-entropy objects instead of doing the vice versa

consider collisions between objects which have opposite arrows of time it is usually derived that upon such collision the object with reverse time arrow will quickly switch its time direction for which only a microscopic perturbation is enough. This means that in a hypothetical cosmos where there is a black and a white hole, in a small time after their first interaction the white hole will become another black hole so that the system will end up with a massive black holes.

It should be cleared that in the universe there is no difference between a black and a white hole, the both behave the same: consume and radiate high-entropy radiation and always increases entropy
