Question

What exactly is a WHITE-HOLE?
And can a worm-hole be real? If so,what could be the pros and cons?
P.S-I tried to research and stuff,but it was a bit confusing. Answer in the best and the easiest way!
No spams!
P.P.S--->A HAPPY NEW YEAR,TO ALL OF YA EARTHLINGS! (In advance,ofcourse. :P)

Answer 1

HOWDY MATE.

It is Just like Black Holes and Wormholes.

Difference between 'em

1】Black hole is an area in space whose' gravitational force is that tense that nothin' can escape,not even light its pull.It is one of the biggest mysteries that what is inside a black hole.

2】Wormholes is a link between two massively apart points in "Space-time",simply it is a tunnel between two Points or Galaxies.It is not known that whether we can reach the other the end as it could collapse suddenly.

3】Comin' to main stuff .
White holes,It is just reverse of Blackholes.Nothin can enter it although matter and light can escape it.It is like a one way ticket to nowhere.Whiteholes can be created through many physical processes.
The 2006 GRB 060614 had been proposed as first documented occurrence of white holes.

EDIT FOLKS'

Pros):

1)It can constitute a major portion of Mysterious dark matter from which 95% of the known Universe is made of.
2) Researchers say that it can even predate The Big Bang.
3)When black holes die they can transform into a White hole.

Cons):
1)Nothing can enter into its event horizon so we don't know what really is inside it.
2)It would take a Black hole a mass of quadrillion times of that of sun to convert Universe into a White hole.Scary,isn't it.


That's pretty much it.

Answer 2

a white hole is supposedly the other end of a blackhole(my fav theory) which reduces overall entropy of the universe (how cool is that, fu¢k thermodynamics) and reconstructs the matter broken by black holes and since they mess with physics, they cannot be sustained.


worm holes in current conditions are nigh impossible.(go watch interstellar for more)

pros. if you could decide where to go with a wormhole, the tremendous distances in the universe would become puny. since the speed limit is 'c' but just the milkyway would take 100000 years to cross at that speed.

cons. you wouldn't know where you're going to.
looking in space is looking back in time. what we see is what used to be and not what is. the scenery we see 10 billion light years from us might very well be the location of a super advanced civilisation right now. but we won't know until 10 billion years.
