What is the Possibility of White Holes?

[Dr.Brain]

beYond that?

1) I read about BIG BANG THEORY .. I was wondering if their was a lump of matter that blasted and as a result the universe took its shape...perhaps, from where did that lump of matter came...and when it came into being " by what type of space was it surrounded by?"

2) Can white holes exist , whose possibility has been proved using relativity because in relativity the equations are time-transferable.The general relativity says that a BLACK HOLE reversed in time is a WHITE HOLE which instead of sucking in the matter , keeps splitting the matter out of it.

well as for your first question The universe formed out of nothing matter space time and energy all were created with the big bang so there was no space pre big bang. and the sum total of all matter and energy in the universe is exactly 0 to every negative there's a positive which balances it to 0.

as for your second question I am unsure.

while black holes are hard to see
a white hole would be hard to hide
and we have never seen one
there for they most likely don't exist

So far as the big bang goes, inititially there was just energy. Matter did not come into being until a short time later. Where the initial energy 'came from'? That is unknown and very possibly unknowable. Quantum theory permits energy/particles to literally appear from virtually nothing for a brief amount of time. Many think this kind of quantum weirdness is at the heart of the mystery. Hawking and others have suggested the net energy of the universe always has, and always will be exactly zero. The basic contention is that gravity is a form of negative energy and it exactly offsets the positive energy contribution of matter and EM in the universe. It is an appealing idea that makes sense. While the sum of its parts is zero, the parts themselves are not - which is not such a bad deal.

White holes? Who knows. It is a theoretical novelty for which no real observational evidence exists. Mathematical physics is like that. Not every every solution has a real world counterpart.

The energy is probably just an effect of spacetime distortions. These spacetime distortions (due to the Uncertainty Principle) can create amounts of energy which allow the creation of virtual particles. The Uncertainty Principle is probably an intrinsic part of our Universe and probably plays an important role in the explanation of the Big Bang.

(1) Big Bang Theory does not describe the ultimate source/cause of the universe. It explains what happened immediately after the universe began.

(2) White holes are a mathematical possibility, but there is (so far) no physical evidence to show that they actually exist. On the other hand, there is good evidence to support the existence of black holes.
