  Worm Holes - White Holes - Crystalinks
White Holes are the theoretical exact opposite of fl holes, and their existence is implied by a negative square root solution to the Schwarzchild metric.
In astrophysics, a white hole is a postulated celestial body that spews out matter, in other words an anti-fl hole, or the time reversal of a fl hole.
The existence of white holes is hypothetical, as they appear to violate the second law of thermodynamics.

 White hole - Wikipedia, the free encyclopedia
In astrophysics, a white hole is a postulated celestial body that is the time reversal of a fl hole.
White holes appear as part of the vacuum solution to the Einstein field equations describing a Schwarzschild wormhole.
The existence of white holes that are not part of a wormhole is doubtful, as they appear to violate the second law of thermodynamics.

 White Hole
White holes are similar to fl holes except white holes are ejecting matter verses fl holes are absorbing matter.
A worm hole, which joins white holes, is known as the Einstein-Rosen bridge and is one of the most fascinating concepts in theoretical physics.
The oscillations between the fl holes at opposite ends of the wormhole force the fl holes to become white holes that eject matter and antimatter in opposite directions forming the spiral arms of stars within the galactic disk.

 Curious About Astronomy: What is a white hole?
White holes are not something that it is possible to understand using physical intuition.
White holes pop up in general relativity (which also explains the expansion of the universe) and that theory as a whole is not easy to understand physically.
A white hole is a place where (if it could exist with any matter in it - which it can't) matter would pop out into the universe.

 White holes, black holes
I heard from someplace that quasars are considered by some to be white holes simply because for a quasar to be as bright as it is and for it to be a supermassive fl hole, it would have to consume more matter each year than there could be around it.
White holes were considered to be the 'exit points' of fl holes, or so I've heard.
As fl holes devour energy and matter from space, white holes are supposed to throw high quantities of matter and energy.

 Mysteries - Black Holes
We suspect that most of the fl holes that are actually out there were produced in the deaths of massive stars, and so we expect those fl holes to weigh about as much as a massive star.
White holes are a perfectly valid mathematical solution to the equations of general relativity, but that doesn't mean that they actually exist in nature.
The white hole may be somewhere very far away from the fl hole; indeed, it may even be in a "different Universe" -- that is, a region of spacetime that, aside from the wormhole itself, is completely disconnected from our own region.

 White holes - Unexplained Mysteries Discussion Forums
Black holes are the greatest energy producers in the gallaxy so there is no need for a white hole.
White holes can't exist well not in this universe, because to have the matter come out of the white hole it must have negitive gavity and that would cause the hole to fall apart.
Perhaps all fl holes are the recyclers of matter which returns all things to the singularity aka the "white hole" in which they are released back into existance as new matter.

 White Holes - Astronomy.com Forums
If white holes were to be discovered, I have read that a white hole is the reversal effect of the fl hole.
Also, the white hole if an object tried going through or out of it, then the object would age much faster through the speed of light, while the outside universe would be traveling through the past or slowing down drastically.
Well that s one theory i have heard,the white hole is supposed to be at the opposite end of a wormhole that expels the matter that a fl hole pulls in.,but thats just theory.

 White Holes - SciForums.com
Also, there is strong indications that white holes are the same as the fl holes, or are at least indistinguishable for an observer.
Since a fl hole does just the opposite, then I think that matter is broken down on the quantum level and somehow transported and expelled to and from a white hole.
I think that the holes are connected to another universe and the reason that fl holes suck in things is that it is trying to keep the amount of matter a constant between the universes.

At one point scientists speculated that quasars may be white holes, but now we are fairly certain that quasars are powered by supermassive fl holes, in which case the light we see comes from matter as it falls into the fl hole.
It is mathematically possible, in the case of rotating fl holes, for there to be a fl hole and white hole connected by a wormhole.
If they did exist, anything falling into such a fl hole would indeed be ejected from a white hole (after experiencing some extreme physical conditions) possibly in a distant region of spacetime (possible in the past or future), or even in another universe.

 White Holes - an Astronomy Net Blackholes2 Forum Message
The problem is that without knowing the over all wormhole topology of the hole and the space it is not known whether its even falling out into the same universe from which it fell in.
The region in which it falls in is called the fl hole and the region where it falls out is called a white hole.
The problem with transversing a wormhole and getting out of the hole is that in order for the wormhole to be a stable connection between the spaces there needs to be exotic matter(matter with negative energy) at that location.

 Black Holes   (Site not responding. Last check: )
A fl hole has an infinity at its very center." To many people fl holes are nothing more than over dramatized myths of science fiction writers, however to an astrophysicist they represent the only accepted place in space-time where the laws of physics completely break down.
Since a fl hole represents a complete absence of light (when viewed by humans), there needs to be a method other than sight by which to find a fl hole.
If a fl hole were to spin too fast, these event horizons would become closer and closer, until they touched, at which time the fl hole would explode, leaving nothing but a naked singularity among the cosmos.

is the mass of the fl hole, as the radius (r) of the star decreases, the gravitational field on it's surface increases.
This is said to be of a white hole, which supposedly demonstrates the opposite feature to that of a fl hole.
A fl hole is said to encompass the four dimensions of space and time, thus as a body approaches the event horizon, time is distorted due to the force of the acceleration, and force of the field.

If an astronaut were inside the fl hole, he or she might have a chance to view the singularity before he/she were stretched and killed by the increasing tidal forces.
Hence, the emission of backward-in-time photons by a fl hole is equivalent to the emission of particles of matter by the hole.
If a fl hole is an object that things fall into but not out of, a white hole is an object that things can come out of but not fall into.

 Black holes, white holes, worm holes
White dwarfs are the result of a collapse of a star whose mass is less than 1.4 solar masses (1 solar mass = mass of Sun), and is formed from the remnants of a planetary nebula.
Black holes are the remnants of a neutron star that collapsed upon itself due to its immense gravitational force.
They concluded that the core was a fl hole, because only a structure of this type can concentrate a small amount of matter in such a small space (around several billion solar masses into a sphere of a light year in diameter).

 Black Holes   (Site not responding. Last check: )
In a Kerr fl hole (a fl hole that assumes the star's core was spinning and had a magnetic field when it collapsed), the singularity is theorized to be ring-shaped.
The immense warping of space around the hole would cause a spaghettification effect - you would be pulled apart because your feet (assuming they went feet first) would be far greater than the force on your head, and they you would be pulled as one pulls dough into a rope.
The idea of a white hole is the opposite of a fl hole, and is entertained more in science fiction than in actual science journals.

If the white dwarf is alone like this, however, we have very little chance of seeing it from across the Universe.
Now, white dwarfs may typically be about half the weight of our Sun, or up to 1.4 times as heavy.
Now, this may not seem like much, but consider this: If you were born with a twin, and that twin went to live on a white dwarf, by the time you were 75 years old your twin would be nearly a month younger.

Black holes and neutron stars are the only objects known to physics that are sufficiently compact and massive to fulfill astronomical observations of those very strong emitters of radiation
Black holes and white holes may have an importance greater than all stars, galaxies and clusters because that may offer a model of the life, death, and rebirth of the universe itself.

 Black Holes Made Simple
If a white hole and a fl hole could be linked somehow, then stuff which falls into the fl hole could suddenly appear coming out of a white hole elsewhere in the universe.
The first problem is that the fl hole and white hole would have to be very similar, and so even a small particle could break the symmetry and destroy the worm hole.
The gravity around fl and white holes is so large and varies so much in space that anything in the region of a fl hole would be ripped apart.

 Stickpage Forums - White holes
For a fl hole, all geodesics at the event horizon may enter but not leave, however, if you reversed the direction of time, the same fl hole with 'positive time' becomes a white hole with 'negative time'.
As you enter a fl hole, the object that formed it is still in front of you, filling the space-time with gravitational radiation, which makes the entire edifice of stacked, connected universes dynamically unstable.
Not unless it entered the fl hole end in the first place, or spontaneously was produced inside the Kerr worm hole by perhaps a quantum mechanical process of some kind.

In conjunction to hearing about fl holes, most people have heard the phrase 'white hole.' It is a confusing phrase and is generally avoided by serious scientists, I've been told.
Black holes are rather like subway terminals in that sense; if you walk down the stairs to take a train, you've got to walk back up the stairs when you exit.
I coast away from the fl hole's gravity well at the same speed I entered, the mirror-image of my worldline when I entered the 'well---which kinda means I end up perched at the lip of the 'well, again, with the option to fall back in or to leave and explore.

When stars that are more than four times the mass of our sun reach the end of their life and have burned up all of their fuel, they collapse under the pressure of their own weight.
Since the fl hole would not have a singularity, Kerr believed it would be safe to enter it without being crushed by the infinite gravitational force at its center.
If Kerr holes do exist, it might be possible to pass through them and exit out of a "white" hole.

 BLACK HOLES by Ted Bunn
Loosely speaking, a fl hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull.
Near a fl hole, this distortion of space is extremely severe and causes fl holes to have some very strange properties.
If you were falling into a smaller fl hole, say one that weighed as much as the Sun, tidal forces would start to make you quite uncomfortable when you were about 6000 kilometers away from the center, and you would have been torn apart by them long before you crossed the horizon.

Some calculations show that a white hole that is not rotating could get turned inside out by gravity, having a fl hole form around it.
But if the white hole is rotating, it can't suffer this fate, and will not be hidden from the rest of the universe.
