Black hole (astronomical object)


 * Uldir Lochett: "If it's any consolation, nobody knows exactly what you feel when you cross the singularity of a black hole. It might be extremely painful when every atom in your body collapses into neutrons. And since time virtually stops, it could last a really long time."
 * Leaft: "You're trying to cheer me up."

Black holes were a astrophysical phenomena with sufficient gravity to prevent even light from escaping its grip. They were created from the wreckage of dead hypergiant stars and protoquasars.

Carachteristics
Some hypergiant stars where impossibly massive and any other object their size would immediately collapse into neatron material, but in a star, the titanic nuclear reactions in the stellar core kept the star as normal matter. Black holes occured when a hypergiant star died and the nuclear rections which supported its weight ceased. The star collapsed under its own weight, with such force that not even neutron material could support it. In a monstrous flash of raw power, the atoms and even the subatomic particles would obliterate, simultanousely greatins a hypernova, a giant explosion worth 100 supernovea. No matter remained, but although there would be no matter present, the gravity still remained. The Gravity of a black hole was so strong that it skewed space-time, as well as Hyperspace, causing time to stop and the laws of physics which governed a whole universe to become meaningless. The gravity was also strong enough to cause light to fall into the hole, making the hole itself completely black, hence the name. The region where the blackness began was known as the event horizon, beyond which nothing, even light could escape. Matter which entered a black hole would be transformed and locked away for ever. However, there was a way for matter to exit a black hole, namely through a white hole, which worked in the opposite way to a black hole. Matter could travel through hyperspace wormholes if they occured. When black holes met white holes, they became interlocked in battle, with the black hole trying to consume the white, and the white hole attempting repel the black. Should the black hole be of greater mass, it would consume the white hole, becoming significantly larger in the process. Should the white hole be larger, it would first repulse the matter trapped within the black hole before repulsing the black hole itself. However, should both holes be the same size, they would be locked together in a ceasless battle.The black hole would suck in matter and the white hole would repulse it back out. These meetings between white and black holes were known as "dances of death".

There were rumours of clashes between supermassive black and white holes.

History
Black holes were common in the galaxy, particularly in a cluster known as The Maw. One existed in the center of the galaxy, known as a supermassive black hole, and one was also located along the Hydian way, near Dathomir. Their intense gravity, combined with the difficulty in detecting them (as they absorbed all light) and the fact that smaller black holes could "wander" through space, made them dangerous navigational hazards which snarled hyperspace routes. Hundreds of vessels were believed to be lost every standard year to wondering black holes, and the effects of an object in hyperspace or realspace colliding with a black hole were the stuff of every spacefarer's nightmare. Unidentified black holes were marked as Gamma-class navigation hazards. Despite the danger involved, Black holes were used throughout much of the galaxy's history as sources of energy. Subatomic knots of space-time were created in encompassing unmanned energy refineries, and were an intricate part in the function of all manner of gravitational devices and generators.

Notable black holes included:

 * Galactic Centre (SMBH)
 * Black Hole of Nakat
 * Black Hole of Quintas
 * Endor Gate
 * Black Holes of the Maw cluster
 * Black Holes of the Tyus cluster.

Supermassive black holes (SMBH)
As the name already suggests, supermssive black holes are black holes of incredible size and, more importantly, mass and gravity. It wasn't the volume of an SMBH that made the difference, although most were significantly more visually imposing, but rather the actual mass and gravity. Supermassive black holes usually formed from protoquasars, the largest star-like occurances in the universe, and gained enough mass to keep the billions of stars in an entire galaxy in their orbit. Another known way for supermassive black holes to form was through the merging of many other, smaller black holes. It is rumoured that supermassive black holes clashed with supermassive white holes. One supermassive black hole made up the galactic centre.

Artificial black holes
In c. 1 ABY, Imperial Doctor Arakkus once simulated the effect of a black hole. He utilized a negatron impact on a dwarf star, causing it to collapse on itself. The resulting black hole slowly sucked in its surroundings. Also, the Dovin Basals of the Yuuhzan Vong could generate small black holes, which they used as shields. By creating the black hole between a ship and enemy weapons fire, the hole could absorb the incoming fire, which was later dispersed harmlessly as low intensity gamma radiation when the black hole would evaporate.
