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.
―Uldir Lochett to Leaft after learning their ship is approaching a black hole[src]

Black holes were an 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 .

Characteristics Edit

Black holes occurred when a hypergiant star died and the nuclear reactions which supported its weight ceased. The star collapsed under its own weight, with such force that not even neutron material could support it. The material would collapse into a singularity, creating a black hole with an event horizon. The black hole would begin to destroy the star from the inside, creating a hypernova, and often a gamma ray burst. 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 break down.

The gravity was 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, not 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 occurred. 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 ceaseless 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."

Classification Edit

Black holes came in several sizes. Most black holes began as stellar mass black holes, but could become larger through consumption of matter and mergers with other black holes.

Natural Black Holes Edit

Stellar Black Holes (SBH) Edit

These objects were created in the deaths of high mass stars. Their masses ranged from less than 1 to around 100 ssm. These were the most common type of black hole in the universe.

Intermediate Mass Black Hole (IMBH) Edit

These black holes had masses in excess of 100 ssm and below 1 million ssm. A more common definition of this kind of black hole was a black hole with a mass in excess of what was possible for a star. Intermediate mass black holes formed from stellar mass black holes that had consumed large amounts of matter or merged with other black holes.

Supermassive Black Hole (SMBH) Edit

These black holes had masses in excess of 1 million ssm and below 10 billion ssm. These objects were often found in the nuclei of spiral and elliptical galaxies, and often functioned as a form of anchor around which the galaxies rotated. Supermassive black holes formed from stellar- and intermediate mass black holes that consumed large amounts of matter and/or merged with other black holes. The galactic center was a supermassive black hole.

Hypermassive Black Hole (HMBH) Edit

These were the largest black holes in the universe, with masses in excess of 10 billion ssm. Hypermassive black holes occasionally existed in the nuclei of the largest galaxies, having formed from supermassive black holes that consumed large amounts of matter.

Artificial Black Holes Edit

Low Mass Black Hole (LMBH) Edit

These were artificial black holes with masses lower than 0.1 ssm (33,000 spm). These could be created artificially through the growth of micro black holes or through the evaporation (either natural or artificial) of larger black holes. These black holes could not form through gravitational collapse, as stars with low enough mass to collapse into such objects would form white dwarfs or neutron stars instead. Black holes with masses lower than 0.00002988 ssm (1 spm) were termed micro black holes.

Micro Black Hole (MBH) Edit

These were black holes with masses below 1 spm. Micro black holes were less than a centimeter across. These black holes could be created artificially using incredibly advanced technology. They were incredibly difficult to track if not destroyed after their creation, since they were almost undetectable due to their lack of reflectivity and incredibly small size, yet had sufficient gravitational power to destroy an entire planet.

Nano Black Hole (NBH) Edit

These were artificial black holes smaller than micro black holes, generally below a quintillion tonnes (<0.0001 spm). They were created using the same technology as micro black holes, albeit on a smaller scale. They lacked measurable gravity from long distances, but were to massive to be luminous.

Luminous Black Hole (LBH) Edit

These were artificial black holes smaller than nano black holes, generally below 10 trillion tonnes. They were characterized by the fact that their decay radiation was intense enough to be visible, and thus they were luminous. The largest ones had power outputs of a few watts, but smaller ones were incredibly bright. These objects could be used as ways to store energy for the civilization that created them.

Explosive Black Hole (EBH) Edit

These were black holes with masses of less than 10,000 tonnes. These were extremely luminous, and had short lifespans, often less than 24 hours. These devices were used by advanced civilizations (such as the Celestials) explosives (occasionally as weapons) by placing them near the surface of an object and waiting for them to evaporate. As they lost mass, their energy output became greater and greater, finally resulting in a cataclysmic explosion as they evaporated away the last few hundred tonnes of matter in a cataclysmic explosion. Using such black holes was often easier and more practical than using equivalent amounts of antimatter.

Particulate Black Hole (PBH) Edit

These were the smallest black holes, they could be made in particle accelerators. The very largest had masses of up to a gram. They were used for scientific experimentation.


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.

Supermassive black holes (SMBH)Edit

Supermssive black holes were black holes of incredible size, 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 sometimes formed from protoquasars, the largest star-like occurrences 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 was rumored that supermassive black holes clashed with supermassive white holes. One supermassive black hole made up the galactic center.

Artificial black holesEdit

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 Yuuzhan 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.
