'''Neutronium''' is a material that exists primarily in the cores of [[neutron star]]s. It is a lattice of neutrons (one of the three building blocks of matter at the atomic/nuclear level) that is generated when the tremendous pressure generated by a [[supernova]] (the explosion of a large [[star]]) acts on its core, causing all its electrons and protons to merge and form neutrons (this is the same as the process of beta decay, that generates beta radiation, only in reverse). These neutrons are very densely packed, and bind with each other using subatomic particles called gluons. This makes it the hardest possible substance in the universe. The spins of these neutrons add up to generate extremely powerful magnetic fields, which have been detected by astronomers. The high density of neutronium also generates a strong gravitational field, sometimes so strong that it may cause the neutronium core to collapse in on itself, forming a gravitational [[quantum singularity|singularity]] (colloquially known as a [[black hole]]).

Revision as of 20:21, 3 September 2014

Neutronium is a rare, dense mineral, found naturally in the cores of neutron stars. It was impossible to scan inside neutronium. (TNG: "Evolution"; TOS: "The Doomsday Machine") Despite many readings and theories, the Federation was never able to produce neutronium artificially. (VOY: "Think Tank")

In 2267, the sensors of the USS Enterprise recorded a pure neutronium hull on the extra-galactic planet killer prior to its destruction. (TOS: "The Doomsday Machine")

In 2366, Doctor Paul Stubbs studied the cyclical decay of trace amounts of neutronium in the Kavis Alpha sector through the use of the probe "The Egg." (TNG: "Evolution")

In 2369, the USS Enterprise-D encountered the only known Dyson sphere. The structure was composed of a carbon-neutronium alloy and was impervious to phaser fire. (TNG: "Relics")

The Iconians had mastered the use of neutronium, and used it on a ziggurat containing a gateway on the planet Vandros IV. This was discovered by the Dominion in 2372 and was destroyed by a joint Starfleet-Jem'Hadar team before a group of rogue Jem'Hadar could use the gateway. (DS9: "To the Death")

The Dominion had begun using neutronium by 2375 and used it to protect the entranceways on Dominion Headquarters from weapons fire. (DS9: "What You Leave Behind")

It is assumed, though unclear, that neutronium is a harder substance than rodinium since neutronium seems to be impervious to weapons fire while rodinium can be destroyed by Romulan plasma torpedoes. However, according to Spock, rodinium was the hardest substance known to Federation science as of 2266. (TOS: "Balance of Terror") Neutronium was mentioned in 2267 during the confrontation with the Doomsday Machine. So, it is possible that neutronium was first discovered by the Federation sometime between those two incidents.

Neutronium in the Delta Quadrant

The crew of the USS Voyager learned that the Borg never assimilated the knowledge to collect or create neutronium. (VOY: "Think Tank")

Separated from the Alpha Quadrant in 2371 Voyager encountered neutronium several times while stranded in the Delta Quadrant.

In 2371, Voyager encountered an artificial asteroid composed of a neutronium alloy created by the Vidiian Sodality. (VOY: "Phage")

According to an Alpha Hirogen hunter, at least one collapsed star in the Delta Quadrant had a neutronium mantle. The hunter claimed to the crew of Voyager that he tracked a silicon-based lifeform through this mantle. (VOY: "Prey")

In 2375, Voyager encounter the Think Tank, who traveled aboard a vessel composed of a neutronium alloy. This impressed the crew, who had rarely encountered it before. (VOY: "Think Tank")

Neutronium was also mentioned in a joke in TOS: "A Piece of the Action" equating it to steel.
The term was coined in 1926 for a hypothesized element with the atomic number 0 and currently is used for a degenerate form of matter which cannot exist outside neutron stars. Since 1942, it has been used in various science fiction material to refer to a super-dense alloy or a trans-uranic element on the periodic table.
