"MechanicsSchrodinger's Dog said:Actually what the hell is dilithium, I always wondered?![]()
Warp cores utilize a matter-antimatter reaction that is regulated by dilithium crystals. When matter and antimatter are exposed, they annihilate each other upon contact. This annihilation releases colossal amounts of energy. Dilithium crystals are used to regulate the reaction because they are nonreactive to anti-matter when bombarded with high levels of radiation. The matter used in the reaction is usually deuterium, an isotope of hydrogen, and the antimatter is usually antideuterium, the corresponding antimatter to deuterium. The matter and anti-matter reaction inside the dilithium matrix is usually referred to as the matter-antimatter reaction assembly (MARA). The MARA is surrounded by a magnetic field to prevent the highly reactive anti-matter from escaping the assembly. The energy is then transferred into a highly energetic form of plasma called warp plasma.
This warp plasma then travels to the warp nacelles via magnetic conduits. The warp coils are exposed to the warp plasma by plasma injectors, which carefully release the plasma into the coils. When exposed to such energetic plasma, the coils create an energy field called a warp bubble. The warp bubble expands space behind the vessel and contracts space in front of the vessel, and the warp bubble forms the barrier between these distortions. The bubble is accelerated while the space inside the bubble does not technically move, so the vessel does not experience time dilation, and time passes inside the bubble at the same rate as time in the other parts of the galaxy.
Warp cores can use other sources of energy besides a MARA, such as an artificial singularity. On starships, warp cores are often the main source of energy for primary systems in addition to propulsion."
