Element Zero (Earth-3812)

Element Zero, also known as "eezo", is a rare material that, when subjected to electricity, releases dark energy that can be manipulated into a slipspace field, generation a dimensional subdomain that raises and alters the mass of objects within that field. The slipspace fields are used for a multitude of purposes, from enabling faster-than-light travel without causing time dilation, to manufacturing high-strength materials.
