Hilbert space

Hilbert space, also known as n-dimensional space, was the dimension in which tachyons existed and hydrogen atoms were created.

In 2269, Montgomery Scott modified the USS Enterprise (NCC-1701)'s transporters so that an object would be placed in a tank in which Hilbert space would be formed and the resulting tachyons would be used to create a copy of the object. Spock One, a duplicate of Spock created by the process, later modified a shuttlecraft's engine so that it drew energy directly from Hilbert space, thus enabling it to travel at warp speed.
