Any ship to enter a center halo would immediately become trapped as the halo "hardens" around them, preventing the ship from leaving. The ship also becomes isolated from the normal space-time continuum, thus turning the passengers essentially immortal.
Time moves much faster inside a center halo as approximately 1 day in the halo equals 55 years outside.
The halo appears as a thick, bright yellow nebula.
- The center halo originates from the Farscape season 2 episode "the Locket" in which two of the main protagonists are trapped inside the halo for 55 years.
- Tim is mentally affected by the presence of center haloes due to his mind being connected to the space-time fabric.
