Interphase

• Spatial phenomenon relating to matter integrity, solidity, presence in continuum (ENT: "In a Mirror, Darkly"; TOS: "The Tholian Web"; TNG: "The Next Phase", "The Pegasus"; VOY: "Distant Origin"; SCE Short Story: "Interphase")
  • Also known as "interspace" (TLE Novel: The Sundered)
• Involves alteration of phase of matter causing it to become undetectable to unaffected matter in continuum (TNG: "The Next Phase"; VOY: "Distant Origin")
  • By terminology, potentially involves modification of quantum signature of matter, causing it to shift partially or fully outside the continuum
• Partial interphase only results in matter being partially placed out of phase with the continuum, rendering effected matter undetectable by and immaterial to the universe at large (TNG: "The Next Phase", "The Pegasus")
  • Permanent, but reversible, alteration of matter via exposure to certain strong frequencies of chroniton radiation (TNG: "The Next Phase")
    • Chroniton radiation signatures left behind by such matter the only known measurable effects of matter in this continuum effected in such a way (TNG: "The Next Phase")
    • Previously pursued by Federation, Klingon Empire, and Romulan Star Empire mid-to-late 24th century as more effective alternative to traditional cloaking devices (TNG: "The Next Phase", "The Pegasus")
    • Effect can be reversed by, among other things, anyon radiation purging the chroniton radiation maintaining the interphase effect (TNG: "The Next Phase")
  • Fields creating such partial interphase effects known, as with many subspace phenomena, to to disrupted by exposure to chroniton radiation (TNG: "The Next Phase")
• Full interphase results in matter being fully placed out of phase with the continuum, pushing it into a deep subspace domain or branch universe (ENT: "In a Mirror, Darkly"; TLE Novel: The Sundered)
  • Known to be caused by interphasic rifts (ENT: "In a Mirror, Darkly"; TOS: "The Tholian Web"; SCE Short Story: "Interphase")
    • Interphasic rifts that connect to deep subspace domains can allow for transport over massive distances at the equivalent of hyperwarp velocities (TLE Novel: The Sundered; TTN Novel: The Red King)
      • Such rifts known specifically as "interspatial fissures" (TLE Novel: The Sundered; TTN Novel: The Red King)
    • Rifts form as a result of gravimetric subspace damage to areas already known to be turbulent in subspace
      • Known examples:
        • Detonation of tricobalt explosives in the gravity well of a neutron star (ENT: "In a Mirror, Darkly")
        • Eruption of a thalaron generator (TTN Novel: Taking Wing)
    • Vessels passing through these rifts undergo full interphase (ENT: "In a Mirror, Darkly"; TOS: "The Tholian Web"; SCE Short Story: "Interphase")
    • Proximity to interphasic rifts known to cause interphase psychosis, whereby distortions in the central nervous system lead to violent, potentially homicidal psychosis (TOS: "The Tholian Web"; TLE Novel: The Sundered; SCE Short Story: "Interphase")
      • Non-humanoid brain structures seem less- or unaffected by interphase psychosis (SCE Short Story: "Interphase Book 2")
      • Interphase psychosis treatable, but not curable, by theragen-derivative agent (TOS: "The Tholian Web"; SCE Short Story: "Interphase")
      • Restoration to original continuum reverts effects of interphase psychosis in a victim (TOS: "The Tholian Web"; SCE Short Story: "Interphase")
    • Interphasic rifts disruptive to stellar fusion (TLE Novel: The Sundered)
• Interphasic phenomena can even reach outside the multiverse entirely, connecting to de Sitter space and reaching entirely disjoint universes (TOS: "The Tholian Web"; DS9: "Playing God"; TTN Novel: The Red King)
  • Inclusion of "Tholian Web" in this category is presumptive, but the utterly empty void portrayed seems more likely to be a disjoint universe than a branch of the primary universe
