Observer Effect

The observer effect was an effect that the weapon ran on, alongside quantum physics, vunktotechnology, the superforce and vundatechnology. (PROSE: The Eyeless)

Behind the scenes

 * Lance Parkin, author of The Eyeless, described the observer effect in the Doctor Who universe as the Time Lords' effect to "observe history" into existence, which allowed them to reshape the universe through their perception. Elements of this are seen in Parkin's contexulization of the Time Lords' Non-interference policy in his novel The Gallifrey Chronicles.
