Time distortion

Time Distortion was a disturbance in space-time which may have been the result of anachronisms.

Cyber-Technology could detect the Doctor's TARDIS by registering the time distortion it created. (DW: Attack of the Cybermen) It is possible that all time vessels generated distortion, as the Doctor was able to track the Rani based on this factor. (DW: The Mark of the Rani)

Time distortion was present in the Humanian Era; which was the time of Humans, the Sensorian Era and the Sumaran Era; which relates to the Sumaran Empire, the Manussans, and the reign of the Mara. (BFA: Neverland)
