A Time Loop is a distortion in the Fourth Dimension where time folds back on itself. A TARDIS can be programmed to time loop an area at least 100 meters long. This is very difficult to do and results in a TARDIS (and the operator) being trapped in the Time Loop. It is possible for a TARDIS to escape from the Loop, but this is even more difficult to achieve. Stopping the Time Rotor while in the Vortex might allow a TARDIS to escape from some types of Time Loops (but not Chronic Hysteresis). It is possible for a vessel trapped in a Time Loop to be forced free by another TARDIS in the Vortex.
It is also possible to set up a temporal bubble around a particular room within the TARDIS, effectively trapping everything within the room inside an endless time loop. Under certain dangerous situations the TARDIS will automatically put the inside of the control room into a time loop to protect the crew within such a temporal bubble.
