Time loop

A time loop, known technically as a chronic hysteresis (TV: Meglos), was a loop in time in which the occupants experienced the same events in endless repetition.

Science Edit

An accurate time loop took little energy to perpetuate. An incomplete time loop (where each repetition was not the same as the last or the loops were not the same length) was unstable. Energy requirements increased with each iteration. (PROSE: The Pirate Loop)

While there was no known technological method of escaping a time loop, the Fourth Doctor and Romana broke a time loop by deliberately recreating the events of the loop out of phase with the loop itself. (TV: Meglos) The Third Doctor was able to escape the time loop he created around Axos by boosting the signal. This might indicate that the person creating a time loop could still leave it. (TV: The Claws of Axos) As he later related, however, due to the Time Lords tampering with his TARDIS and knowledge of time travel the loop he created was not an accurate time field/threshold (AUDIO: The Feast of Axos) so this may have allowed his exit.

Characteristics Edit

The Third Doctor attempted to explain the concept to the Brigadier and Jo Grant as a "loop in time," the same events in space occurring over the same place in time. Time loops had the appearance of the infinity symbol, (TV: The Claws of Axos) a figure of eight looping through four dimensions.

The threshold of a time loop, possibly called the "time barrier," could be crossed into. Echoes of the past and future could be experienced, such as messages repeating themselves. This was evidence that various futures were possible; a message from the future did not guarantee those events would happen as time was in flux. A time loop would eventually decay naturally over six billion years. (AUDIO: The Feast of Axos)

Chaotic time loops could have the appearance of a spiral or spider web. (AUDIO: Spider's Shadow)
