How time travel works

## How the TTD works.

The TTD allows its user to travel back and forth within the timeline at will. Anyone who uses the device to travel through time is able to change the past, even in cases where a paradox is created, and return to the present altered by the change, just like when Josh meets Joosh. When Josh, Tiger and Wolf travel backwards 11 seconds repeatedly, the only group that makes it to the room is the original group, this is because being the first they had no other group ahead to distract them. The following groups, seeing the groups before them, were condemned to wonder about the possibility of having free will and therefore to become distracted.

## Multiple time branches.

Some versions originating from these time jumps decided to jump to other eras, while the rest tried to run to the room with Stu's brain, all failing and dying. Having countless duplicates of Josh and the gang jump to different times at the same time to alter them caused a paradox and the creation of several alternate timelines as well as a hole in the space-time continuum in the Horsehead Nebula and speeding up the Big Time. When Susan explains the creation of other timelines, he says that this happened for every jump made by the protagonists, even those that occurred before the sequence in "The Brain Job". However, this would go against what we know about time travel, but it is highly possible that it is an exaggerated lie told to entertain viewers of his show and make the characters feel more guilty. The reason why the original version of the 3 protagonists must answer for the crimes of all their other versions, is because they were the first and only ones to reach the room with Stu's brain, instigating their duplicates to escape their fate.

## Nut-Faced Josh and Bin Laden.

As for Nut-Faced Josh, after Stu's deactivation he was able offscreen to procure a TTD from the corridor where there were a potentially infinite number of variants of the group. After taking it he went back in time inside that timeline and became friend with Bin Laden. After Bin Laden got caught and escaped he managed to find Haven, and instructed Nut-Faced Josh on how to get there. After he showed up in Haven with all the famous people he had saved across time, Bin Laden killed him, he took over the TTD and aided the original Josh by using Nut-Face Josh's ear to make a DNA-based, cross-temporal aural transmitter. Since these temporal changes didn't affect the existence of either Josh or Nut-Faced Josh, this events could have happened in the same timeline.

## Why Nut-Faced Josh managed to go back in the same timeline while the other josh ended up in other realities.

Since the other Josh, Tiger and Wolf who managed to escape the corridor simultaneously jumped to other time periods during the span of 11 seconds, the Universe could not contain them within the same reality and therefore created multiple timelines to send them to, identical in what had happened up to the moment of the jump, minus other time travel versions of themselves. However, as for Nut-Faced Josh, he recovered the TTD **after** the automatic defenses were disabled due to the original group destroying Stu's brain. Traveling after those countless other versions had already gone to parallel realities, Nut-Faced Josh was the only Josh left (besides the original) in the timeline, so *he was able to move within it without ending up in a parallel dimension.*
