Time travel is the process of travelling to a point in the past or future.
"We think we're free, but we're not. We follow the same old path. Again and again." ― Adult Jonas Kahnwald to teenage Jonas Kahnwald[source]The past, present and future are all connected and affect each other. Whether it is possible to change the future through changing the past is unclear.
Seemingly, changes to the past made through time travel are already accounted for in the future and thus, it is impossible to change the future. This means that whatever happens has already happened. Examples:
- Ulrich travelled from 2019 to 1953 and tried to kill young Helge to prevent the future abduction of children, but only caused the injuries to his face which Helge "already" had in the future.
- Helge travelled from 2019 to 1986 to warn himself
On the other hand, some characters, like Noah, Claudia and Jonas, go to great lengths to ensure that every step will be repeated exactly as it was before, implying that things would change without their intervention and thus, changes to the past affect the future. However, they might have other motives than keeping the timeline consistent. Examples:
- Claudia instructed Tronte and Peter to place Mads' body in the forest where it would be found by the police.
- Future Jonas prevented his younger self from bringing Mikkel (his future father) back from 1986 to 2019, as he believed that doing so would erase his own existence.
- Future Jonas did not release his younger self from the bunker when he was kidnapped by Noah and Helge,
The Chair was a prototype time machine, built in the Bunker behind the Doppler Shack by Noah in 1986. It was located directly above the passage in the Winden Caves and amplified the energy from the passage when it was opened.
