In Dark, the biggest mystery of the first season was who kidnapped/killed the children and why. Including, why they had burns across their eyes.

After watching the entire series, I think I understand who did this, but I still don't understand why. Was it

Noah and Helge who killed the kids? The first season set up this plot line as if it was someone experimenting with time travel. But it doesn't really make sense for Noah and Helge to be experimenting with time travel if Noah (from the past and his younger self) already knew he could time travel by going through the cave, and if he knew that Tannhaus and the time machines existed.

Mechanistically (from the internal logic of the show), I don't understand how this was possible either. Didn't they need

the dark matter in order to time travel? At least, that's what Jonas, Martha, Claudia, and everyone else required (as we saw numerous times). So how was the time travel even working?

And again, why were these peoples faces being burned off? And what was the motivation for doing it?

This is a variation on Kevin's answer with the focus on a different part.

To summarize:
Noah had no access to a time travel device and therefore developed his own. The tunnels were available (for some time) but they didn't allow him to travel to where he wanted to go (1920). He used the children as guinea pigs to see if the chair worked, and there were many experiments needed.

There are three ways to time travel: using a device (suitcase or golden ball), using the portal (blue orb), or using the tunnels in the cave.

  • By device (suitcase, chair or golden ball), which travels with the traveller
  • The portals (blue orb), which stays behind, the traveller cannot use the same portal to return
  • The tunnels in the cave can be used by anyone, but they only connect 1953/4, 1986/7 and 2019/20.

In 1920, Adam has a portal device, which Noah uses (in 1921) to get to 2020. From that point on, he stays in that time, working together with Claudia and Jonas.

In 2053, Noah's child is taken and he vows to Elizabth to find her again. He uses the portal in the power plant (the same one Jonas travels through) to get back to the 1953/1986/2019 time period, which is connected via the tunnels.

It's unclear which time period Noah he visits first (unless I missed it), but he is seen pingponging between them. Remember that at some point the Stranger (middle age Jonas) closes these tunnels as well, so Noah is stuck in time without any available portal or time travelling device.

It's important to realize that Noah has no access to time travel other than the tunnels, which means that Noah is unable to get back to Adam's time.

This is why he develops the chair, as it is his only way to get back to Adam. Noah is devoutly loyal to Adam, who seemingly holds all the answers. Therefore, Noah wants to get back to Adam in his quest to find his daughter.
Unrelated to the question, Adam uses Noah's passion to find his daughter to steer him towards killing old Claudia, claiming that the last pages of the book hold the answers Noah is looking for (where his daughter is), but Adam's real goal was to kill Claudia.

The children that are abducted and essentially killed via the chair were experiments to check if the chair was working.

And again, why were these peoples faces being burned off? And what was the motivation for doing it?

It seems like the chair with the metal ring around your head worked but killed the traveller in the process, as it killed everyone who used it (the abducted children) and burned their eyes off, but it did send their bodies to another time period.

But when Noah sends young Helge back to his time in 1953, we see that Noah has developed a new and non-lethal kind of chair, one that is encased in a much larger metal cylinder. Based on the repeated failure of the earlier model, he presumably rebuilt the chair and managed to make that one work.

    This isn’t a variation on Kevin’s answer, it’s an entirely different one. Kevin’s answer was that it was all in service of sending the child Helge back to 1953, which didn’t make sense to me. I don’t think your answer is quite right either though. His motivation isn’t to get back to Adam. He’s loyal to Adam, but his immediate goal is to do what Adam told him, do his “final cycle” in order to get the missing pages and thereby find his daughter. I’m not sure whether he was using the time machine to find the missing pages or to get to Claudia, but either way the pages is what was motivating him. Commented Jul 12, 2020 at 14:33
  • @KeshavSrinivasan: So how did middle age Noah find his way back to Adam, to receive the instruction to get the pages? He was never in possession of any time travelling device except his chair. Sending Helge back to 1953 is a bootstrap as it ensures that adult Helge will help Noah to create the chair (by finding children to test with). That's not the purpose of the chair, it's done to ensure the chair is created.

    @KeshavSrinivasan: Just to be clear, I consider it a variation because sending Helge back was essential to the chair's (admittedly bootstrapped) existence (because Helge needs to grow up and help Noah), but I disagree that it's the ultimate goal of the chair (as alleged by Kevin). If the chair only exists to send Helge back to help create the chair, then the chair ultimately serves no purpose, and Noah is reallly not the kind of character who does things for no purpose.

  • Well, darknetflix.io suggests (under “What” and then “chair”) Helge is just another test subject for the chair, just the first successful one. In any case, I don’t think Noah is in possession of the chair in 2041. I don’t know if it was destroyed in the apocalypse or what, but in the years leading up to 2041 Noah is struggling along with the other characters to find a way to time travel, including digging and the experiments with the God Particle which Claudia keeps sabotaging. I think Noah acquires a means of time travel when the adult Jonas does, probably the stabilized God particle. Commented Jul 12, 2020 at 15:32
  • @KeshavSrinivasan: Your argument about how Noah travels from post-apocalypse Winden is already mentuined in this answer.

They weren't being tortured, per se, but used as test subjects on an unready technology. The time tunnel was created "naturally" via the "incident" in June 86 at the NPP. It only went to 53, 86, and 2019. The stranger closed the tunnel in Nov 2019, at the same time young Helge was brought to 1986. At that point there was no "time machine" available so middle Helge and Noah spent 86 "inventing" the chair and refining it so that child Helge could get sent back to 1953 to grow up and help invent the chair in 1986. Since the Chair 2.0 (the one that actually sent Helge back) was used after the time tunnel was closed, it had to have a different power source than the time tunnel. Presumably at that point it was using C137 from the barrels. Middle Helge would probably have ample opportunity to retrieve some of that.

The kids were used as test subjects and my speculation is it went like this:

  • Mads - testing time travel in the "easy" direction, 1986 to 2019. Results: Fatal
  • Eric - testing time travel in the "hard" direction, 1986 to 1953. Results: Fatal
  • Yasin - testing time travel in the "hard" direction at appropriate age. Results: Fatal

I'm guessing that they made "tweeks" after each time that presumably get them closer to the goal of successfully sending Helge back. The other time machines hadn't been invented "yet" from Noah's perspective.

Edit for clarity: Why was Helge important? For three reasons.

  1. Middle-age Helge helps run the chair experiments.
  2. Helge fathers Peter sometime (way) before 1986. Peter is the father of Noah's wife.
  3. Helge brings Claudia into the time travel scene with the book he gives her.
  • First of all, if the experiments were solely for the purpose of sending Helge back to 1953, what is the importance of Helge in the first place? Why is Noah wasting his time with Helge at all? It can’t just be “to help invent the chair”, because according to you the chair’s importance is just because Helge is important. Commented Jul 11, 2020 at 12:20
  • And Noah may not have had access to the tunnels, but couldn’t he have used the handheld time machine invented by H.G. Tannhaus? Commented Jul 11, 2020 at 12:23
  • @KeshavSrinivasan: He simply didn't have it in his possession, and wasn't able to reliably find anyone using it.

  • @Kevin If you go to darknetflix.io and click What and then the chair, it makes clear that Helge was just another test subject, he wasn’t the purpose for which the chair was built. Commented Jul 12, 2020 at 14:47
