Reminds me of the Black Mirror episode called Arkangel [1]. Based on the name it seems that the researchers know that series.

Black Mirror tends to reuse a lot of tech themes across many episodes. The same theme is in the White Christmas[0] episode.

The idea of the "mutability of the past" has been around since at least "1984".

I was thinking it resembled the Weeping Angels from Doctor Who. [1] Once they touch people they disappear forever, seemingly apropos.

Nit: They are not making people disappear but they send them back in time. But I also had to immediately think of them when I saw the title.
