That's me. I'm one of those people who signed up, never posted a single comment, but somehow got banned for life. What am I supposed to do now?
Edit: I should note that I am not allowed to follow anyone because of the ban.
Thank you. So basically the parent comment was talking about experiments for validating quantum non-locality at galactic scales.
And the experiment mentioned in your link confirms this non-locality up to the distances of 600 light years, but we want to confirm it for even larger distances and times, that's why there is a need for techniques like the subject of this discussion.
