Is there something unexpected going on here?
Why do time-travel stories often have the characters "returning" to the future?
The linked question was closed three years ago and yet it has jumped onto the front page today?
Superficially I can see the reason it shows up is an edit in one of the answers, but I was surprised to see the promotion effect didn't care that the question was closed.
The only questions filtered from the home page are either historically locked, heavily downvoted (less than -3 on main or -7 on metas), or deleted. All other questions will show up on the home page when bumped.
In the case of closed questions, this is a great way to ensure that wrongful closures are reversed. It also allows other users to double check on any edits, in case further edits or a rollback is needed.
