Obviously a hypothetical scenario. There is no way to pass on the knowledge to anyone else. Time freezes for you only, and once you have your answer you are out of this world.
The question can allow you to see into the past, present and future and gain comprehension of any topic/issue. But it’s only one question.
What would you want to know? Personally I’d want to see a timelapse or milestone glimpses of humanity’s future until the end of Earth’s existence (if we survive that long)
What was the single thing I did that had the last direct impact on myself, that had the greatest lasting impact on anyone else?
Things like spending the extra time one day making a cup of coffee made it so this specific person was stuck behind my slow-ass speed limit driving, averting what would’ve been a multi-car pileup or some shit like that.
Why cut yourself short with single? I’d surely want to know if there were more things like that in my life
I mean, ideally I’d want a ranking of every decision I ever made in my whole life on that scale, so I could thumb through it.
My favorite concept for an afterlife is being handed a magic book that contains the answers to every question like this where it’d be impossible to track the data, and it would be able to display it in any way you want.
