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)
I don’t think you understand that getting some hokey answers when you do an asklemmy thread about the supernatural is par for the course.
