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 want it. I have invested all of myself to the existence that I am. Why would I need to bother with it if there is afterlife.
Life is only as meaningful as it is fleeting. As soon afterlife comes into the equation it nulifies all of that. Then you must invent God as an arbiter that gives meaning to your life.
