Here's an interesting concept:
You are out for a walk on a dimly moonlit night, and you somehow stumble upon a magic door. This is a very powerful door, and you have no way of comprehending how it works.
The only way to see what is on the other side of this door is to open it and walk through the doorway.However, though you would very much like to see what is on the other side, you are hesitant. Why? Well, there's a sign by the door that reads as follows:
"Do not enter. Those who enter this doorway will be forever erased. Everything you have created, all memories of you, and all changes you have made to the universal time line will cease to exist in past, present, and future. You will not die- you will simply vanish entirely from existence."
This is a bold claim- though there is no proof that this is warning holds any truth or value at all.
A man comes up along side of you, and reads the sign just as you have. With a roll of his eyes and a sigh, he says to you, "Watch this", and opens the door.
On the other side, only inky blackness, stretching on to eternity.
The man states that is merely because the light is turned off, and there are no windows.
He motions to step inside...
----------------------------------------------------------------------------------------------------------------------------------------------
Consider this now: You can disprove the warning if the man steps inside, and then, subsequently, steps out, quite easily.
However...Is there any way to prove that the warning holds true?That is what I wish to discuss.
