We are told by nineteenth century physicists and most theologians that energy cannot be created or destroyed, but only changed in form. I suspect the physicists of the day were combating perpetual motion machines, and so designed their universe to behave that way, hence the creation of this thing called potential energy in order to make the equations work. This now seems unlikely, and that while maybe somehow deep down energy cannot be created, the amount of energy stored in space/time seems a lot more than we thought, and so long as we keep certain parameters at zero the potential energy in it is seemingly limitless.
Energy is information, as was posted above, and this leads to a weird aspect of it. Even though energy cannot be "destroyed," every time we use energy in any way we reduce its usefulness -- and if that is not "destruction," what is it? This is the increase in entropy, or decrease in order or information content, that comes with energy use.
In short, my take-away is that we fool ourselves into thinking we have the slightest notion what energy is. We measure it and describe its effects, and it is in essence what we are, but we do not understand.
Ok Frank, so what would be your question for the voice in your head claiming to be God? Right now, only you can hear the voice, no one else, and that's all there is so far--a deep, neutral voice with no discernible source or direction. There is no accompanying sense of "being in the presence of the Lord", etc. It's just a voice, saying "Hello [Frank], I am God. How can I prove this to you?"
"Aha!" You say, "If you were God, then you would already know!"
God laughs. "Of course I know my child! The point of the question is to see if you know..."
So no easy outs. Or at least not that one.
I think I would ask the voice to explain. Everything. Then I'd like to be able to relive the most important moments of my life. The truly important ones though, including all the seemingly mundane choices that might have changed my entire direction. I once read about a west african root bark that caused that reaction in a user and it's fascinated me ever since.
Let me come clean though--my intent with this thread was twofold. First, I wanted to see how many people would ask for an old-school miracle like something out of the old testament, and then point out that most (if not all) of the things we think of as miracles are just magic tricks. Seemingly impossible tasks performed in ways we just don't yet know about. Miracles are born out of ignorance (yes, IMO sheri).
Second, I was very curious to see what kind of answers I would get besides magic tricks. I knew that I had read a really good answer to the question somewhere before but for the life of me I can't remember it. So I think I was hoping someone could remind me of what I had forgotten. Unfortunately of course, I forgot about thread and wasn't on hand to keep things on track (I love that smiley)
Anyway, this might be the last decent day of the year so I'm off for a bike ride. Tiggs, I did appreciate your idea of asking for solutions to near impossible questions. That should obviously be a starting criteria--unknown knowledge that can be proven true. It's just the final step that really knots the problem. Would the voice have to logically explain a paradox? Do the impossible? What actually proves Godhood?
