So, if I claim to communicate with an invisible God, why don't they lock me up? Is it because that's a common form of craziness? Is something only lock-up worthy if they believe in something that no one else believes in? Or does my belief have to physically threaten myself or those around me before they call me crazy?

I've been getting into laymans physics a little bit lately and learning about string theory. String theory is a theory intended to unify quantum theory with the natural forces of gravity, etc. into one consistent theory that explains just about EVERYTHING in terms of physics, the universe and the natural world. However, our limited knowledge makes a theory like this incredibly hard to prove scientifically. So, while we're waiting, I propose a Silly String theory. Because how cool would science class be that day!
