The Source Loop, is a hypothesis for the explanation of every information source, every 'proved' event or fact. The Source Loop is this formulae: If you were to read a piece of non-fiction text, you would have to back it up with a so-called reliable source, but then you would have to back up THAT source and so on, etc. The result being a infinite loop that makes every proved and tried fact or happening unreliable or credible. Because in its own way it makes everything tried and proved, empty. That formulae makes you think, what is science then? Is it a philosophical intuition that humans have created to explain things, that just can't be explained? Well then, if science explains everything, what is everything? And how is it created?
