In a universe where all that has ever existed and will ever exist— already is, (because energy cannot be created nor taken away), do parallel universes exist simply out of possibility? Are parallel universes created by chance of thought or was that thought predestined in order to create an alternate world? With the laws of energy, a thought cannot be something new spawning another world, so did that world already exist influencing the thought? 

This is something to think about while shampooing your hair.
