The moon is over my right shoulder behind me as I watch the waves at the lighthouse waiting for the sunrise. The waves coming in are powered in most part by the changing gravitational pull of the moon as it revolves around the earth. We can use Newton’s classical laws of motion to predict where the moon will rise and set at any point on the earth. We can’t predict the height of the ocean, except as an average height based on the tide. We can’t predict when a wave will hit the shore tomorrow.
With waves in the ocean, we can see the water and watch the wave travel through the medium of the water. As we listen to the waves crash and hit the shore, it is obvious that the waves have energy. The energy of the universe is contained in probability wave – the probability of an event happening at any point and time can be predicted, or at least estimated. It is the interaction of these probability waves that shape the universe.
