The Importance of Continuous Transitions in Energy Levels

The electron has a range of energies and positions and they can change over time. Just because one never observes an electron at the intermediate position doesn't mean it can never possibly be there after all, that's the empiricist mistake. The transition between n equals two and n equals one, for example, can be continuous, even if those states themselves are discrete. In quantum physics, no discontinuous change is necessary,. Even though all measurable quantities are discrete, it works as follows. Let us start by imagining some parallel universes stacked like a pack of cards with the pack as a whole representing the multiverse. Such a model in which the universes are arranged in a sequence greatly understates the complexity of
