1. In a hydrogen atom, how do you compute the total numbers of positions possible (possible Psi^2) for the electron? Does each position signify one world? 2. Or do worlds only came about if there are quantum choices to be made? For example, as each hydrogen and oxygen dissolve and reform the hydrogen bonds. Do this create worlds? 3. If so, how many worlds possible or can exist in a cup of water? Does each world as big as the universe or solar system or only as big as the cup of water? 4. How does this "relative state" relate to it? How about the idea of the universal wavefunction, where all possible states already exist in the cup of water. If so, is this synonym to worlds splitting? How many kinds of MW are there? Please differentiate it by means of the example of the cup of water (assuming it is 250 ml). Thank you.
