Help me understand something. I think of an object as a combination of bezillions of wave functions related to its particle composition, and as any movement occurs involving the object, those bezillions of wave functions are multiplied many times over each instant. Is that a faulty picture?

Now I think of the wave function as a set of possible, I guess we say the set of probable combinations of location/momentum of the particles.

So how many worlds are we talking about just to represent all of the possible combinations. For each instant, whatever an instant is, we have the bezillions of wave functions times all the possible location/momentum combinations of all the particles.

In MWI does each of the bezillions to the bezillionth power of possibilities of location/momentum combinations have a separate time line.

If so, then the following instant will present an impossible set of possibilities because the amount of energy in a given space is limited and the space occupied by the object at that instant is finite. This assumes that there must be enough energy in each time line to accommodate the presence of the object.

Or on the other hand are the MWI advocates saying that is not the case because each time line shares the energy and doesn't need to have incremental energy for multiple time lines even though the different time lines would diverge?
