Yes, entirely different points of space outside our (linear) universe.
You /don't/ move anything when it splits off, of course, they simply
spring, fully formed into being. At every branching this parallel
universe (or these universi) come into being like branches splitting
off of a twig. Don't think of it as an analog process, like
macrocosmically observable phenomena, its a discrete phenomena.
NOT all dimensions interact. For example, it takes significant energy
for me to broach my transportation in our fourth dimention, time; even
then, I can only affect it by compressing the relative passage of my
time and another reference frame's. The dimention in which MWH
universi split is simply defined as being non-interactive.

A quantum event occurs at any time a quantum wave collapses into a
state. Yes, there are a lot of quantum events.
Actually, energy /can/ be borrowed from the sub-quantum `froth'
according to the latest theories. The shorter the amount of time its
borrowed, the more you can have. Theoretically, energy could come
into being in almost any amount purely randomly ... but its
hyper-rare.
