There are two somewhat separate, but not mutually exclusive notions of the multiverse: on the one hand, in inflation models, many separate pockets of space can expand and form individual causally disconnected patches possibly with differing laws of nature.
On the other, there is the many worlds interpretation of Quantum theory which basically just says, include all observers in the quantum description, and never collapse the wavefunction. Where the copenhagen interpretation which Zen mentions effectively tells you to throw away all superpositions of the observer state except the one which corresponds to the measured outcome, the relative state or many worlds picture lets them all go on as infinite superpositions corresponding to all possible outcomes of all quantum uncertain decisions. Combine this with a picture of the universe where the laws of physics are set randomly by quantum uncertainty, and you get a continuum of parallel worlds superimposed onto ours, some vastly different even in their physics, some only differing in minuscule detail.
Both the inflationary multiverse and many worlds QM could be simultaneously realized, giving you even more of everything.
