As we look up into the stars we may not be able to what lays ahead in it's outer limits, or what may be beyond that, but we do have our theories for this universe, and through science even peruse what may lie ahead in he multiverse.
What is The Multiverse?
The multiverse is the hypothetical set of infinite or finite possible universes (including the historical universe we consistently experience at this present momment!) that together makes up everything that exists and can exist: space, time, matter, and energy as well as the physical laws that describe there uses towards it's surroundings. various universes within the multiverse are sometimes called parallel universes. Meaning, any momment in time can create or generate multiplicative amount of Parallel timelines, therefor enerating a universe (theoretically).
What are the Elements of the Multiverse
Cosmologist Max Tegmark has provided a taxonomy of universes beyond the familiar observable universe. The levels according to Tegmark's classification are arranged such that subsequent levels can be understood to encompass and expand upon previous levels; Starting with our own universe slowly graduating outer cosmical, than outer dimensional.
Level I: Beyond our cosmological horizon
Level II: Universes with different physical constants
Level III: Many-worlds interpretation of quantum mechanics, and
Level IV: Ultimate ensemble
Another favourable theory is Blackhole Cosmology. A black-hole cosmology is a cosmological model in which our known universe is an entryway of a black hole existing as one of possibly many inside a larger universe.
Is the Multiverse Important.
though the study of the Multiverse is heavily funded there has been a lot of criticism in the field of science as to the possibility of there being a multiverse.
This article from the website "Scientific American" deals with the controversy the theory has http://www.scientificamerican.com/article/does-th...
Another argument comes from Paul Davies who offers a variety of arguments that multiverse theories are non-scientific
"For a start, how is the existence of the other universes to be tested? To be sure, all cosmologists accept that there are some regions of the universe that lie beyond the reach of our telescopes, but somewhere on the slippery slope between that and the idea that there are an infinite number of universes, credibility reaches a limit. As one slips down that slope, more and more must be accepted on faith, and less and less is open to scientific verification. Extreme multiverse explanations are therefore reminiscent of theological discussions. Indeed, invoking an infinity of unseen universes to explain the unusual features of the one we do see is just as ad hoc as invoking an unseen Creator. The multiverse theory may be dressed up in scientific language, but in essence it requires the same leap of faith."

Theories About the Multivers
Model Realism: Possible worlds are a way of explaining probability, hypothetical statements and the like, and some philosophers such as David Lewis believe that all possible worlds exist, and are just as real as the actual world (a position known as modal realism).
Fictional Realism: The view that because fictions exist, fictional characters exist as well. There are fictional entities, in the same sense in which, setting aside philosophical disputes, there are people, Mondays, numbers and planets.
Traveling Through the Multiverse
If we were to travel through the multiverse we would travel both space and time, that can be our past, future or even events that have not occured through our own timeline! This means any action that you have taken can trigger a collasal amount of events that lead to multiple universes. To travel, we must journey through either a Blackhole (bringing back the topic of blackhole cosmology) or rough a wormhole, which is a cosmic bridge that an link different parts of space and time together through means that many scientists can only theorise. Though this would an amazing eat, this could cause major errors in the space time continuum, disrupting multiple timelines and events that can do more harm than good.
