Are Parallel Universes the Key to Understanding the Multiverse Theory?

[shyam1993]

The multiverse is a theory in which our universe is not the only one, but states that many universes exist parallel to each other. These distinct universes within the multiverse theory are called parallel universes. A variety of different theories lend themselves to a multiverse viewpoint.

As far as i have heard and read, the existence of parallel universes is not a surprise and that the fundamental laws of the "nature" that is the nature of "our Universe " do not apply over there. Some believe that the parallel universe is co-existent with ours- that is the particles of both the universes are in the same space but cannot interact with each other since they all move at relative speeds greater than that of the speed of the light. In such a universe the effect precedes the cause, unlike our universe, it is a direct consequence of the special theory of relativity.

Yes, and in all of those universes there are creatures which are trying to advertise and sell their crackpot books.

There are many multiverse theories. It's predicted that the parallel universes are exactly like ours but differ in very tiny variables or gigantic factors like the laws of nature. Some of these universes are said to be in a higher dimension.

Saw an interesting talk by Michio Kaku yesterday on the internet in which he said that one of the far-out hypotheses now is that maybe parallel universes are the source of the gravity that we see as dark matter. I have not the knowledge to even judge whether this is just silly or not, but based on what I have read of cosmology, it can get pretty hard to tell whether or not something is silly and it is at least interesting.
