It is a common belief that our universe is the only one, But, according to some of the most brilliant minds on the planet this is not true and I too personally believe in the concept of "MULTIVERSE". Now, first of all, the basic factor regarding all this is Inflation. We know that our Universe is expanding. The WMAP satellite has experimentally confirmed this fact. All this is leading to a new cosmological picture of our universe.
According to the "Inflationary Universe Theory", a major refinement of the big-bang theory, first proposed by physicist Alan Guth of MIT , in the first trillionth of a trillionth of a second, a mysterious antigravity force caused the universe to expand much faster than originally thought. This inflationary period was unimaginably explosive, with the universe expanding much faster than the speed of light. (This does not violate Einstein's dictum that nothing can travel faster than light, because it is empty space that is expanding. For material objects, the light barrier cannot be broken.) Within a fraction of second, the universe expanded by an unimaginable factor of 10^50.
The Inflationary universe, although consistent with the practical data, still does not answer the question : What caused inflation? Till now we have been trying to find an answer but its still unanswered.
Because no one knows precisely how inflation started, there is always the possibility that the same mechanism can take place again - that inflationary explosions can happen repeatedly. This is the idea proposed by Russian physicist Andrei Linde of Stanford University. According to this "Multiverse" theory, a tiny patch of a universe may suddenly inflate and "bud", sprouting a "daughter" OR "baby" universe which may inturn bud another baby universe, with this budding process continuing forever. In this way universes may be continually giving birth to new universes. In this scenario, big bangs have been happening continually. Thus, we may be living in a sea of "Multiverse" or "Megaverse".
