That's two questions.
It is simply called "Universe" which derives from a Latin phrase roughly meaning "everything rolled into one". Some multiverse/omniverse theorists tend to give names to our universe as an identifier. It's also common in science fiction to give the universe a name.
this whole universe is imperfect therefore, man is incomplete and wants to be completed..
3, or perhaps more. It depends on the theory to which you ascribe. For example, recent research done at the Princeton Institute for Advanced Studies (IAS) led to the creation of ekpyrotic theory. According to ekpyrotic theory, our universe and its creation stems from the collision of two "branes" that could theoretically and literally represent parallel universes. According to Julian Barbour, an infinite number of parallel universes exist, since every time a decision is made on either the microscopic or macroscopic level, a bifurcation is created leading to the birth of a new "universe". Long answer short, minimally 2 parallel universes, maximally infinit.

Currently, scientific evidence suggests that the universe is expanding rather than contracting.
The Geocentric or Ptolemaic Model put the earth at the center of the Universe. The Heliocentric Model postulated by Copernicus and, before him, Aristarchus, places the Sun at the center of the Solar System. Galileo's observations proved the validity of the Heliocentric Model.
There are currently no known means to actually separate parts of the universe physically from the rest of the universe.
We do not know. Certainly current THEORIES suggest that dark energy is causing the universe to expand at a faster and faster rate. Its existence is postulated to explain why we can observe that the universe is expanding at an accelerating rate. However, we do not know what dark enery is (if it exists).
Lego universe will be launched in the seccond half of 2010. Beta testing is currently going on.
That depends on whether the Universe itself is infinite. It is not currently known whether this is the case.
It is believed that the Universe is much, much bigger than the observable Universe, but exactly how much bigger is not currently known.It is believed that the Universe is much, much bigger than the observable Universe, but exactly how much bigger is not currently known.It is believed that the Universe is much, much bigger than the observable Universe, but exactly how much bigger is not currently known.It is believed that the Universe is much, much bigger than the observable Universe, but exactly how much bigger is not currently known.
What is known as the Big Bang Theory is the currently recognized model of how the universe began.
