Could you please explain it to me? Also, please try to use examples where you have to, rather than analogies - they don't help.

Many Worlds is an interpretation of quantum Mechanics.
http://en.wikipedia.org/wiki/Interpretat…
We do not “understand” QM, we “Interpret” it. We form mental pictures of what is going on and they are weird because QM is weird. The Interpretations may not be “reality.” Consider Schrondinger's Cat (Google it if you don't know it.) Lets consider 2 ways of looking at the outcome:
Copenhagen: There is a 50 - 50 chance that the cat is dead, so until we look and find out, the cat exists in this world as both dead AND alive at the same time. When we look we find the cat alive OR dead. What ever we find, that is it and the cat is in that state and that is it alive or dead
Many Worlds: The experiment creates 2 universes. In one, the cat is alive. In the other, the cat is dead. When we look, we find out which universe we live in, the one with a live cat or the one with a dead cat. Both, exist, so there exists a universe where the cat is always alive. Google Quantum Suicide/Immortality for farther discussion.
Multi-verse is a theory from Cosmology to explain the origin of the universe
Creation of the Universe
We make the assumption that there is a "hyper Spacetime" that has always existed.
Someone or something has always existed
God has always existed
Space-time has always existed
Both statements are equally valid. Take your choice.
Anyhow:
Spacetime is not nothing. It has properties, it can be bent, warped, twisted. Spacetime has structure. Spacetime is pervaded by Dark Energy. In fact, Dark Energy may be the structure of Spacetime, what we call the "Fabric of Spacetime
So, we have a huge amount of energy stored in the Fabric of Spacetime. A quantum fluctuation releases some of that energy as a Big Bang creating a universe. It is all a matter of scale This process has gone on in the past and continues today creating an infinite number of universes. We see the Big Bang not as a unique event, but as a regular event that fits with a logical, consistent physical process. Physics makes the most sense without unique events. A physics that allows unique events is unpredictable and borders on magic.
