The Multiverse is a concept with more than one meaning and with breathtaking implications on the understanding of the natural laws that govern reality. This documentary tries to explain one of the most recent developments in theoretical physics. Although the concept of the Multiverse (or meta-universe, metaverse) was first introduced in the beginning of the 20th century, the later experiments done with single particles (photons, electrons, even molecules) convinced the vast majority of physicists working in fields like String Theory and Quantum Mechanics of the very high chance that this concept could in fact reflect the true nature of reality.

Level 1 Multiverse: This multiverse is just an extension of our own infinite Universe (see WMAP for evidence for infinite and flat Universe), it is part of our Space but distanced so far away that light from it will never reach us. Max Tegmark estimates that such a Universe, similar to ours, should be about 10^10^115 meters away from our Universe.

Level 2 Multiverse: This Multiverse is made of an infinite number of giant soap bubbles that float in hyperspace (the bulk). Each bubble contains an entire universe. In the infinite vastness of the hyperspace there are an infinite number of bubbles containing a Universe like the one we are living in, and a infinite variety of other Universes. What is more interesting is that these bubbles spawn new baby universes by colliding with each other creating a hierarchy of universes, a tree of Universes. You can imagine this tree equivalent to the tree-of-life but with the fruits and branches replaced by Universes and baby Universes.

Evidence supporting the possible existence of a Type 2 Multiverse comes from the theoretical science field of String Theory. String Theory states that all the constituents of matter, protons, neutrons, electrons, neutrinos, all of them, are made of tiny vibrating strings that oscillate at different frequencies. String Theory predicts the existence of 11 dimensions, as opposed to the 3 (4 with the time dimension), necessary for the strings to vibrate and emerge into what we know as matter and reality. Additionally, the M-Theory (a further development of string theory) predicts the existence of vibrating membranes. More to that, theoreticians say our universe may be a giant membrane, in the bulk (hyperspace) of the Type 2 Multiverse, vibrating in these 11 dimensions.

Some Big Bang theorists speculate on the idea that our Universe began when two such giant membranes (M-brane) collided with each other some 13.75 billion years ago.

Level 3 Multiverse: Quantum mechanics predicts, and indeed experiments done on single particles provide the evidence, that each constituent of matter can find itself in several places at the same time (see Double-slit experiment). When you zoom in to the quantum level everything becomes foggy. Yes, every particle is to be found in several dimensions (universes) at the same time, that is, in several universes that are in the same space and time as our universe but from other dimensions inaccessible to us. There is a parallel universe out there where you don’t read this article or you may have never been born.

Level 4 Multiverse: The Type 4 Multiverse contains all universes resembling our own, but also includes those having physical laws different from ours. The vast majority of the universes with these tweaked laws of physics may not be able to harbor life at all and probably are dull dark places with nothing interesting to show.
