It is a known fact that, throughout the vast universe, there are stars with large enough mass to be capable of collapsing upon themselves. It is during these catastrophic implosions that new, still virtually unknown, entity known as a 'black hole'. It is thought that within these 'black holes' there is a point called a "singularity", on which all physical laws are thought to cease.
In the singularity, the curvature of space and time becomes infinite. Something that, even with the most advanced pieces of modern technology, human's cannot begin to comprehend. Even Einstein's theory of relativity, one of humanity's more intricate points of reference, cannot determine what sort of effect singularity will have on an object, forming an uncertainty of the unknown throughout our universe.

It is from this uncertainty that many more theories have arisen surrounding singularity. Theories such as the existence of tunnels to other worlds, or perhaps even universes, beyond these unstable points. These "wormholes" could be the key to interstellar travel, or in some regards, the key to meeting other life.

However, several flaws and complications surround this theory. Most notably is the fact that the gravitational force of a black hole would crush any interstellar spacecraft within milliseconds of it entering a black hole's range, which is a necessary factor that needs to be accounted and adjusted for, no matter how long it would require, be it decades, centuries, or, quite possibly, millennia.
Nonetheless, while this theory about singularity is questionable, at best, and will likely be left as another simplistic idea of science fiction, there is another, more widely renown, theory about the center of a black hole that has been gaining more acceptance from several respected physicists and specialists throughout the world. One that gives to us, a whole new view about our known universe in its entirety.

Within the point of singularity, it has been agreed that it is impossible to predict physical behavior. This could mean that, beyond this point of singularity there, may be an entirely new set of physical laws. It is quite possible that, after singularity, there may be an absence of such basic forces as gravity, electromagnetism, and even the existence or function of strong and weak nuclear forces. If this were to be proven true, if just one of these forces did not exist or was changed, then technically, it would no longer be a part of this universe.

Our universe is defined as the observable, if not explainable, aspects of the cosmos that involve the galaxies, stars, planets, and life that we know. Should a basic component of our physical laws be changed, none of what we know would exist any longer.
According to a well known text by the name of 'Before the Beginning', by Sir Martin Rees, 'If nuclear forces were slightly weaker, no chemical elements other than hydrogen would be stable, and there would be no nuclear energy to power stars. But, if the nuclear forces were slightly stronger than they actually are, relative to electric forces, two protons could stick together so readily that ordinary hydrogen would not exist, and stars would evolve quite differently.'

This demonstrates the small chance that it took for things to actually turn out as they did, and implies that it may be difficult for things to ever duplicate themselves should this idea of a "Multiverse" ever prove to be more than just a theory.

As of recently however, this Multiverse theory has been widely accepted, further describing the continuous formation of, not just worlds, but universes, through the collapse of stars and the formation of black holes. With each of these black holes there is a new point of singularity, and in term, a new possible universe. As Rees describes it, 'Our universe may be just one element - one atom, as it were - in an infinite ensemble: a cosmic archipelago. Each universe starts with its own big bang, acquires a distinctive imprint (and its individual physical laws) as it cools, and traces out its own cosmic cycle. The big bang that triggered our entire universe is, in this grander perspective, an infinitesimal part of an elaborate structure that extends far beyond the range of any telescopes.'
This puts our place in the Multiverse into a much smaller spectrum for all of human-kind. While the size of the earth in relation to the sun is minuscule, the size of the sun, the solar system, the galaxy, and even the universe, could pale in comparison to this proposed 'Multiverse'. It would be a shift in thinking that may help explain big bang theory, and quite possibly give light to the idea of parallel universes, and even the creation of life itself.

While the idea of a parallel universe may sound farfetched, a recent book from an Oxford physicist named David Deutsch entitled, 'The Fabric of Reality: The Science of Parallel Universes - And Its Implications', describes the possibilities of tapping into these parallel universes. He proposes that, through a parallel universe, one would be able to find an identical counterpart to themselves within the other universe, and collaborate with it to increase knowledge of the each other's reality's. This involves the collaboration of many theories that, as of yet, do not have much proof to them.
However, it is still another branch of the Multiverse theory that has become widely accepted in recent years that could possibly yield positive benefits for society, both ours, and that of the parallel society's.

The Multiverse theory itself, regardless of parallel universes, has many implications. Most notably is the unique, complex process from which our own universe was born, and how easily it could have been different. It may imply that, out of the possibly thousands, millions, or even billions of universes, ours was unique enough to develop life, which in itself is special. Perhaps life in another universe has a different meaning, but we know that our universe, at the very least, is special, in that, it houses our kind of life.
If just one physical law were slightly different, then there would be nobody to appreciate the beauty that we can see on an everyday basis. This brings up one ultimate question though. If every universe began from another universe, where precisely did it all begin? Recent physicists imply that there is no room for a creator under the current model of thinking. However, with such a complex system of laws, principles, and forces that allowed life to exist in the first place, one must never give in to the possibility of there not being a creator behind it all.
