Superstrings
When particles become so small that they approach the smallest possible size in the Universe, something strange happens. They become multi-dimensional rubber strings.

In quantum physics, there is a measurement known as the Planck Scale (10^-35 meters). This is, to make it short, the tiniest space which any object can fill before it becomes pure energy.
At this scale, something strange happens to the laws of physics. Instead of just disappearing into oblivion, objects at this scale become multidimensional strings which represent all the properties of the object. By vibrating, twisting and turning in all dimensions, this so-called superstring actally exists on the border of space and time. And four dimensions are not enough: superstring theory demand at least 11 different dimensions to work.
Strange as it may sound, this implies that superstrings are objects which exist outside our perception of space-time. These cosmic guitar strings seem to create a harmony consisting of ripples through time.
And the fascinating possibility is that these vibrations may actually bring together all the observed forces in the universe: gravity, electromagnetism, and the strong and weak forces (the forces which hold an atom together).
The superstring theory is controversial, and so far this is a purely theoretical matter. But by studying superstrings, scientists may eventually find a theory which can explain everything we observe in the Cosmos.
