What cosmologists try to go to the beginning of understanding the universe itself, our ideas less FI RM. General theory of relativity Einstein provided the theoretical basis for a century of progress in our understanding of the evolution of the universe. But this is contrary to the other pillar of modern physics, quantum theory, the biggest challenge of course is to combine the two. Only with such a Unified theory will be able to very early moments of the universe, the so-called Planck era about 10-43 seconds, comes when the space-time itself is formed.

Preliminary attempts to Unifi ed theory lead to some remarkable speculations about our house. String theory, for example, predicts the existence of extra dimensions of space and possibly other universes floating, more space. What we call the Big Bang of our universe, a collision with another marriage of string theory with the concept of carrying perhaps INFL resulted wildest idea yet, on the one planet, namely that the universe contains some INFI Nite excluded units, each with own local laws of physics.
