Science has progressed a lot as we all know. And its progress seems to have been more rapid in past 100 years. Scientists have been trying to develop more and more advanced grasp of natural law and have been quite successful so far. But........... with a problem. Because of this problem the physicists have been seeing the dark cloud rooming on the sky. And the problem is: As everyone may or may not know, there are two foundation pillars of modern physics on which the complete modern physics rests. One is Quantum Mechanics which provides the theoretical framework for understanding whole universe in the smallest scales from the atoms and molecules to deep inside upto electrons, Protons and quarks. And the other one is the Albert Einstein's one of the most beautiful and extra-ordinary theory called the General Theory of Relativity, which defines the universe in the theoretical framework of largest possible scales like stars, galaxy, clusters and way beyond the super clusters. Now, when these two theories are compared to one another with both leads to each others very disturbing conclusions that they are not at all compatibles to each others. What I mean to say is, as both have undergone for so massive amount of progress in each field with very accurate results all the time when tested individually, that have explained the expansion of whole universe and also the smallest fundamental particles of the nature but despite all these facts, they both cannot be right!!!!! And the reason why you think that would have happened is because a physicists either goes on to study about the largest scale or the smallest scale. So, there has been a long existed problem in this part.
But as we know, the universe could be extreme. When we see all the phenomenon in this universe, from the big bang to day, the super powerful black holes, the giant structures, the particles that are trillion times smaller than an stom and so on we will say that the universe is really extreme. So, here's the question - so does that mean that it is possible that universe is divided into two, which requires one set of principle to describe when things are huge and requires another set of principle when things are small?
When some one asks this question, a very young theory in physics compared to the vulnerable edifices of quantum mechanics and general relativity, which is called the SuperString theory would answer you a bold and concrete NOO!!!
