Since the 1960s (the dawn of String Theory) Theoretical Physicists have been examining the complex structure of one of the most 'profound' theories to be developed by Mankind - String Theory. In 50 years the Theoretical Physicists working on this field have developed it further and have been able to understand the various perplexing ideas that underly this theory. As everyone would know in 1995 the theory was drastically redefined and a new spark of interest was ignited. It has been 15 years since the creation of M-theory and my questions are: Is M-Theory still in a state of obscurity? Do we understand how it relates to the physical world? Has there been any paradigm shift in how we see this theory? And finally, what dilemmas does this theory present that makes it so difficult to understand?
