String Theory
RedNova News - Space - Finding the Ultimate Theory of Everything:
"Could two lookalike galaxies, barely a whisker apart in the night sky, herald a revolution in our understanding of fundamental physics? Some physicists believe that the two galaxies are the same - its image has been split into two, they maintain, by a 'cosmic string'; a San Andreas Fault in the very fabric of space and time.
If this interpretation is correct, then CSL-1 - the name of the curious double galaxy - is the first concrete evidence for 'superstring theory': the best candidate for a 'theory of everything', which attempts to encapsulate all the phenomena of nature in one neat set of equations. "
