String Theory: Two Lookalike Galaxies?

Posted by Eric at 12:27 pm. Filed under: General

RedNova News reports:

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.

Never heard of “String Theory”? Check out PBS’s NOVA site, which includes a link to an exercise where you try to imagine four dimensions.

Brian Greene has a book, The Elegant Universe, which discusses this theory in much more detail, and he has a newer book entitled The Fabric of the Cosmos. Part of the Amazon editorial review says:

Assuming an audience of non-specialists, Greene has set hi mself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. For the most part, he succeeds.
