Thanks for the reply!
IMHO, string theory is the conspiracy theory of maths.
Yeah, the article actually mentioned that string theory is still not a mainstream theory among physicists. I probably should have included that in my summary, too.
Personally, they lose me when they go beyond 4 dimensions. I get the mathematical concept, but my mind just isn't equipped to even understand what that would mean in the physical world.
They lose me when they get to 22.
