Browsing NewScientist I saw this article and thought it was pretty good.  Talks about the current contenders for the theory of everything, not super complicated and if you’re interested in science you’ll love this. 🙂

The “theory of everything” is one of the most cherished dreams of science. If it is ever discovered, it will describe the workings of the universe at the most fundamental level and thus encompass our entire understanding of nature. It would also answer such enduring puzzles as what dark matter is, the reason time flows in only one direction and how gravity works. Small wonder that Stephen Hawking famously said that such a theory would be “the ultimate triumph of human reason – for then we should know the mind of God”.
