A New Theory of Everything?

The Telegraph is running a story about a new Unified Theory of Physics. Garrett Lisi has presented a paper called An Exceptionally Simple Theory of Everything which unifies the Standard Model with gravity — without using string theory. The trick was to use E8 geometry which you may remember from an earlier Slashdot article. Lisi's theory predicts 20 new particles which he hopes might turn up in the Large Hadron Collider — via Slashdot
