Geometry is All

An Exceptionally Simple Theory of Everything"[1] is a physics paper submitted to the arXiv library on Nov. 6, 2007 by Antony Garrett Lisi. His theory claims to unify all fields of the standard model with gravitylattice of E8peer-reviewed or published in a scientific journal, but it has drawn a wide range of professional reaction and stirred public interest in the topic and its author. using a 248-point geometry. The title is a mathematical pun on E8's classification as both a simple group and an exceptional group.

That a theory of everything might emerge from geometry would be neat, but it is a long shot. Nevertheless, that is what Garrett Lisi is proposing. The geometry he has been studying is that of a structure known to mathematicians as E8, which was first recognised in 1887 by Sophus Lie, a Norwegian mathematician. E8 is a monster. It has 248 dimensions and its structure took 120 years to solve. It was finally tamed earlier this year, when a group of mathematicians managed to construct a map that describes it completely.

What a refreshing leap of faith rewarded that a contemporary ronin physicist would posit an outrageous construct taken straight from the most archetypal depths of sacred geometry as a grand unified theory of everything.....,
