An Exceptionally Simple Theory of Everything

A man by the name of Garrett Lisi has published an article called "An Exceptionally Simple Theory of Everything" here: http://arxiv.org/abs/0711.0770

There is a great write up on it here: http://www.telegraph.co.uk/core/Content … =30&page=0

Re: An Exceptionally Simple Theory of Everything

It doesn't seem to be saying anything new till you get to the end:

The theory has no free parameters. The coupling constants are unified at high energy, and the cosmological constant and
masses arise from the vacuum expectation values of the various Higgs fields,

Which is pretty cool, if this survives peer review.

And the fact that it doesn't require more than 4 dimensions.

Re: An Exceptionally Simple Theory of Everything

Wow, I got the whole PDF of his theory from MIF's first link (on the right of the web page)
Way over my head probably for my whole life, unless I get struck with some serious ability to learn more.

Re: An Exceptionally Simple Theory of Everything

Here is an explanation of "E8": http://aimath.org/E8/e8.html

I only have a vague idea of Lie groups, they are kind of like groups that also need to be continuous. Maybe Ricky can help us out here!
