Surfer dude, Garrett Lisi lives in his van on a beach in Maui. Using a type of algebra he calls E8, Garrett has developed an exceptionally simple theory of everything -- a grand unified theory that explains all the elementary particles, as well as gravity. (link to pdf of paper found below)

Lisi describes how gravity, the standard model bosons, and three generations of fermions can be unified as parts of an E8 superconnection. This unified field theory attempts to describe all fundamental interactions that physicists have observed in nature, and stands as a possible theory of everything, unifying Albert Einstein's general relativity with the standard model of particle physics.

"I think the universe is pure geometry - basically, a beautiful shape twisting and dancing over space-time. Since E8 is perhaps the most beautiful structure in mathematics, it is very satisfying that nature appears to have chosen this geometry."

"This is an 'all or nothing' kind of theory -- meaning it's going to end up agreeing with and predicting damn near everything, or it's wrong. At this stage of development, it could go either way." Garrett Lisi

This video explains how mathematics predicts reality

Warning, even though I have a degree in physics education, the material presented was way over my head. I will watch it again though, because it does give me a glimpse of how mathematics can lead to understanding, perhaps even someday making possible something like electrogravity.

31 page paper (pdf) An exceptionally simple theory of everything

Garrett Lisi, a 39-year-old surfer, hiking guide and construction worker (with a PhD in theoretical physics), believes he may have solved the biggest problem in all of science – how are all the particles of matter and forces of nature related to one another? Scientists since Einstein have been trying to figure it out, with little success. (The current theory involves outrageously tiny “strings” vibrating in 11-dimensional space. The mathematics, they say, is beautiful, but it cannot be tested or verified.) Lisi’s breakthrough came when he noticed that the formulas that describe something called the E8 pattern -- a complex, geometrical design with 248 points – also describe many of the fundamental forces and particles. His theory is that nature follows the same formulas as E8, and that the figure can be used to predict particles that have not yet been discovered. If he's right, he will have finally shown that everything in the universe is related, and basically just different manifestations of the same essence.

Rad, dude.
