Professor Skip Garibaldi profiled on Emory's eScienceCommons

Rock climber takes on surfer's theory

The “exceptionally simple theory of everything,” proposed by a surfing physicist in 2007, does not hold water, says Emory mathematician Skip Garibaldi.

Garibaldi, a rock climber in his spare time, did the math to disprove the theory, which involves a mysterious structure known as E8. The resulting paper, co-authored by physicist Jacques Distler of the University of Texas, will appear in an upcoming issue of Communications in Mathematical Physics.

“The beautiful thing about math and physics is that it is not subjective,” Garibaldi says. “I wanted a peer-reviewed paper published, so that the scientific literature provides an accurate state of affairs, to help clear up confusion among the lay public on this topic.”

In November of 2007, physicist Garret Lisi published an online paper entitled “An Exceptionally Simple Theory of Everything.” Lisi spent much of his time surfing in Hawaii, adding an alluring bit of color to the story surrounding the theory. Although his paper was not peer-reviewed, and Lisi himself told the Daily Telegraph that the theory was still in development and he gave a "low" likelihood to the prediction, the idea was widely reported in the media, under attention-grabbing headlines like “Surfer dude stuns physicists with theory of everything.”

Garibaldi was among the skeptics when the theory hit the news. So was Distler, a particle physicist, who wrote about problems he saw with Lisi’s idea on his blog. Distler’s posting inspired Garibaldi to think about the issue more, eventually leading to their collaboration.

Lisi’s paper centered on the elegant mathematical structure known as E8, which also appears in string theory. First identified in 1887, E8 has 248 dimensions and cannot be seen, or even drawn, in its complete form.E8-inspired graph. Credit: Wikimedia Commons, J. G. Moxness, an emulation of a hand-drawn original by Peter McMullen.

The enigmatic E8 is the largest and most complicated of the five exceptional Lie groups, and contains four subgroups that are related to the four fundamental forces of nature: the electromagnetic force; the strong force (which binds quarks); the weak force (which controls radioactive decay); and the gravitational force.

In a nutshell, Lisi proposed that E8 is the unifying force for all the forces of the universe.

“That would be great if it were true, because I love E8,” Garibaldi says. “But the problem is, it doesn’t work as he described it in his paper.” As a leading expert on several of the exceptional Lie groups, Garibaldi felt an obligation to help set the record straight.

“A lot of mystery surrounds the Lie groups, but the facts about them should not be distorted,” he says. “These are natural objects that are central to mathematics, so it’s important to have a correct understanding of them.”

Using linear algebra and proving theorems to translate the physics into math, Garibaldi and Distler not only showed that the formulas proposed in Lisi’s paper do not work, they also demonstrated the flaws in a whole class of related theories.

“You can think of E8 as a room, and the four subgroups related to the four fundamental forces of nature as furniture, let’s say chairs,” Garibaldi explains. “It’s pretty easy to see that the room is big enough that you can put all four of the chairs inside it. The problem with ‘the theory of everything’ is that the way it arranges the chairs in the room makes them non-functional.”

He gives the example of one chair inverted and stacked atop another chair.

“I’m tired of answering questions about the ‘theory of everything,’” Garibaldi says. “I’m glad that I will now be able to point to a peer-reviewed scientific article that clearly rebuts this theory. I feel that there are so many great stories in science, there’s no reason to puff up something that doesn’t work.”

Mathematics Faculty of Distinction
news Published Date: 2009-12-01
Emory University intends to make two or more distinguished faculty appointments in Mathematics, under the newly launched Science Faculty Distinction program. This initiative, part of Emory’s strategic plan to enhance faculty excellence, aims to significantly strengthen the basic sciences and mathematics by recruiting a number of outstanding scholars in select disciplines. The first such hiring focus will be in areas related to Computational Number Theory, broadly defined, and will contribute to a transformative change in the department of Mathematics and Computer Science. A guiding principle is for the new faculty members to add significant new strengths while enhancing and bridging existing areas of scholarship within MathCS. New faculty will complement existing areas of excellence within the department, build key connections to the physical and natural sciences at Emory and link to closely related strategic endeavors such as the Computational and Life Sciences initiative.

We invite nominations and applications from outstanding scholars who are internationally renowned scientific leaders within their fields. Candidates must have a PhD in a relevant discipline, a stellar record (and continued promise) of exemplary accomplishment in research, and a commitment to excellence in teaching. Appointments are subject to final funding approval, and are expected to be at the tenured Associate or Full Professor level. However, truly exceptional candidates at all levels will be considered. We invite queries both from individuals and from small teams of collaborating scholars who bring complementary strengths to the Science Distinction initiative. Women and underrepresented minorities are especially encouraged to apply. Applications consisting of a cover letter, CV, research and teaching statements, and three letters of recommendation directly from recommenders should be submitted via Informal inquiries are also invited by email ( Screening begins December 1, 2009 and will continue until all positions are filled.

Raman Parimala to give invited plenary lecture at International Congress of Mathematicians 2010
news Published Date: 2009-11-30
Asa Griggs Candler Professor of mathematics Raman Parimala has been invited to deliver a plenary address at the International Congress of Mathematicians in Hyderabad, India, in August 2010. Parimala has previously given a regular invited address at ICM 1994 in Zurich. That was already an honor, but being invited to give a plenary address is more so: only about 20 mathematicians are selected to give a plenary address at each quadrennial conference. The ICM is the largest conference onmathematics and is hosted by the International Mathematical Union. The most prestigious recognitions, including the Fields Medal, are awarded at this event, in which the most important research contributions are presented by leading mathematicians.
