The Big Idea: Roger Highfield explains why Garrett Lisi, the surfer who drew up a ‘theory of everything’ to explain the universe, is a great role. In November of , physicist Garrett Lisi published an online paper entitled “An Exceptionally Simple Theory of Everything.” Lisi spent much. Garrett Lisi has a new paper, “An Exceptionally Simple Theory of Everything.” Many people seem to think that I should have an opinion about it.

Then we have the statement that Jacques changed the subject. Okay, maybe there is a miraculous new way of using loopholes in that theorem to do fun things. If you attack the person and not the view there is no way they are going to be in a mood to listen to you no matter how correct you may or may not be.

### An Exceptionally Simple Theory of Everything – Wikipedia

I recommend that thepry start with the one true force — entropy, and build from there. But since there have been repeated requests, here is what I am thinking about this. Will they just add some epicycles to the theory and claim to be doing science, like Ptolemy did when the epicycle model of the Earth-centred-universe failed to make accurate predictions?

Your response is highly unprofessional, it has no content except a statement of your unwillingness to engage in a scientific discussion based on results in papers. Andy, I agree, I also suspect that the motions we currently see are the result of known matter that simply relates in ways not yet understood, which may be found in the E8 lattice relationship.

Please treat me in the way you wish to be treated. Since even the originator of the original E8 theory agrees it fails this test, there is no need to wait for more analyses. If you want, the assumption is the requirement to be compatible with what we already know, with observations that we have made, and theories we have established.

### Garrett Lisi’s Theory of Everything! – Cosmic Variance : Cosmic Variance

My take on the story broke in The Daily Telegraph in Novemberand has since been viewed more than a million times on telegraph. The theory is presented as an extension of the grand unified theory program, incorporating gravity and fermions. Unfortunately the only link between these universes is Nothing. What would allow that instantly would be if all those who have made nasty or if or negative personal remarks cease them and apologise for them.

The internet makes communication failures even more likely. Photons traveling between bodies moving at speeds relative to one another …. What did Distler contribute? I thought you were a great fan of representation theory. Again, this is the story Lisi has been telling journalists and also writing on his Everyrhing blog.

## An Exceptionally Simple Theory of Everything

Haelfix, you kind of miss my point. The schoolyard taunts about chiral fermions seemed oddly familiar, I just realized why. I hoped it would be recipricated.

They are explicit that for every left handed current in their model there is a parity related right handed current with equal coupling constants. Now do you know the answer eeverything the following question: It is a professional obligation.

One might have thought that my reduction of the issue to a clear-cut mathematical question in representation theory, a question that must have a yes-or-no answer, would have led to a way out of the impass.

Thanks oc your kind words, but wiith respect, this resolved only the point I queried. Dear physics neophyte, In the words of one of your earlier postings, wtf?

This places a huge responsibility on the senior physicists that the journalists consult. If I were a string theorist, I would certainly be interested in explanations of electroweak symmetry breaking that would look maximally dull at the LHC — by which I mean not only no low-energy supersymmetry or Kaluza-Klein modes showing up, but not even a Higgs.

## Research concludes there is no ‘simple theory of everything’ inside the enigmatic E8

Shame it is only the inner circle that will ever hear about those, but such is life. Peter Woit, for you everything is a game of impressions. Thanks for the link.
