From a very very brief http://www.newscientist.com/article...god-seven-theories-of-everything.html?page=1"of seven competing theories for a Theory of Everything:
from New Scientist: 15:33 04 March 2010 by Michael Marshall
1. String theory
2. Loop quantum gravity
3. Causal dynamical triangulations (CDT)
4. Quantum Einstein gravity
5. Quantum graphity
6. Internal relativity
7. E8
Doing a search on numbers 3 - 6 on PF Forum does not result in a great number of hits.
Could those "in the know" about CDT, Quantum Einstein gravity, Quantum graphity, and Internal relativity list a bit more detailed summary of the major strengths, weaknesses of each of these theories ?
Thanks in advance...

Edit: Thanks Justin/Tom I should have known better, than to qualify the heading in my post, and that 2 - 6 were quantum theories of gravity and in fact NOT a theory of everything. I wanted to see if PF members who work in any of items 3 - 6 above have any insight or opinions on them. I may send a link to this thread to the editorial staff at: New Scientist as to their choice of words for their article.
