A review paper by Bobby Samir Acharya, Gordon Kane and Piyush Kumar http://arxiv.org/pdf/1204.2795v1.pdf 12 April 2012 This is my first post here in a long time. I learned of this paper from yesterday's Lubos Motl blog. It is the most instructive string theory paper I have ever read...

No more crackpot theories. And I thought I was kicked off long ago. Just when I have a real good 26d string cosmology. yanniru

I may be able to help you visualize the compactified dimensions. In my opinion, the most important aspect of compactified space is that it still exists as a discrete subspace throughout all space. Depending on how the original dimension broke up into pieces of space, that subspace could be a...

Thank you for the critique. I just noticed from the paper of Carlos and Diaz that selectrons are charged [http://arxiv.org/PS_cache/hep-ph/pdf/9511/9511421v1.pdf ] I had expected zero charge along with zero spin. I had not considered the energy consideration and was more concerned with pair...

Well, I suppose that's one way to handle "crackpot" ideas

I have been removed from this forum for previous "crackpot" ideas. However, I would appreciate a review of the one presented below. I submit it to this subforum because it is based on superstring theory. Selectrons as the particles of Dark Energy Consider the creation of particle pairs in...

It seems that arivero is contradicting coalquay404 who in answer to my question said that 26-d string theory has only had one time dimension.

I recall that the original 26-d closed string theory had two time dimensions as well as tachyons and was considered undesirable for both reasons. Does anyone have a similar recollection? However, in reading Lisa Randall's book "Warped Passages", the claim is made that 26-d theory has but one...

I am suprised that there is no mention of Lisa randall, etal, in this discussion who postulates that our universe is a 3-d brane in larger dimensions

Specifically LGC is dual to RS theory with an extra (large) time-like dimension, as reported by Parampreet Singh today in: http://arxiv.org/PS_cache/gr-qc/pdf/0603/0603043.pdf This is the first connection between loop quantum gravity and string theory that I am aware of. The need for an...

Chronos or anybody, is it true that there is no DM associated with spherical galaxies? I ask Chrnons because he mentioned that different amounts of DM are expected for different galaxies.

DM Constituents Since I am a layman, I have no right to do this. Nonetheless, I put my money on a mixture of several components: LSP Axions Mirror Matter but hedge my bet with Bekenstein's MOND

Lubos Motl makes fun of this paper on his blog today (i.e., QG & SM) http://schwinger.harvard.edu/~motl/sf/frames.html

Could someone comment on Jakob Bekenstein's last few papers which attribute Dark Matter to theoretical artifact; http://arxiv.org/abs/astro-ph/0412652, http://arxiv.org/abs/astro-ph/0509519, http://arxiv.org/abs/astro-ph/0602266?

Reginald Cahill derived a non-symmetric form of General Relativity from Process Physics [see e.g., http://arxiv.org/abs/physics/0307003] similar to what John Moffat has been publishing for years [see e.g., http://arxiv.org/abs/astro-ph/0506370] and what Jakob Bekenstein recently published [...
