21. About probabilities in cosmology (and general) and in stochastic inflation in particular
Discussion was initiated by the question “what is the physical meaning of time 
in vacuum dynamics equations” that was smoothly transformed into the question “what is the meaning of probability 
in the vacuum dynamics equations”. My answer was that is the world time for the 4-dim observer and is the probability for him to measure a given value of the cosmological constant. Lubos replied:
20. More on KS throat cloaking…
Was thinking about recent paper by Alex Buchel and Lev Kofman… and found that I have a couple of naive questions:
1) cloaking is 5 dim picture (well, 10-dim) - i.e., throat for bulk CY observer is seen as AdS black hole. (…)
19. Disorder on the landscape: non-technical intro
Today I will kindly allow myself a bit of selfpromotion As I said yesterday, our paper “Disorder on the landscape” is finally out (by the way, Lubos Motl already has a very nice post about it on his blog). (…)
18. Eye on ArXiv: 15 Apr 2008 - Transplanckian physics, brane cosmology and holographic mesons
Sorry for being quiet for so long. The reason is we were finising a paper, asked for comments and got a lot of them. The paper is finally submitted to appear on ArXiv in tomorrow’s listings. (…)
15. Anderson localization. Just crossed my mind…
I personally consider Anderson localization as one of the most prominent dynamic vacuum selection principles on the string theory landscape. Let me remind you the main idea behind it. (…)
12. Eye on ArXiv: 4 Apr 2008 - KS throat cloaking, non-gaussianity and Mathur’s fuzzballs
1. Alex Buchel, Lev Kofman “Black Universe epoch in string cosmology”
Alex and Lev write about multithroat scenario in string cosmology. (…)
