83. Quintessence on the string theory landscape?
Nemanja Kaloper and Lorenzo Sorbo have recently released a paper explaining how the quintessence can be realized on string theory landscape. What is quintessence and why the question is important? (…)
80. Watching worlds collide: bubbles, bubbles, bubbles
Getting tired of malicious attacks by anti-landscapists, Spencer Chang, Matt Kleban and Thomas Levi released a paper about one observable effect on string theory landscape. (…)
69. Happy Halloween!
Since it is Halloween, today’s story is about ghosts…
Let us follow the analysis of massive gravity theory in de Sitter background by Izumi and Tanaka. (…)
58. Stability of de Sitter space: dS as a perfect interferometer
Let us now show that QFT of a massive scalar field in de Sitter space features instabilities if the number of dimensions is odd. (…)
57. Stability of de Sitter space: statement of the problem 1
Ok, friends, I feel that the time has come to let you know about things I am currently involved in – namely, understanding of intrinsic stability of the de Sitter space. (…)
