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. (…)
73. How eukaryotic cells feel direction
Eukaryotic cells present in both plants and animals are cells bounded by membranes and containing nuclei. (…)
55. Eternal inflation: stochastic approach 3 (Inflationary perturbations 7)
Last time we have found that dynamics of the inflaton field (more precisely, its expectation value w.r.t. to the distribution among different Hubble patches) is determined by the Langevin equation. (…)
54. Eternal inflation: stochastic approach 2 (Inflationary perturbations 7)
In the previous post we have started to discuss the regime of eternal inflation realized when classical displacement of the inflaton field becomes comparable with the average amplitude of fluctuations generated at super-Hubble scale. (…)
53. Eternal inflation: stochastic approach 1 (Inflationary perturbations 7)
In this post I start to discuss physics of eternal inflation - regime where superhorizon cosmological perturbations become of the order 1.
