Eternal Inflation, Global Time Cutoff Measures, and a Probability Paradox
Alan H. Guth, Vitaly Vanchurin
The definition of probabilities in eternally inflating universes requires a measure to regulate the infinite spacetime volume, and much of the current literature uses a global time…
Towards a kinetic theory of strings
Vitaly Vanchurin
We study the dynamics of strings by means of a distribution function f(A, B, x, t) defined on a 9+1D phase space, where A and B are the correlation vectors of right- and left-movin…
Towards a non-anthropic solution to the cosmological constant problem
Andrei Linde, Vitaly Vanchurin
Many probability measures in the multiverse depend exponentially on some observable parameters, giving rise to potential problems such as youngness bias, Q-catastrophe etc. In this…
Stationary Measure in the Multiverse
Andrei Linde, Vitaly Vanchurin, Sergei Winitzki
We study the recently proposed "stationary measure" in the context of the string landscape scenario. We show that it suffers neither from the "Boltzmann brain" problem nor from the…
Geodesic measures of the landscape
Vitaly Vanchurin
We study the landscape models of eternal inflation with an arbitrary number of different vacua states, both recyclable and terminal. We calculate the abundances of bubbles followin…
Numerical search for a fundamental theory
Vitaly Vanchurin
We propose a numerical test of fundamental physics based on the complexity measure of a general set of functions, which is directly related to the Kolmogorov (or algorithmic) compl…
