Query: Universality of the Volume Bound in Slow-Roll Eternal Inflation   It has recently been shown that in single field slow-roll inflation the total
volume cannot grow by a factor larger than e^(S_dS/2) without becoming
infinite. The bound is saturated exactly at the phase transition to eternal
inflation where the probability to produce infinite volume becomes non zero. We
show that the bound holds sharply also in any space-time dimensions, when
arbitrary higher-dimensional operators are included and in the multi-field
inflationary case. The relation with the entropy of de Sitter and the
universality of the bound strengthen the case for a deeper holographic
interpretation. As a spin-off we provide the formalism to compute the
probability distribution of the volume after inflation for generic multi-field
models, which might help to address questions about the population of vacua of
the landscape during slow-roll inflation.
