If the results of the first LHC run are not betraying us, many decades of particle physics are
culminating in a complete and consistent theory for all nongravitational physics: the standard …

Abstract Models of cosmic inflation posit an early phase of accelerated expansion of the
universe, driven by the dynamics of one or more scalar fields in curved spacetime. Though …

A bstract We study bubble of nothing decays and their reverse processes, the creation of
vacua through 'bubbles of something', in models of the Universe based on string theory …

A bstract We describe a new phenomenon in quantum cosmology: self-organised
localisation. When the fundamental parameters of a theory are functions of a scalar field …

In the picture of eternal inflation as driven by a scalar potential with multiple minima, our
observable universe resides inside one of many bubbles formed from transitions out of a …

A bstract In the multiverse the scale of supersymmetry breaking,\(\widetilde {m}={F_X}/{M_
{*}}\)∗, may scan and environmental constraints on the dark matter density may exclude a …

I describe reasons to think we are living in an eternally inflating multiverse where the
observable'constants' of nature vary from place to place. The major obstacle to making …

To make predictions for an eternally inflating “multiverse,” one must adopt a procedure for
regulating its divergent spacetime volume. Recently, a new test of such spacetime measures …

A bstract Infinities in eternal inflation have long been plaguing cosmology, making any
predictions highly sensitive to how they are regulated. The problem exists already at the …
