Reconstructing the Universe with secondary CMB anisotropies
Speaker(s): Matthew Johnson
Abstract: The cosmic microwave background radiation has been an indispensable tool for learning about the origins and evolution of our Observable Universe. Satellites and ground based experiments measuring the temperature and polarization anisotropies with ever increasing angular resolution and sensitivity ha... read more

Searching for Other Universes
Speaker(s): Matthew Johnson
Abstract: Centuries of astronomy and cosmology have led to an ever-larger picture of our ‘universe’ — everything that we can observe. For just as long, there have been speculations that there are other regions beyond what is currently observable, each with diverse histories and properties, and all inhab... read more

Abstract: The theory of eternal inflation in an inflaton potential with multiple vacua predicts that our universe is one of many bubble universes nucleating and growing inside an ever-expanding false vacuum. The collision of our bubble with another could provide an important observational signature to test th... read more

First Observational Tests of Eternal Inflation
Speaker(s): Matthew Johnson
Abstract: Inflation, a postulated epoch of accelerated expansion in the early universe, has become a principal component of the standard model of cosmology. From a wide variety of initial conditions, inflation produces a nearly homogeneous universe populated by density fluctuations that seed large-scale struc... read more

Bringing Terminal Vacua Back to Life With Classical Transitions
Speaker(s): Matthew Johnson
Abstract: In this talk, I will describe how the collision of Minkowski or crunching bubbles can re-start inflation in a portion of the bubble interior. Consistent with various singularity theorems, such collisions can only seed a lasting inflationary phase with energy density lower than that of the parent vac... read more

Observational tests of eternal inflation
Speaker(s): Matthew Johnson
Abstract: In the picture of eternal inflation, our observable universe resides inside a single bubble nucleated from an inflating false vacuum. Some of the theories giving rise to eternal inflation predict that we have causal access to collisions with other bubble universes, providing an opportunity to confro... read more

Bubble Nucleation and Eternal Inflation
Speaker(s): Matthew Johnson
Abstract: A number of mechanisms have been introduced in previous literature that might be responsible for transitions between metastable minima in a scalar field theory coupled to gravity. The connection between these transition mechanisms has remained unclear, and current formulations of eternal inflation o... read more
