Cosmic bubble collisions provide an important possible observational window on the dynamics of eternal inflation. In eternal inflation, our observable universe is contained in one of many bubbles formed from an inflating metastable vacuum. The collision between bubbles can leave a detectable imprint on the cosmic microwave background radiation. Although phenomenological models of the observational signature have been proposed, to make the theory fully predictive one must determine the bubble… Expand
Simulating the universe(s) II: phenomenology of cosmic bubble collisions in full General Relativity
Observing the relics of collisions between bubble universes would provide direct evidence for the existence of an eternally inflating Multiverse; the non-observation of such events can also provideExpand
Simulating the universe(s): from cosmic bubble collisions to cosmological observables with numerical relativity
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.Expand
Simulating the Universe(s) III: Observables for the full bubble collision spacetime
This is the third paper in a series establishing a quantitative relation between inflationary scalar field potential landscapes and the relic perturbations left by the collision between bubblesExpand
Cosmic Bubble Collisions Observable Signature of A Classical Transition
The theory of inflation was introduced to resolve many existing observational problems in cosmology. Inflation becomes eternal when a region of space continuously spawns noninflation regions. ThisExpand
Multiple cosmic collisions and the microwave background power spectrum
Collisions between cosmic bubbles of different vacua are a generic feature of false vacuum eternal inflation scenarios. While previous studies have focused on the consequences of a single collisionExpand
Observable Signatures of a Classical Transition
Eternal inflation arising from a potential landscape predicts that our universe is one realization of many possible cosmological histories. One way to access different cosmological histories is viaExpand
Analyzing Cosmic Bubble Collisions
We develop a set of controlled, analytic approximations to study the effects of bubble collisions on cosmology. We expand the initial perturbation to the inflaton field caused by the collision in aExpand
Gravitational waves from cosmic bubble collisions
Cosmic bubbles are nucleated through the quantum tunneling process. After nucleation they would expand and undergo collisions with each other. In this paper, we focus in particular on collisions ofExpand
Cosmic bubble and domain wall instabilities III: The role of oscillons in three-dimensional bubble collisions
We study collisions between pairs of bubbles nucleated in an ambient false vacuum. For the first time, we include the effects of small initial (quantum) fluctuations around the instanton profilesExpand
Numerical Relativity and Astrophysics
Throughout the Universe many powerful events are driven by strong gravitational effects that require general relativity to fully describe them. These include compact binary mergers, black holeExpand
