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 bubbles produced during eternal inflation. We introduce a new method for computing cosmological observables from numerical relativity simulations of bubble collisions in one space and one time dimension. This method tiles comoving hypersurfaces with locally-perturbed Friedmann-Robertson-Walker coordinate patches… 
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 via
Black hole formation from the collision of plane-fronted gravitational waves
This paper introduces a new effort to study the collision of plane-fronted gravitational waves in four dimensional, asymptotically flat spacetime, using numerical solutions of the Einstein equations.
A numerical relativity scheme for cosmological simulations
Cosmological simulations involving the fully covariant gravitational dynamics may prove relevant in understanding relativistic/non-linear features and, therefore, in taking better advantage of the
Searches for other vacua. Part I. Bubbles in our universe
Abstract We discuss models in which vacua other than our own can be directly observed in the present universe. Models with density-dependent vacuum structure can give rise to ‘non-lethal’-vacua:
One Bubble to Rule Them All
We apply the principles of quantum mechanics and quantum cosmology to predict probabilities for our local observations of a universe undergoing false vacuum eternal inflation. At a sufficiently
Lorentzian vacuum transitions: Open or closed universes?
We consider the generalisation of quantum tunneling transitions in the WKB approximation to the time-independent functional Schr\"odinger and Wheeler-DeWitt equations. Following a Lorentzian
Limits on Entanglement Effects in the String Landscape from Planck and BICEP/Keck Data
We consider observational limits on a proposed model of the string landscape in inflation. In this scenario, effects from the decoherence of entangled quantum states in long-wavelength modes in the
M ay 2 01 8 False vacuum decay in kink scattering
In this work we consider kink-antikink and antikink-kink collisions in a modified φ model with a false vacuum characterized by a dimensionless parameter ǫ. The usual φ model is recovered for ǫ = 0.
False vacuum decay in kink scattering

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 provide
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.
Determining the outcome of cosmic bubble collisions in full General Relativity
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
Towards observable signatures of other bubble universes. II. Exact solutions for thin-wall bubble collisions
We assess the effects of a collision between two vacuum bubbles in the thin-wall limit. After describing the outcome of a generic collision possessing the expected hyperbolic symmetry, we focus on
We investigate the effects of gravitation in the collision of two bubbles in the very early universe, using the thin-wall approximation. In general, the collision of two bubbles gives rise to modulus
When do colliding bubbles produce an expanding universe
It is intriguing to consider the possibility that the big bang of the standard (3+1)-dimensional cosmology originated from the collision of two branes within a higher dimensional spacetime, leading
Surviving the crash: Assessing the aftermath of cosmic bubble collisions
This paper is the third in a series investigating the possibility that if we reside in an inflationary “bubble universe,” we might observe the effects of collisions with other such bubbles. Here, we
Eternal inflation, bubble collisions, and the disintegration of the persistence of memory
We compute the probability distribution for bubble collisions in an inflating false vacuum which decays by bubble nucleation. Our analysis generalizes previous work of Guth, Garriga, and Vilenkin to
Cosmic bubble and domain wall instabilities I: parametric amplification of linear fluctuations
This is the first paper in a series where we study collisions of nucleated bubbles taking into account the effects of small initial (quantum) fluctuations in a fully 3+1-dimensional setting. In this
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 collision
