Overview of the Challenges
Speaker(s): Neil Turok
Abstract:
Date: 12/07/2011 - 9:00 am

Eternal Inflation and it's Implications
Speaker(s): Alan Guth
Abstract: TBA
Date: 12/07/2011 - 9:50 am

Is Eternal Inflation in Our Past?
Speaker(s): Ben Freivogel
Abstract: TBA
Date: 12/07/2011 - 11:20 am

Holographic Cosmology Part 1
Speaker(s): Willy Fischler
Abstract: We will describe how a quantum mechanical description of a flat FRW with equation of state pressure =energy density, emerges.
Date: 12/07/2011 - 12:10 pm

First observational tests of eternal inflation
Speaker(s): Hiranya Peiris
Abstract: The eternal inflation scenario predicts that our observable universe resides inside a single bubble embedded in a vast inflating multiverse. Collisions between bubble universes imprinted in the CMB sky provide a powerful observational test of this idea. I will describe a robust algorithm for non-Gau... read more

On Slow Roll Eternal Inflation
Speaker(s): Leonardo Senatore
Abstract:
Date: 12/07/2011 - 4:30 pm

Cosmic Bubble Collisions
Speaker(s): Matthew Kleban
Abstract: TBA
Date: 12/07/2011 - 5:00 pm

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
Date: 12/07/2011 - 5:30 pm

Eternal Inflation in the Light of Quantum Cosmology
Speaker(s): James Hartle
Abstract: If the universe is a quantum mechanical system it has a quantum state. This state supplies a probabilistic measure for alternative histories of the universe. During eternal inflation these histories typically develop large inhomogeneities that lead to a mosaic structure on superhorizon scales consi... read more
