Geometric origin of coincidences and hierarchies in the landscape
Raphael Bousso, Ben Freivogel, Stefan Leichenauer +1
We show that the geometry of cutoffs on eternal inflation strongly constrains predictions for the timescales of vacuum domination, curvature domination, and observation. We conside…
Boundary definition of a multiverse measure
Raphael Bousso, Ben Freivogel, Stefan Leichenauer +1
We propose to regulate the infinities of eternal inflation by relating a late time cut-off in the bulk to a short distance cut-off on the future boundary. The light-cone time of an…
Saturating the holographic entropy bound
Raphael Bousso, Ben Freivogel, Stefan Leichenauer
The covariant entropy bound states that the entropy, S, of matter on a light-sheet cannot exceed a quarter of its initial area, A, in Planck units. The gravitational entropy of bla…
