first observational tests of eternal inflation

The eternal inflation scenario predicts that our observable universe resides inside a single bubble
embedded in a vast multiverse, the majority of which is still undergoing super-accelerated expansion.
Many of the theories giving rise to eternal inflation predict that we have causal access to collisions
with other bubble universes, opening up the possibility that observational cosmology can probe the
dynamics of eternal inflation. We present the fi rst observational search for the eff ects of bubble
collisions, using cosmic microwave background data from the WMAP satellite. Using a modular
algorithm that is designed to avoid a posteriori selection eff ects, we find four features on the CMB
sky that are consistent with being bubble collisions. If this evidence is corroborated by upcoming
data from the Planck satellite, we will be able to gain insight into the possible existence of the
multiverse.
