A new study has revealed that seismic waves from the 2011 Tohoku-Oki earthquake in Japan were powerful enough to reflect off the Earth's core and return to the surface, causing a significant slip event that shifted mainland Japan eastward. This phenomenon, previously undetected, highlights a new source of seismic hazard. In a separate development, physicists have proposed a theoretical alternative to black holes called a "gravastar," which would not contain a singularity or event horizon but could instead be dominated by dark energy and potentially trigger the birth of a new universe within itself.
