Gravitational waves may be from primordial fractures in space-time

The early universe may have been such a violent place that space-time itself fractured like a pane of glass. Those fractures would have released floods of gravitational waves, and a team of astronomers has discovered that we may have already detected these ripples in the fabric of space-time.

The team, who reported their results recently in a paper submitted for publication in the Journal of Computational Astrophysics and published on (opens in new tab), claim that they have seen evidence for so-called domain walls in the early universe.
