They suggest that as gravitational waves continued to amplify and collide, this led to conditions where small disturbances in space (scalar perturbations) become much larger than gravitational waves.

Oscillons are fascinating structures in theoretical physics, particularly within the realm of scalar field theories. They are localized, time-periodic configurations that can persist for long ...
