Superpowerful ‘oscillon’ particles could have dominated the infant universe, then vanished

A weird, super-powerful particle that’s not truly a particle could have dominated the universe when it was just a second old, releasing a flood of ripples that permeated all of space-time.

Called oscillons, they would have been so energetic their “ripples” could have unleashed so-called gravitational waves — those vibrations in the fabric of space-time that are generated when monster black holes slam into each other. Future experiments to detect these early-universe gravitational waves could give us insights into the most extreme conditions that the universe has ever encountered.
