Defect Suspected in Fabric of Space-Time

Eddies in the space-time continuum? Scientists think that shortly after the Big Bang, as the universe cooled and expanded, exotic particles transformed into the particles we know today via phase transitions similar to the gas-liquid-solid transitions that matter now experiences on Earth. And like phase transitions on Earth, defects inevitably occur. When water crystallizes to ice, for example, cloudy spots appear in the ice that mark where water molecules are misaligned. Physicists predict that similar defects happened during the phase transitions of the early universe, and that the defects took different forms. read more | digg story
