 was undergoing rapid phase change, and theorists believe this state of affairs lasted only some ten trillionth of a ten trillionth of a nanosecond (10-35 seconds) before the particles we see now "condensed" out and froze into space-time. Sparticles have not existed naturally since that time.

However, if this theory is correct, it should be possible to recreate these particles in high-energy particle accelerator
