DISCUSSION
Incidentally, for anyone not au fait with scientific. terminology as used in the video, "sigma" refers to standard deviations in statistics and is a way of measuring the chance of something just being statistical fluctuation. "5-sigma" means there is a 0.0000003 chance that the result is a random fluctuation in the data, and is the level of probability used as a standard to declare something a discovery.
