In order to use statistical independence two variables must be uncorrelated and have zero covariance. The covariance matrix of white noise vector w is an n by n diagonal matrix, and the element Rii represents the variance of component wi. The covariance matrix must also be unidimensional, meaning that its diagonal...

The word black hole can simply be described as a closely packed matter from which nothing, even light, can escape (“10 Amazing Facts About Black Holes”) and (Dunbar, Brian), which flies at an estimated speed of 186,000 miles per second (Richard Talcott).
