When Whitley Strieber’s book ‘The Key‘ was published in 2001, on of the Master of the Key’s predictions was that there were other universes beyond our own, an idea generally discredited at the time. But now astrophysicists are theorizing that areas of the universe that are experiencing more rapid rates of expansion than others may have given rise to a multitude of pocket universes, perhaps even exhibiting their own laws of physics. A new study has found potential evidence that these pocket universes may have collided with our own in the distant past.

Using data gathered by the European Space Agency’s Planck telescope, Planck researcher Dr. Ranga-Ram Chary has analyzed a new, more detailed map of the cosmic microwave background (BMB), of which is light left over from the formation of the universe. His search was for bright spots that could indicate energy transfers or releases that might have occurred if another universe had collided with our own.

A previous search for this signature in 2011 using NASA’s WMAP probe yielded no results. However, Chary, using data from Planck’s much more sensitive equipment, found the sought-after bright spots in a map of the signature left by early hydrogen formation — bright spots 4,500 times brighter than his theory predicted.

Other physicists do caution that there are other potential explanations for this phenomenon, such as ordinary foreground dust, that they feel is more probable. Chary’s theory could also see better clarification if NASA’s Primordial Inflation Explorer (PIXIE), an orbital observatory with even more sensitive instruments, is cleared for funding.
