Of course, not all scientist's and researchers think these "Inter-Dimensional Travelers" are benevolent and cheerful beings and some theologians go as far as calling them "demonic entities." There is even the possibility that we exist in one or more of these dimensions, but living different lives in each one. My personal belief is that the Universe is filled with quite a few dimensions and that some are home to friendly, peace loving entities and others hold "Inter-Dimensional" beings whose agenda's are evil and corrupt. For lack of better words, I guess you could call them "Angels and Demons."
Traveling into these dimensions is something that has eluded people for thousands of years. (Well, that's what were led to believe, but who knows?) I believe it is possible to travel between dimensions and it can be done through either meditation or bending the fabric of time which creates "wormholes" or doorways to other worlds.
Kind of sounds like what CERN is trying to accomplish huh? I guess we'll find out soon enough when CERN goes full power towards the end of September. I just hope they don't open the doors to Hell releasing demonic beings hell bent on destroying us. We must think positive, we must think positive . . .
