(NOTICE: This is a replay of episode 183, one of our favorite Art Bell episodes) Time, the 4th dimension. Is it real? Or is it an illusion created by an interpretation of data in our limited brains? Our best scientists don’t know the answer to this, probably because they’re too busy identifying cat hair for the History Channel. In this, the third of a multi-part series we are exploring those who have already or perhaps have not yet or perhaps always have….travelled through time.
