I was watching a show called "http://www.history.com/shows.do?action=detail&episodeId=373152" [Broken]" on History Channel. It is claimed that someday it may be possible to travel to parallel universes. Does this not violate law of conservation of energy, mass and information? Would this action essentially be subtracting mass, destroying, from this universe and, adding, creating mass, in another? Also, once information left this universe, there would be no way to reconstruct it -- Information is Lost. I know how hard "Mr. Leonard Susskind Ph.D." argued against such phenomena with "Mr. Stephen Hawking Ph.D." on this. Is it a case of overly simplifying the subjecvt to the point that it doesn't make any sense; as per usual on History, Discovery and Discovery Science Channels? Or am I in error and there is no conservation issue related to traveling to parallel universes (and say the traveller died there and did not return?) Would the conversation be shared between the universes? Should Conversation be extended to parallel universes?
