About: Interdimensional being

An interdimensional being (also extra-dimensional, intra-dimensional) suggests an entity that can "time-travel and move out of the physical body into a spiritual one". The NASA website has a somewhat dated article called "The Science of Star Trek", by physicist David Allen Batchelor (5 May 2009), which considers some of the implementations in Star Trek. He says it's "the only science fiction series crafted with such respect for real science and intelligent writing", with some "imaginary science" mixed in; and considers it to be the "only science fiction series that many scientists watch regularly", like himself. He says it's "more faithful to science than any other science fiction series ever shown on television".
