(written from a Production point of view)
In the script for the Star Trek: The Next Generation episode "Q Who", Sonya Gomez waxed philosophically, "And is it here because we believe in it and have therefore created it, or has it created us?" To which, Geordi La Forge said that both the Grand Unified Theory and Supersymmetry had not been seriously discussed for years. In response, Gomez replied that both theories had not been disproved and, although she did know not if the theories were true or not, she had to try and find out. These lines were later cut and did not appear in the episode.
