Chatting about what would not work from sci-fi movies (giant ants and force fields), my friend and I became distraught about the Transporter from STAR TREK>
Okay, you walk up on this platform. The machine breaks your body down, changes it to energy and sends this signal somewhere, where it is reconstituted into a replica of your body. Wouldn't you be **dead** as a result of this? There is a copy of you walking around, thinking it's you, having your memories and so forth, but the original person was killed by the first transporter effect. If you believe in any sort of soul or individual spirit, what you see here is a manmade replica of a person stepping down from the transporter. Even if you're a materialist, your real consciousness was exterminated and a copy substituted. I'm going in a shuttle craft, you're not going to get me up on that platform.
