Borzou's right.
Guys, seriously, I'd like a lightsaber, proton pack and delorean time machine as well, but get real.
Look, even if this stuff wasn't “far off,” I highly doubt someone would be able to post in the props how to make a real one. That's because the cost would be enormous, and the materials needed would be things you just don't pick up at your local gas station.
And would you really want one? Would you like to go around and study and chase ghosts? Would you want to devote your life to it?
And how have movies greatly contributed to science over the years. Can you at least give some examples?
Actually it's 180 degrees from that. Science has contributed to movies over the years. All proper sci-fi is only proper if there is an element that is well-researched and somewhat believable. Otherwise it's just a fantasy.
This sort of thing is not real. It is just a movie.
Make the props, that's great, but don't get too caught up in it. Not to this point anyway.
