Just because something isn't scientificaly verifiable doesn't mean it's not worth thinking about. It's definitely amusing to think about. I totally agree with >>10.
The best scientists are people with large minds, generally people who are open to and able to enjoy thinking about various kinds of ideas, definitely including strange ones. Imagine a guy 500 years ago saying 'heeeeeey, maybe we could like, build a giant metal bird shaped thing, and fly in the sky?'
