I say this in a loose sense. The pretense of the thread is that (like all mad inventors), you must create an object that is designed to solve a problem that will exist in the near-or-far future. I'll provide an example: feel free to comment or critique on it, and by all means make our own! [b]The Navigator's Compass[/b] In light of the discovery of time travel and displacement, chronologists needed to find a infallible way to prevent the creation of time paradoxes in our universe. The prototype and precursor to all forms of anti-paradox devices, the Navigator's Compass is a utility that serves two functions: To direct the user in the best possible direction to create a positive future from information in the present, as well as utilizing quantum mechanics, model constructions of controlled singularities, and zero-point energy to repair the "holes" torn in traveling from era to era. [spoiler]Of course I am far from qualified from talking about this stuff and presenting my details as facts, but such is the work of science fiction. [/spoiler] Enjoy.
