1st tope, in my sci-fi universe let's say there is a warp drive that can power a ship that can travel 10*c. One of the first things I have people doing is coming up what is called "The Big Picture Project" which is installing this drive onto probes and sending them out unmanned and have it so they will send a constant stream of data back to Earth as they travel away which allows for creating a 3d map of stars around us... #1. How many of these would you send out to do this assuming the probes are constantly moving away from earth in a straight path out? How much redundancy? #2. How between inception of the idea to launch do you think this would take? #3. Would you have a "command center" to handle the incoming data or just let it run automatically? #4. What other benefits do think this would have? #5. How long would you design these to work? The current thing I am saying is that they are designed to last 10,000 years. #6. What are some names you would give these probes? The 4 I am currently using as their names are, Lippershey, Janssen, Metius, and Galileo. ------------------------------------------- 2nd topic, in my universe the alcubierre warp thing has been proven and is usable, but has 2 problems, you can't project the field ahead and there is energy particle build up (both of these are talked about as possible issues in the alcubierre drive article on wiki and I'm saying assume the things that are true to make those things true are true) and so for space use it's pretty much a pre-positioned weapon more so than an actual good way to travel. But I had an idea earlier and I was wonder how feasible it might be... Instead of using it in space couldn't we use it on Earth? You lay the track, step into some vehicle and you are jetted down some track. The speed with which you'd travel would pretty much make it impossible for there to be an accident. But my question is would this be possible and if so, how dangerous would it be? Also this sounds stupid, but would there be a problem turning? If so that would seem to make it automatically only useful for long straight journeysm but would the curvature of the earth cause issues there?
