I am currently writing a novel that features characters traveling back in time. The main focus of the novel will be the characters and the time period/setting (1934 Chicago) but I did want to have a consistent, well-developed time-travel device. I have been having an enormous amount of trouble coming up with a concept that is satisfactory, though, and I wanted to get people's input on my current idea and maybe suggestions for how to make it better. And, if anybody has any ideas that are completely different than mine, that's fine too... I'd love to hear them. Here is what I envision the device like now: The time-travel device is a spherical object roughly the size of a baseball. I have this concept that it originates from humans living far, far in the future. In my mind, the device looks kind of like a round version of Lemarchand's Cube from the Hellraiser series. Some sort of complex action is performed to "open" the device, so that it can't be activated accidentally. Once it's activated, the device rises several feet in the air and opens to reveal an intensely glowing globe of energy. When you place your hand on the globe, suddenly a digital readout appears in your field of vision, displaying your current date. (Right now it displays Month/Day/Year/Hour/Minute... I have no idea how precise a time-machine would actually allow one to be, but the precision has to end somewhere.) Moving your hand forward or backward on the globe allows you to scroll through the month, then you compress the globe to select it... then it moves on to the day, etc... until you have input the intended destination. Once you have selected a time, you compress it again and you are teleported through time. I just hate this whole concept, though... it's so clunky and unbelievable. Can anybody offer any new ideas or input on my current concept? Thanks!
