So, random thoughts going through my head, and part of a science fiction novel I'm trying to wrap my head around involves FTL in the future.
Now, according to several papers it appears that the fine structure constant in the universe might not be so, well, constant. A tiny variation to sure, but there. Now, since the whole neutrinos going FTL appears to be all but buried, this is the only viable (however unlikely) appearance of something not going exactly right with C being a constant universal speed limit.
So assuming the results aren't a fluke of statistics/gremlins in the code/etc., AND that the mechanism behind this variability could be manipulated by humans, to produce, in practical effect, an FTL drive my question is this: What would the effects of this look like/work like? And yes, I am assuming that the speed of light is being changed which is what is changing the fine structure constant. It's science fiction after all, the barest hint of plausibility is good enough
