The Old Equations, by Jake Kerr

We were wrong about relativity.  Oops.

So goes The Old Equations, by Jake Kerr.  It's good to see there are still room for these stories--take a very simple physics twist and make a story out of it.  So what if we never figured out relativity was real until we tried a FTL flight?

Not too realistic, really.  Once measurements get sensitive, they don't make sense without relativity.  So even if Einstein dies in obscurity, someone else would promulgate the theory in a few years.  But this was still fun.  It illustrates the more basic point that unprecedented exploration carries major risks.  Beyond that, it's done.  Three stars.
