FTL travel being impossible is basically the one thing where I completely irrationally reject the science :) It's just too depressing for me to accept. There's gotta be a loophole. There's just gotta be...
The science clearly says FTL is possible: Einstein himself postulated wormholes (known now as Einstein-Rosen bridges), and warp drive has been proven to be possible (though not too practical yet) by Miguel Alcubierre and Sonny White.
