Cryonics with revival is far, far closer in technological achievement (and actually has working science associated with it) than is any realistic FTL travel. Worm holes, Einstein...and those who have further derived his special and general theories of relativity, namely Alcubierre, Natario and White, all towards a "warp" type drive, are at best "speculative". One step above educated fantasy at this point. No working science. Just incomplete math and ideas. FTL.. warp and worm holes are thousands, if not tens of thousands of years beyond us. A suspended animation scenario... about 100 to 150 years....if that far.
