If you possess the unique combination of characteristics that allow you be both incredibly precise and focused on specific physics problems yet daydreamy enough to stare up at the night sky and wonder “What if?”, you might work for NASA, and you might also be Harold G. White, a NASA physicist who’s researching the possibilities of warp drive travel. (That is, faster than the speed of light.) White has been researching warp travel in a NASA lab, attempting to warp the trajectory of a photon and thus change the distance it travels within a defined area. White’s team is measuring...

Well, I assume they do. They seem to know more about it than anybody. In a breakthrough paper  delivered in the Optics Express journal, IBM has demonstrated their method for greatly improving the  transfer of information between multiple computer chip cores, substituting  optical signals sent through silicon for electrical pulses sent through copper wire.  By greatly shrinking the size of the optical router, or modulator, IBM claims they'll be able to shrink a supercomputer-grade machine down to laptop size. A major challenge for scientists is finding a way to improve communication... Read more...
