In this new paper, http://arxiv.org/abs/gr-qc/0406083 , Lobo & Visser apply linearized gravity to the famous warp drive solutions of Einstein's equations. They are able for the first time to consider an extended (not pointlike) spaceship of finite mass. They find, no surprise, that the warp drives are technologically improbable in the foreseeable future.(adsbygoogle = window.adsbygoogle || []).push({});
