We don't know if it will work and even if it does it could kill us. The strain of it could kill us, or the jump could go wrong and kill us or we could jump into a star or a planet or an asteroid and that'd kill us. And even if it all goes perfectly then we're still just stuck on this ship and now we're all exhausted and this thing that's been torturing us for years is even more angry and what are we going to do? Keep pressure on it constantly so it can't jump us right back? Force every jump ourselves with our fingers crossed? This plan is insanely shortsighted.
