If we discover the means to travel faster than light, but researching and developing the technology means that the Earth is destroyed in just a few decades, should the technology still be pursued?
Edit: A bunch of yall don't seem to grasp the concept of a theoretical question
I mean surely the research itself isn't actually what destroys the earth, but rather the actual use of such an FTL drive, no? So just research the fundamentals, run a few tests outside the edge of the solar system with unmanned probes, and keep the tech in our pockets in case we actually have a reason to evacuate the planet
