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
If I remember correctly, this is an element of the three body problem series. Essentially some type of warp drive would leave long term effects on the surrounding space-time.
Sort of like nuclear fallout, but at the solar system level. Basically to use it safely, you would need to travel at normal lower than light speed to some empty place and then from there use the FTL warp drive.
