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? (self.asklemmy)

Yes but as I said, regardless of the method you do to get around the laws of physics, be it bending space or some other novel idea, it still results in the ability to time travel into the past. It creates situations where you can get information before it happens. In a way it places you in two time frames at the same time which is nonsensical. You could send information back to the source before it happened. That is the key point and it breaks causality even if you do it on such a way where you did not actually move. Ie. Wormholes.

This video is really good. About half way thru it shows that it is not so much the movement but that you arrived somewhere before information could have arrived.
