So there was a huge article months ago where some crazy scientists proved theoretically that a spaceship can reach curvature speed (travel Faster than light)
There was a post here days ago that said that speed is relative and you can’t go further than light because it is the only non relative speed (the example was if you stay on a train that goes 9.8c and shoot a bullet that goes 9.8c you can’t exceed C ). So why would their curvature speed work?
Also, side question, wouldn’t they have to worry about asteroids getting in the way when traveling faster than what they can see?
Also, another question, Would travel faster than light make them go back in time? Since If i remember correctly time depends on light or something, wouldn’t go faster than it transform you in The Flash and make you go back in time, Technically letting you arrive before you started traveling?

I am going to cover your question about traveling back in time as I have no idea what the guy was talking about with curvature speed.
As you approach the speed of light time slows down from the perspective of an external observer. If you were on a train going .999999999999 whatever times the speed of light and someone could see you you would be frozen in time forever. From your prospective on the train every second that passed for you stars would form go through their life cycles and die in front of you, maybe even entire stellar nurseries would exhaust between your seconds. You would never travel backward in time from anyone’s perspective.
As far as running into things traveling at high speed oh yes. If it gets stuck in time with you photons etc when you stop whatever is in front of you is going to get ulta gamma busted. If it doesn’t get frozen with you and you hit it (which may be more difficult than you would think because at those speeds you would have a profile like a line because of how stretched you would be) you would probably vaporized into plasma.
