How does Curvature Speed works? Doesn’t it break what we thought was a law of physic?


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?

Could you provide any link to this curvature speed? Because google search does not show anything related to spaceships for me.

Also according to current science there can not be anything faster than light, so its sort of impossible to reply to your last questions.

FTL travel through space is not possible. Full stop, no “but maybe”s, no “that’s just closed minded” no other nonsense like that.

Nobody proved anything. ~~I’ve seen the paper, it’s about as theoretically accurate as the starship Enterprise.~~ it turns out this is a different paper. It still doesn’t prove anything, but there is a possible theoretical framework for the warp drives suggested if you make some unverified assumptions.

There is no telling what would happen if something did go faster than light, because it breaks our universe. It’s like asking “Okay, but if 3>4, what would happen?” I don’t know, it’s impossible to tell.

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.

Picture space as a big rubber sheet, and you have a remote controlled car with a maximum speed driving across it. What if you wanted that car to go “faster”? One way might be to “squish” the sheet under the car, so that even though the car isn’t actually going faster (in terms of how fast its wheels need to spin), it doesn’t need to travel as far. Then when you arrive, you just unsquish the sheet. You could squish the sheet under the whole path you want to take all at once, but you could also just squish the sheet right under the car as it’s driving. As long as the part directly under the car is always squished, then it’s about the same as squishing the whole path. The article you saw suggests a theoretical way of squishing the universe sheet with extremely large masses.

Regarding asteroids, any asteroids that come into the squished space will be travelling at normal speeds relative to your ship, so you can avoid them as easily as if you weren’t squishing space at all. Inside the “bubble”, everything is travelling at normal, sub speed of light speeds. It’s only the apparent speed (The final distance/time measurement) that appears to be faster than C.
