The way I think I understand it, even if we had some “element 0” like in mass effect to keep a starship from reaching unmanageable mass while accelerating, faster than light travel still wouldn’t be possible because you’d be violating causality somehow, but every explanation I’ve read on why leaves me bamboozled.
In: 608
Because the speed something is traveling at changes the passage of time for that object. The faster you go, the slower time gets. The speed of light (in a vacuum) is the speed at which the flow of time stops for the object traveling. Any further acceleration would have to make the passage of time slower than time just not passing at all and that is functionally impossible. Even if time was reversed, it would still be passing faster than if it was halted.
I hope that was ELI5 enough
