I am willing to be wrong on this, as I’m not a physicist and I’m going from memory. But I thought that nothing could travel faster than light because spacetime is interconnected. So as something travels “faster” it is simply moving more through spatial dimensions and less through time dimension. Light travels completely through spatial dimensions, leaving no movement through time, which is why nothing can travel “faster” than that. Like if I am walking North-East, I can change direction and travel in a more northerly direction or more easterly direction, but if I’m traveling North, I can’t change directions to travel any more in the northerly direction. I’m already traveling 100% in the northerly direction.
