The speed of light is the speed at which events propagate. Let’s say something happens 8 light-minutes away, for instance the sun explodes. For the first 8 minutes, we’d live in a world where the sun hasn’t exploded yet. Then the event reaches us, and for the first time, we can get information about this event. Perhaps a theoretical physicist can weigh in about whether bent space or a high-dimensional shortcut could change this.
