Yep, that's what I was trying to get at, but failed in my explanation.
Everything's eventually consistent on an ever-present sphere around the incident expanding at the speed of light. No faster.
Even if the sun were to blink out of existence, we'd have 8 minutes that we wouldn't know. Gravity would still be there, holding Earth in place. The light would still warm us. Then 500 seconds later, darkness. We'd be flung out on a tangential course.
