If I have a strong battery, and I have a cable 2 light years long that stretches 1 LY into space from the battery, bends, and travels 1 LY back to the lightbulb, and the battery and light bulb are 1 meter from each other, how long will it take for the lightbulb to turn on when the circuit is completed/turned on?
