We wouldn’t know the sun was gone for eight-and-a-half minutes. Then Earth would head off in a straight line, into eternal night.
If the sun disappeared, for eight-and-a-half minutes we’d have no idea that the sun had gone. We’d still see it – lingering, like a ghost – in the sky above Earth’s day side. As soon as the last of the sun’s light reached us – eight-and-a-half minutes after the sun itself disappeared – the sun would blink out and night would fall over the entire Earth.
Not until that instant would Earth sail off in a straight line into space. Einstein’s special theory of relativity tells us that no signal in the universe – not even the tug of gravity – can travel faster than the speed of light – about 300,000 kilometers, or 186,000 miles, per second. Though free from the sun’s gravity, we’d be traveling at the same speed as before – about 18 miles, or 30 kilometers per second. So Earth would be traveling at the same speed as always into eternal night.
