The way you phrase it I agree. I don't know how he asked the original question, it's deleted. But I think it would've been rephrased something like

> If the sun could go super nova (thus, if we changed the size, mass, orbits etc relatively) what would happen from this distance (instead of light years away)

Or

> What happens to the planets with life around a star that goes super nova

Some people say words like "earth" because they don't know the lingo. They hear for the first time stars can go super nova and obviously try to grasp it. But people keep shooting them down. It's not alright. Be flexible.
