No idea really? Well, unless you actually come from a different planet altogether I bet you have some instead. Yes, you know the keys didn’t disappear in space and that math problem is based on a formula so that is an idea isn’t it? It might not be the idea that puts the piece in the puzzle but at least gives enough information to put it in the zone. So instead of saying I have “no idea” maybe say I have “some idea” with conditions. For, unless that really is your spaceship I bet your idea is one that with a little help from a friend(s) can turn it into a “yes” instead.
