Can You Have an Answer Without a Question?

Danyo al was thinking, philosophically speaking, can you have an answer without a question? And if we didn't have questions, will we have answers? So i think you got to have questions in order to have answers. This one is from craig, and he has a question about alien technology. If scientists found three functional alien anti gravity guns, what process would they use to understand the physics and technology underlying gun? Basicly, how would they revert a reverse engineerit? Ok as right now you are officially in charge of the project. I give you all the greatest scientists on earth and a 500 billion dollar budget. How would you pull it off?
