Aliens have taken you aboard their ship. You will be asked to make a statement. If the statement is true you will be blasted into atoms. If it is false you will be ejected into space. One statement can get you out alive. What is it and how does
it spare you?
You answer, "I will be ejected into space." this saves you because if it were true, you would be blasted into atoms, thus making it untrue. If you were to be ejected into space, that would make it true, so you would have to be blasted into atoms.
