In this week's live Questions and Answers show, I provide the exact number of alien worlds that could detect the Earth, are we made of heavier elements made in other galaxies, will lasers remain perfectly parallel in space? And more...

To vote for the best question just post any comment containing its code word. You can use more than one code word if you want.
