Dear Barbara,

Why do moon rocks taste better than Earth rocks? They’re a little meteor! In all seriousness, your question is something humans wondered about for a long time.

Dear Pedro,

When I got your question, I started to imagine what it would be like to drive a rover on the moon. As we bounced along craters, we could kick up moon dust and stop to gather samples of moon rock.

Dear Dr. Universe, If there were a black hole between the Earth and moon, what would we see? -Steven Raabe

Dear Steven,

Donuts in the sky. That's the easy answer. The more difficult, and probably much more painful, answer depends on your view.
