#  Occasionally, I get a letter from someone who is in…

![“Occasionally, I get a letter from someone who is in “contact” with extraterrestrials. I am invited to “ask them anything.” And so over the years I’ve prepared a little list of questions.

So I ask things like, “Please provide a short proof of…” quote by Carl Sagan](https://sms4smile.com/quotes/i/49a/carl-sagan-160_aliens_occasionally-i-get-a-letter-from-someone_2345982.jpg)   [Download](https://sms4smile.com/quotes/i/49a/carl-sagan-160_aliens_occasionally-i-get-a-letter-from-someone_2345982.jpg) [Open image](https://sms4smile.com/quotes/i/49a/carl-sagan-160_aliens_occasionally-i-get-a-letter-from-someone_2345982.jpg)

> ““Occasionally, I get a letter from someone who is in “contact” with extraterrestrials. I am invited to “ask them anything.” And so over the years I’ve prepared a little list of questions. The extraterrestrials are very advanced, remember. So I ask things like, “Please provide a short proof of Fermat’s Last Theorem.” Or the Goldbach Conjecture. And then I have to explain what these are, because extraterrestrials will not call it Fermat’s Last Theorem. So I write out the simple equation with the exponents. I never get an answer. On the other hand, if I ask something like “Should we be good?” I almost always get an answer.””
