  • A man is sentenced to death on Sunday and told he will be executed on a day in the upcoming week, but it will be a surprise that he will not see coming. He reasons he cannot be executed on the next Sunday, since if he made it to Saturday and was still alive, he would know he was being executed on Sunday since it’s the last day. Because he cannot be executed on Sunday, Saturday becomes the last day and he reasons he can’t be executed then either. He follows this logic all the way down to Monday and concludes that he will not be executed.

    He was executed on Tuesday and was very surprised.





  • Yeah. The idea of a Star Trek-like community of technologically similar alien races all developing in parallel and making alliances/wars with each other is not reflective of reality at all. If we ever encounter aliens, they will either have essentially no technology like animals or will be so far beyond us that they are effectively gods. The odds of us running into a civilization at an even remotely similar level of development are infinitesimal.
