So, this is a thread for you to post paradoxical, mind-blowing questions about anything. Keeping in mind that you must stay on-topic, limiting your posts to either make your own paradox or to deal with a proposed one.

To give it a start, I'll give you one of mine:

If I told you to walk to a certain point (lets say its 100 meters away), in a straight line, provided that, after each and every step you take, your speed is halved, would you ever reach the point I asked you to reach?





The ''answer'' for this might imply that some things we believed to be coherent are actually not. But that might just be me.
