I hope this belongs here... I believe that I read in some book that there is no such thing as zero probablity events. The example I remember was that if you take the pieces of a broken vase and throw them on the ground, their is a chance that it will put itself back together. The chance is astronomically small, but there none the less. Which gives way to the idea that things peopel perceive as impossible actually aren't. I believe the other one was running through a wall by the electrons of you and the wall lining up perfectly. Am i crazy for stating this? Or did i misread/completely make something up.... Sorry I can't remember the book or article, but I do believe it had something to do with quantum mechanics.
