Read too much "Going Postal" by Terry Pratchett ?
In that book, it is discovered that Bloody Johnson invented a machine which bends the universe so that the number "pi" is
exactly 3 ...
The Wizards adviced NOT to stop this macjhine, because stopping would let the universe "explode", so to say, but someone actually did it.
Afterwards, the wizards said that the world "was destroyed in one go and then rebuilt in one go", after the event.
