In the movie "Time Machine" where an inventor from the early 1900s (or so) invents a time machine and one of the things he does is go to 2015.
At that point in time, they "screwed up moon demolishioning", and a large chunk (about 1/4) of the moon got broken off, with a crack running across
it literally, and Earth got blasted by meteors, and it led to the destruction of the planet as we know it.
Now, knowing that the moon is hollow, that is there's nothing inside to hold it together, it's a very very good thing they never went ahead with
this!


) but remember, it's just a movie.
