If you simply flew up into space and sawed the moon in half with a giant hacksaw, most likely, nothing would happen. This is because gravitational force would hold the two halves together, sort of like a couple of magnets. But what if you were able to get a couple of giant crowbars and put a person on the other side and then count to 3 and totally separate the two halves of the moon? With enough strength applied, you could theoretically push the two halves far enough apart where the gravitational force no longer pulls them together and now...
