Much changed since Newton suggested the conservation law over 250 years ago; his proposition became popular while it hasn't been checked for all conditions in laboratory, and laboratories were poor for experiments. In recent times has been observed that matter behaves according to different rules in high temperatures (plasma), low temperatures (superconducting) and magnetic field not always obey conservation laws in standard temperatures.
Our moon has many craters and also many strange things. While doing a search of the lunar surface look what I found. NASA doesn't want you to see this. They will probably try and get this airbrushed as soon as possible.
