The Fission Theory: This theory proposes that the Moon was once part of the Earth and somehow separated from the Earth early in the history of the solar system.
When you actually use that class to make a THING, this is what you make. A method is a bit of code that can be called when needed (often as part of an class, but not always) Here's an example: I write a class called Ball. In my main code, I then write a=Ball.new, b=Ball.new, c=Ball.new.
A lot of OOP fanatics will tell you that the class is an object, and the static method is a method of the class object, rather than it's instances. This phenomenon is less present in Java. Other languages, such as Python allow you to use classes as variables and you can access static methods as methods of that object.
