What is not matter?

"Not matter" is a term that is often used in philosophical discussions and is related to the concept of negation or non-existence. In some philosophical frameworks, the idea of "not matter" is used to explore the nature of reality and existence beyond the material world.

In a more practical sense, the term "not matter" can also refer to things that are considered insignificant or irrelevant. For example, when someone says "it does not matter", they are often suggesting that something is unimportant or not worth worrying about. This phrase can be used to dismiss or downplay the significance of something in a conversation or situation.
