Metaphysics

First, let us know the definition of this Metaphysics. Metaphysics is a branch of philosophy that explores the nature of being, existence, and reality.
Just like mathematics, metaphysics is a non-empirical study which is conducted using analytical thought alone. Like the foundational mathematics (which is sometimes considered a special case of metaphysics applied to the existence of number), it tries to give a coherent account of the structure of the world, capable of explaining our everyday and scientific perception of the world, and being free from contradictions. In mathematics, there are many different ways to define numbers; similarly in metaphysics there are many different ways to define objects, properties, concepts, and other entities which are claimed to make up the world. While metaphysics may, as a special case, study the entities postulated by fundamental science such as atoms and superstrings, its core topic is the set of categories such as object, property and causality which those scientific theories assume. For example: claiming that "electrons have charge" is a scientific theory; while exploring what it means for electrons to be (or at least, to be perceived as) "objects", charge to be a "property", and for both to exist in a topological entity called "space" is the task of metaphysics
