Metaphysics is a branch of philosophy that explores the fundamental nature of reality, including concepts such as being, existence, and the universe. It seeks to answer questions about what things exist and how they relate to one another, often delving into abstract concepts that go beyond the physical world. This field of study also examines the nature of objects, their properties, and the relationships between them. Metaphysics addresses profound questions like the nature of time and space, causality, and the possibility of free will, making it a crucial area of inquiry in understanding our existence and the universe around us.
